map of the spread of farming in Turkey/Anatolia/Europe

Hello my Turkish and Turkic readers! In honor of having written a lot on this blog, we’re taking a look back at our most popular posts, and today’s is on the genetic history of Turkey and the Turkic peoples.

Since my original post, I have learned many things about Turkey–mostly that Turks and other Turkic peoples love their culture and heritage. Note: I will probably use “Turkey” and “Anatolia”, interchangeably in this post. Turkey is the name for the modern state located in the region; Anatolia is a more generic name for the geography. I know that “Turkey” as a state or even a people didn’t exist 8,000 years ago.

Turkey has a long and fascinating history. It is possibly the cradle of civilization, as sites like Gobekli Tepe attest, and one of the birthplaces of agriculture.

1280px-j228y-dna29Early farmers spread out from Anatolia into Europe and Asia, contributing much of the modern European gene pool. There are many Y-DNA haplogroups in modern Turkey, which most likely means the Turkish male population hasn’t been completely replaced in recent invasions. (It’s not uncommon for an invasion to wipe out 80+% of the male population in an area.) About 24% of Turkish men carry haplogroup J2, which might not have originated in Turkey all of those centuries ago, but by 12,000 years ago it was common throughout Turkey (and today remains the most common haplogroup). This lineage spread with the Anatolian farmers into Europe around 8,000 years ago. and presumably Asia, as well.

The second most common Y-haplogroup, at 16%, is good old R1b, which was carried into Turkey around 5-6,000 years ago by the Indo-European invaders. (The Indo-European invasion in Spain apparently wiped out all of the local men, but was not nearly so bad in Turkey.) These invaders spoke the Anatolian branch of the Indo-European tree, including Hittite and Luwian.

The Anatolian languages went extinct following Anatolia’s conquest by Alexander the Great in the 4th century BC (though it took several centuries for the languages to fall completely out of use.)

Haplogroup G–11%–is most common in the Caucasus, spread thinly over much of Anatolia and Iran, and even more thinly through Europe, North Africa, and central Asia. It’s probably a pretty old group–Otzi the Iceman was a member of the G clade.

Haplogroup E-M215 is found in about 10% of Turks and is most common in North Africa and the Horn of Africa, but is also quite common in Bedouin populations. It seems likely to be a very old haplogroup.

J1–9%–is common throughout the Middle East and amusingly reaches 46% among Jewish men named “Cohen.”

The rest of Turkish Y-chromosomes hail either from related haplogroups, like R1a, or represent smaller fractions of the population, like Q, 2%, commonly found in Siberia and Native Americans.

(Information on all Turkish Y-haplogroups.)

TurkmenSo how much Turkish DNA hails from Turkic peoples?

Modern Turks don’t speak Anatolian or Greek. They speak a Turkic language, which hails originally from an area near Mongolia. The Turkic-speaking peoples migrated into Anatolia around a thousand years ago, after a long migration/expansion through central Eurasia that culminated with the conquering of Constantinople. Today, the most notable Turkic-speaking groups are the Turks of Turkey,  AzerbaijanisUzbeksKazakhsTurkmen and Kyrgyz people.

The difficulty with tracing Turkic DNA is that, unlike the Mongols, Turkic DNA isn’t terribly homogeneous. The Mongols left a definite genetic signature wherever they went, but imparted less of their language–that is, they killed, raped, and taxed, but didn’t mix much with the locals. By contrast, the Turkic peoples seem to have mixed with their neighbors as they spread, imparting their language and probably not massacring too many people.

According to Wikipedia:

The largest autosomal study on Turkish genetics (on 16 individuals) concluded the weight of East Asian (presumably Central Asian) migration legacy of the Turkish people is estimated at 21.7%.[1]

Note that Turkey shares haplogroup J2 with its Turkic neighbors. This raises an interesting possibility: early Anatolian farmers spread into central Eurasia, mixed with local nomadic Turkic speakers, and then migrated back into Turkey. But 16 people isn’t much of a study.

“South Asian contribution to Turkey’s population was significantly higher than East/Central Asian contributions, suggesting that the genetic variation of medieval Central Asian populations may be more closely related to South Asian populations, or that there was continued low level migration from South Asia into Anatolia.”

“South Asian” here I assume means that Turkey looks more like Iran than Uzbekistan, which is true. The Turkic wanderers likely passed through Iran on their way to Turkey, picking up Iranian culture (such as Islam) and DNA–plus the pre-existing Anatolian population was probably closer to Iran than Uzbekistan anyway.

… the exact kinship between current East Asians and the medieval Oghuz Turks is uncertain. For instance, genetic pools of Central Asian Turkic peoples is particularly diverse and modern Oghuz Turkmens living in Central Asia are with higher West Eurasian genetic component than East Eurasian.[2][3][4]

I think “West Eurasian” is a euphemism for “Caucasian.” East Eurasian (aka Asian) DNA, you can see in the map above, tends to be red+yellow, tending toward all red in Siberia and all yellow in Taiwan. Indo-European groups, including Iranians, tend to have a teal/blue/orange pattern. Turkmen, Uzbeks, and Uygurs, as you can see in the graph, have a combination of both sets of DNA. The Turks also have a small amount of east Asian DNA–but much less–while their neighbors in Iran and central Eurasia share a little Indian DNA.

Several studies have concluded that the genetic haplogroups indigenous to Western Asia have the largest share in the gene pool of the present-day Turkish population.[5][6][7][8][5][9][10][11] An admixture analysis determined that the Anatolian Turks share most of their genetic ancestry with non-Turkic populations in the region and the 12th century is set as an admixture date.[12]

Western Asia=Middle East.

So Turkish DNA is about 22% Turkic, from nomads who entered the country via Iran, and about 78% ancient Anatolian, from the people who had already lived there on the Anatolian plateau for centuries.

But as the Turkic peoples (and many of the comments on my original post) show, culture doesn’t have to be genetic, and many Turkic people feel a strong cultural connection to each other. (And many people report that various Turkic languages are pretty easy to understand if you speak one Turkic language–EG:

hello everyone I’m an Uzbek,

… tatars played a great role in Genghis’s empire and they had an empire after dividing the empire called Golden Horde, it was mongol state but after it became to turki with a time. and their sons are kazakh and kirgiz. Thats why we uzbeks can understand turkish easly more than our neighboors kazakhs. and we uzbeks are not mongoloid like kazakhs.because uzbek language has oghuz and karluk dialect. uzbek-uygur are like turkish-azerbaijani or turkish-crimean tatar. thats why uzbek dialect is most understandable language for every turkic people. but we can understand %95 uygur, %85 turkish-turkmen, %70 azerbaijani %50 kazakh.

Our Uzbeki friend’s full comment is very interesting, and I recommend you read the whole thing.

For that matter, many thanks to everyone who has left interesting comments sharing your family’s histories or personal perspectives on Turkish/Turkic culture and history over the years–I hope you have enjoyed this update.

Neanderthal Skull for 3D Printing

e3fa487b36f43641fc86d1fbe40665b4_preview_featured Meet Nandy the Neanderthal. You can download him at Thingiverse.

This is my first creation, Nandy the Neanderthal, based on the Chapelle-aux-Saints 1 skull and this side view. Note that he is based on two different skulls, but still very much a Neanderthal.

Since this is my very first creation and I don’t have a 3D printer yet, (I expect to receive one soon and am planning ahead,) I am still learning all of the ins and outs of this technology and so would appreciate any technical feedback.

Neanderthals evolved around 600,000-800,000 years ago and spread into the Middle East, Europe, and central Asia. They made stone tools, controlled fire, and hunted. They survived in a cold and difficult climate, but likely could make no more than the simplest of clothes. As a result, they may have been, unlike modern humans, hairy.

Cochran and Harpending of West Hunter write in The 10,000 Year Explosion: 

 Chimpanzees have ridges on their finger bones that stem from the way that they clutch their mothers’ fur as infants. Modern humans don’t have these ridges, but Neanderthals do.

Hoffecker, in The Spread of Modern Humans in Europe writes:

Neanderthal sites show no evidence of tools for making tailored clothing. There are only hide scrapers, which might have been used to make blankets or ponchos. This is in contrast to Upper Paleolithic (modern human) sites, which have an abundance of eyed bone needles and bone awls.

Their skulls were, on average, larger than ours, with wide noses, round eyes, and an elongated braincase. Their facial features were robust–that is, strong, thick, and heavy.

The Chappel-aux-Saints 1 Neanderthal lived to about 40 years old. He had lost most of his teeth years before his death, (I gave Nandy some teeth, though,) suffered arthritis, and must have been cared for in his old age by the rest of his tribe. At his death he was most likely buried in a pit dug by his family, which preserved his skeleton in nearly complete condition for 60,000 years.

Anatomically modern humans, Homo sapiens, encountered and interbred with Neanderthals around 40,000 years ago. (Neanderthals are also humans–Homo neanderthalensis.) Today, about 1-5% of the DNA in non-Sub-Saharan Africans hails originally from a Neanderthal ancestor. (Melanesians also have DNA from a cousin of the Neanderthals, the Denisovans, and Sub-Saharan Africans may have their own archaic ancestors.)

Unfortunately for Nandy and his relations, the Neanderthals also began to disappear around 40,000 years ago. Perhaps it was the weather, or Homo sapiens out competed them, or their enormous skulls just caused too much trouble in childbirth. Whatever happened, the Neanderthals remain a mystery, evidence of the past when we weren’t the only human species in town.

Homeschooling Corner: Summer Fun

Hello, everyone. I hope you have had a lovely summer. We ended up scaling back a bit on our regular schedule, doing about half as much formal “schoolwork” as usual and twice as much riding bikes and going to the playground.

Here are some of the books we found particularly useful/enjoyable this summer:

String, Straightedge, and Shadow: The Story of Geometry, by Julia E Diggins

This is my favorite book we read this summer.

I was looking for a book to introduce simple geometry and shape construction. Instead, I found this delightful history of geometry. It is appropriate for children who understand simple fractions, ratios, and the Pythagorean theorem, but it is not a mathematics textbook and only contains a few equations. (I’m still looking for an introduction to geometry, if anyone has any recommendations.)

This is a new edition of a book originally published in 1965, but its age isn’t really important because geometry hasn’t changed much in the intervening years.

The story begins with geometry in nature–the shapes of trees and flowers, spiderwebs and honeycombs–then develops a speculative account of how early stoneage humans might have become increasingly aware of and attuned to these shapes. Men saw the shapes of the sun and moon in the sky, and might have observed that an ox tied to a pole traced out a similar shape in the dirt.

Then Egyptian surveyors developed right triangles, used for measuring the corner of fields and pyramids. The Mesopotamians developed astronomy, and divided the circle into 360 degrees. Then came the Greeks–clever Thales, mystical Pythagoras, and practical Archimedes. And finally, at the end, Eratosthenes (who used geometry–literally, earth measuring–to measure the circumference of the Earth,) and a few paragraphs about Euclid.

Writing with Ease, by Susan Wise Bauer

There are many books and workbooks in this series, so you can pick the ones that best suit your child’s ability level. (The “look inside the book” feature is great for judging which level of textbook you want.)

I am sure these books are not everyone’s cup of tea. They may not be yours. But they were what we needed.

My eldest children are fairly different in writing needs, but I do not have time for separate curricula. One is a good speller, the other bad. One has acceptable handwriting, the other awful. One will write independently, the other hates writing and plays dead if I try to get them to write. These books have worked well for everyone. Spelling, handwriting, and general willingness to write have all improved.

Even if you aren’t homeschooling, this book might make a good supplement to your kids’ regular curriculum.

In science, we have been growing bacteria in petri dishes and looking at them under the microscope, with the help of Usborne Science and Experiments: The World of the Microscope (I think this is the same book, but cheaper.)

Petri dishes are cheap, agar is easy to make at home (it’s just like making jello,) and kids can learn things like “doorknobs are dirty” and “that’s why mom makes me wash my hands before dinner.”

Just be careful when handling large quantities of bacteria. Even if it’s normal household bacteria that you’re exposed to regularly, you’re not used to it in these quantities. The instructions recommend wearing gloves and safety goggles while handling bacteria and making slides out of them–and besides, kids like dressing up “like scientists” anyway.

The Super Source: Pattern Blocks and Geoboards

Our pattern blocks have been in the family for decades–passed down to me by my grandmother–but the geoboards are a new acquisition. I remember geoboards in elementary school–they sat behind the teacher’s desk and we never actually used them. I didn’t know what, exactly, geoboards were for, so I went ahead and got new workbooks for both them and the pattern blocks.

We are only a few lessons in, but so far I am very pleased with these. We have been talking about angles and measuring the degrees in different shapes with the pattern blocks–360 in a circle, 180 in a triangle, 720 in a hexagon, etc–which dovetails nicely with the geometry reading. The geoboards let us construct and examine a variety of different shapes, like right and equilateral triangles. The lesson plans are easy to use and the kids really enjoy them. Just watch out for rubber bands flying across the room.

Super Source makes workbooks for different grade levels, from K through 6th.

Learn to Program with Minecraft, by Craig Richardson

This book introduces Python, and is a nice step up from the Scratch workbooks. You may have to install a couple of programs, like Python and the API spigot, but the book walks you through this and it is not bad at all. There are then step-by-step instructions for making simple programs, along with bonus challenges to work out on your (or your kid’s) own.

The book covers strings, booleans, if statements, loops, etc, in kid-friendly ways. Best for people who already love Minecraft and can type.

Anthropologyish Friday: Oriental Prisons pt. 4 Egypt

Relevant: Outsourcing Torture and Execution

Welcome back to Anthropology Friday. Today we’re finishing up with Arthur Griffith’s oddly named The History and Romance of Crime: Oriental Prisons. Griffiths was a British prison administrator and inspector of the late 1800s. I am not sure when the book was published, but I believe it was sometime in the early 1900s, for Griffiths mentions events that occurred up to 1899 and died in 1908.

Egypt:

The Code of Hammurabi

“The land of the Pharaohs has ever been governed by the practices and influenced by the traditions of the East. From the time of the Arab conquest, Mohammedan law has generally prevailed, and the old penal code was derived directly from the Koran. Its provisions were most severe, but followed the dictates of common sense and were never outrageously cruel. The law of talion was generally enforced, a life for a life, an eye for an eye, a tooth for a tooth. Murder entailed the punishment of death, but a fine might be paid to the family of the deceased if they would accept it; this was only permitted when the homicide was attended by palliating circumstances. The price of blood varied. It might be the value of a hundred camels; or if the culprit was the possessor of gold, a sum equal to £500 was demanded, but if he possessed silver only, the price asked was a sum equal to £300. …

Compensation in the form of a fine is not now permitted. … The price of blood was incumbent upon the whole tribe or family to which the murderer belonged. A woman convicted of a capital crime was generally drowned in the Nile.

Blood-revenge was a common practice among the Egyptian people. The victim’s relations claimed the right to kill the perpetrator, and relationship was widely extended, for the blood guiltiness included the homicide, his father, grandfather, great-grandfather and great-great-grandfather, and all these were liable to retaliation from any of the relatives of the deceased, who in times past, killed with their own hands rather than appeal to the government, and often did so with disgusting cruelty, even mangling and insulting the corpse. Animosity frequently survived even after retaliation had been accomplished, and blood-revenge sometimes subsisted between neighbouring villages for several years and through many generations.

“Revengeful mutilation was allowed by the law in varying degrees. Cutting off the nose was equivalent to the whole price of blood, or of any two members,—two arms, two hands, or two legs; the removal of one was valued at half the price of blood. The fine of a man for maiming or wounding a woman was just half of that inflicted for injuring a man, if free; if a slave the fine was fixed according to the commercial value of the slave. The whole price of blood was demanded if the victim had been deprived of any of his five senses or when he had been grievously wounded or disfigured for life….

“The modern traveller in Egypt will bear witness to the admirable police system introduced under British rule, and to the security afforded to life and property in town and country by a well organised, well conducted force. In former days, under the Pashas, the whole administration of justice was corrupt from the judge in his court to the police armed with arbitrary powers of oppression….

“Until 1844 the Egyptian police was ineffective, the law was often a dead letter, and the prisons were a disgrace to humanity and civilisation. Before that date the country was covered with zaptiehs, or small district prisons, in which illegal punishment and every form of cruelty were constantly practised. It was quite easy for anyone in authority to consign a fellah to custody. One of the first of the many salutary reforms introduced by the new prison department established under British predominance was an exact registration of every individual received at the prison gate, and the enforcement of the strict rule that no one should be admitted without an order of committal duly signed by some recognised judicial authority.”

Turkey:

“There are few notable buildings in Turkey constructed primarily as prisons. In fact there are few buildings of any sort constructed for that purpose. But every palace had, and one may almost say, still has its prison chambers; and every fortress has its dungeons, the tragedies of which are chiefly a matter of conjecture. Few were present at the tortures, and in a country where babbling is not always safe, witnesses were likely to be discreet.

“In and around Constantinople, if walls had only tongues, strange and gruesome stories might be told. On the Asiatic side of the Bosporus still stand the ruins of a castle built by Bayezid I, known as “the Thunderbolt” when the Ottoman princes were the dread of Europe. Sigismund, King of Hungary, had been defeated, and Constantinople was the next object of attack, though not to fall for a half century. This castle was named “the Beautiful,” but so many prisoners died there of torture and ill-treatment that the name “Black Tower” took its place in common speech.”

EvX: I believe this is Bayezid’s fortress, the Anadolu hisarı, which awkwardly has an i with no dot over it:

Bayezid himself was an interesting character. According to Wikipedia:

Bayezid I … He built one of the largest armies in the known world at the time and unsuccessfully besieged Constantinople. He adopted the title of Sultan-i Rûm, Rûm being an old Islamic name for the Roman Empire.[6] He decisively defeated the Crusaders at Nicopolis (in modern Bulgaria) in 1396, and was himself defeated and captured by Timur at the Battle of Ankara in 1402 and died in captivity in March 1403.

Bayezid I held captive by Timur, painting by Stanisław Chlebowski (1877)

Back to Griffiths:

“Directly opposite, on the European side of the Bosporus, is Rumili Hissar, or the Castle of Europe, which Muhammad II, “the Conqueror,” built in 1452 when he finally reached out to transform the headquarters of Eastern Christendom into the centre of Islam. The castle was built upon the site of the state prison of the Byzantine emperors, which was destroyed to make room for it. The three towers of the castle, and the walls thirty feet thick, still stand.

“In the Tower of Oblivion which now has as an incongruous neighbour, the Protestant institution, Robert College, is a fiendish reminder of days hardly yet gone. A smooth walled stone chute reaches from the interior of the tower down into the Bosporus. Into the mouth of this the hapless victim, bound and gagged perhaps, with weights attached to his feet, was placed. Down he shot and bubbles marked for a few seconds the grave beneath the waters.

“The Conqueror built also the Yedi Kuleh, or the “Seven Towers,” at the edge of the old city. This imperial castle, like the Bastile or the Tower of London, was also a state prison, though its glory and its shame have both departed. The Janissaries who guarded this castle used to bring thither the sultans whom they had dethroned either to allow them to linger impotently or to cause them to lose their heads. A cavern where torture was inflicted and the rusty machines which tore muscles and cracked joints, may still be seen. The dungeons in which the prisoners lay are also shown. A small open court was the place of execution and to this day it is called the “place of heads” while a deep chasm into which the heads were thrown is the “well of blood.”

“Several sultans, (the exact number is uncertain) and innumerable officers of high degree have suffered the extreme penalty here. It was here too that foreign ambassadors were always imprisoned in former days, when Turkey declared war against the states they represented. The last confined here was the French representative in 1798.

The Cage or Kafes, Istanbul

“Another interesting survival of early days is the Seraglio, the old palace of the sultans, and its subsidiary buildings, scattered over a considerable area. In the court of the treasury is the Kafess, or cage, in which the imperial children were confined from the time of Muhammad III, lest they should aspire to the throne. Sometimes however the brothers and sons of the reigning sultan were confined, each in a separate pavilion on the grounds. A retinue of women, pages and eunuchs was assigned to each but the soldiers who guarded them were warned to be strict. The present sultan was confined by his brother Abdul Hamid within the grounds of the Yildiz Kiosk, where he had many liberties but was a prisoner nevertheless. Absolutism breeds distrust of all, no matter how closely connected by ties of blood.”

EvX: The Kafes, strange as it sounds, was real–a prison for princes. According to Wikipedia:

Thereafter, the “rule of elderness” was adopted as the rule of succession in the House of Osmanli so that all males within an older generation were exhausted before the succession of the eldest male in the next generation. …

It became common to confine brothers, cousins and nephews to the Cage, generally not later than when they left the harem (women’s quarters) at puberty. This also marked the end of their education and many sultans came to the throne ill-prepared to be rulers, without any experience of government or affairs outside the Cage. There they had only the company of servants and the women of their harems, occasionally with deposed sultans. …

At different times, it was the policy to ensure that inmates of the Cage only took barren concubines. Consequently, some sultans did not produce sons until they acceded to the throne. These sons, by virtue of their youth at the time of their fathers’ deaths, ensured that the rule of elderness became entrenched …

Confinement in the Cage had a great impact on the personalities of the captives in the Kafes and many of them developed psychological disorders. At least one deposed sultan and one heir committed suicide in the Cage. …

The last Ottoman sultan, Mehmet VI Vahidettin (1918–22) was aged 56 when he came to the throne and had been either in the harem or the Cage his whole life. He was confined to the Cage by his uncle (Abdülaziz) and had stayed there during the reigns of his three older brothers.

This system sounds like it couldn’t possibly have produced good rulers. So after the Turkish sultans condemned their posterity to prison, who actually ran things?

That’s all for today. Everyone take care, follow the law, and stay out of prison!

Book Club: The Code Economy chs. 3-4: Machines and Computers

Machines are fascinating.

Imagine if we discovered, by some chance, in a previously unexplored niche of the world, a group of “people” who looked exactly like us, but had no technology at all: no fire, no pots, no textiles, not even an Acheulean hand axe. Let us further assume that they were not merely feral children who’d gotten lost in the woods, but an actual community that had sustained itself for generations, and that all attempts to introduce them to the art of tool-making failed. They could not, despite often watching others build fires or throw pots, make their own–much less understand and join in a modern economy. (A bulldog can learn to ride a skateboard, but it cannot learn to make a skateboard.)

What would we think of them? Would they be “human”? Even though they look like us, they could only live in houses and wear clothes if we gave those to them; if not given food, they would have to stay in their native environment and hunt.

It is hard to imagine a “human” without technology, nor explaining the course of human history without the advance of technology. The rise of trans-Atlantic discovery, trade, and migration that so fundamentally shaped the past 500 years cannot be explained without noting the development of superior European ships, maps, and navigational techniques necessary to make the journey. Why did Europe discover America and not the other way around? Many reasons, but fundamentally, because the Americans of 1492 didn’t have ships that could make the journey and the Europeans did.

The Romans were a surprisingly advanced society, technology wise, and even during the High Middle Ages, European technology continued to advance, as with the spread of wind and water mills. But I think it was the adoption of (Hindu-)Arabic numerals, popularized among mathematicians in the 1200s by Fibonacci, but only adopted more widely around the 1400s, that really allowed the Industrial and Information Revolutions to occur. (Roman numerals are just awful for any maths.)

An 18th century set of Napier’s Bones

From the Abacus and Fibonacci’s Liber Abaci, Napier developed his “bones,” the first European mechanical calculating machine, in 1617. These were followed by Pascal’s Calculator in 1642, the slide rule (early 1600s,) and Leibniz’s Stepped Reckoner in 1672. After that, progress on the adding machine problem was so rapid that it does not do to list all of the devices and prototypes devised, but we may mention Gaspard de Prony’s impressive logarithmic and trigonometric mathematical tables, for use by human “calculators”, and Babbage‘s analytical and difference machines. The Arithmometer, patented in 1820, was the first commercially successful mechanical calculator, used in many an office for nearly a century.

The history of mechanical computing devices wouldn’t be complete without reference to the parallel development of European clocks and watches, which pioneered the use of gears to translate movement into numbers, not to mention the development of an industry capable of manufacturing small, high-quality gears to reasonably high tolerances.

Given this context, I find our culture’s focus on Babbage–whose machines, while impressive, was never actually built–and his assistant Ada of Lovelace, a bit limited. Their contributions were interesting, but taken as a whole, the history is almost an avalanche of innovations.

Along the way, the computer has absorbed many technological innovations from outside computing–the Jacquard Loom pioneered the use of punch cards; the lightbulb pioneered the vacuum tubes that eventually filled Colossus and ENIAC.

But these early computers had a problem: vacuum tubes broke often.

During and immediately after World War II a phenomenon named “the tyranny of numbers” was noticed, that is, some computational devices reached a level of complexity at which the losses from failures and downtime exceeded the expected benefits.[2] Each Boeing B-29 (put into service in 1944) carried 300–1000 vacuum tubes and tens of thousands of passive components.[notes 4] The number of vacuum tubes reached thousands in advanced computers and more than 17,000 in the ENIAC (1946).[notes 5] Each additional component reduced the reliability of a device and lengthened the troubleshooting time.[2] Traditional electronics reached a deadlock and a further development of electronic devices required reducing the number of their components.

Also:

…the 1946 ENIAC, with over 17,000 tubes, had a tube failure (which took 15 minutes to locate) on average every two days. The quality of the tubes was a factor, and the diversion of skilled people during the Second World War lowered the general quality of tubes.[29]

The invention of the semiconductor further revolutionized computing–bringing us a long way from the abacus of yesterday.

Chapter 3 takes a break from the development of beautiful machines to examine their effects on humans. Auerswald writes:

By the twentieth century, the systematic approach to analyzing the division of labor that de Prony developed would have a name: management science. the first and foremost proponent of management science was Frederick Winslow Taylor, a child of privilege who found his calling in factories. …

This first experience of factory work gave Taylor an understanding of the habits of workers that was as intimate as it was, ultimately, unfavorable. Being highly organized and precise by nature, Taylor was appalled at the lax habits and absence of structure that characterized the early twentieth-century factory floor. … However, Taylor ultimately concluded that the blame did not lie with the workers but in the lack of rigorously considered management techniques. At the center of management, Taylor determined, was the capacity to precisely define the tasks of which a “job” was comprised.

What distinguished Taylor was his absolute conviction that worker could not be left on their own to define, much less refine, the tasks that comprised their work. He argued that authority must be fully vested in scientifically determined routine–that is to say, code.

Sounds hellish.

I know very little of management science beyond what can be found in Charlie Chaplin’s Modern Times. According to Wikipedia, Vladimir Lenin described Taylorism as a “‘scientific’ system of sweating” more work from laborers.[3] However, in Taylor’s defense, I don’t think the adoption of Taylorism ever resulted in the mass starvation of millions of people, so maybe Lenin should shut up was wrong. Further:

In the course of his empirical studies, Taylor examined various kinds of manual labor. For example, most bulk materials handling was manual at the time; material handling equipment as we know it today was mostly not developed yet. He looked at shoveling in the unloading of railroad cars full of ore; lifting and carrying in the moving of iron pigs at steel mills; the manual inspection of bearing balls; and others. He discovered many concepts that were not widely accepted at the time. For example, by observing workers, he decided that labor should include rest breaks so that the worker has time to recover from fatigue, either physical (as in shoveling or lifting) or mental (as in the ball inspection case). Workers were allowed to take more rests during work, and productivity increased as a result.[11]

Also:

By factoring processes into discrete, unambiguous units, scientific management laid the groundwork for automation and offshoring, prefiguring industrial process control and numerical control in the absence of any machines that could carry it out. Taylor and his followers did not foresee this at the time; in their world, it was humans that would execute the optimized processes. (For example, although in their era the instruction “open valve A whenever pressure gauge B reads over value X” would be carried out by a human, the fact that it had been reduced to an algorithmic component paved the way for a machine to be the agent.) However, one of the common threads between their world and ours is that the agents of execution need not be “smart” to execute their tasks. In the case of computers, they are not able (yet) to be “smart” (in that sense of the word); in the case of human workers under scientific management, they were often able but were not allowed. Once the time-and-motion men had completed their studies of a particular task, the workers had very little opportunity for further thinking, experimenting, or suggestion-making. They were forced to “play dumb” most of the time, which occasionally led to revolts.

While farming has its rhythms–the cows must be milked when the cows need to be milked, and not before or after; the crops must be harvested when they are ripe–much of the farmer’s day is left to his own discretion. Whether he wants to drive fence in the morning and hoe the peas in the afternoon, or attend to the peas first and the fence later is his own business. If he wants to take a nap or pause to fish during the heat of the day it is, again, his own business.

A factory can’t work like that. If the guy who is supposed to bolt the doors onto the cars can’t just wander off to eat a sandwich and use the restroom whenever he feels like it, nor can he decide that today he feels like installing windshields. Factories and offices allow many men to work together by limiting the scope of each one’s activities.

Is this algorithmisation of labor inhuman, and should we therefore welcome its mechanization and automation?

Anthropology Friday: Appalachia, pt 2/4

Gutierrez map of 1562 showing Appalachia

Welcome back to Anthropology Friday. Today were are continuing with Kephart’s Our Southern Highlanders, published in 1913.

Physical appearance:

“Spartan diet does not put on flesh. Still, it should be noted that long legs, baggy clothing, and scantiness or lack of underwear make people seem thinner than they really are. Our highlanders are conspicuously a tall race. Out of seventy-six men that I have listed just as they occurred to me, but four are below average American height and only two are fat. About two-thirds of them are brawny or sinewy fellows of great endurance. The others generally are slab-sided, stoop-shouldered, but withey. The townsfolk and the valley farmers, being better nourished and more observant of the prime laws of wholesome living, are noticeably superior in appearance but not in stamina.”

EvX: I cannot help but think we have lost something of healthy stamina.

“There is a wealthy man known to everyone around Waynesville, who, being asked where he resided, as a witness in court, answered: “Three, four miles up and down Jonathan Creek.” The judge was about to fine him for contempt, when it developed that the witness spoke literal truth. He lives neither in house nor camp, but perambulates his large estate and when night comes lies down wherever he may happen to be. In winter he has been known to go where some of his pigs bedded in the woods, usurp the middle for himself, and borrow comfort from their bodily heat.”

EvX: I do not now about you, but I feel a kind of kinship with this man. Often I feel a restlessness, a sense that I am trapped by the walls of my house. It is not a dissatisfaction with the people in my house–toward them I feel no restlessness at all–but the house itself.

I am at peace again when I find myself in the woods, the trees towering over me; I am at peace in the snow, drifting through a blizzard. I am at peace in a fog, the world shut out by a faded haze. In the distance I see the mountains, and though I am walking to the playground or the shops they tug at me, and I am always tempted to turn my feet and just keep going until I arrive.

I do not want a large or fancy house; I just want to live in the woods among the plants and people I love.

But back to the man in the woods in the court:

“This man is worth over a hundred thousand dollars. He visited the world’s fairs at Chicago and St. Louis, wearing the old long coat that serves him also as blanket, and carrying his rations in a sack. Far from being demented, he is notoriously so shrewd on the stand and so learned in the law that he is formidable to every attorney who cross-questions him.”

Religion:

“The first settlers of Appalachia mainly were Presbyterians, as became Scotch-Irishmen, but they fell away from that faith, partly because the wilderness was too poor to support a regular ministry, and partly because it was too democratic for Calvinism with its supreme authority of the clergy. This much of seventeenth century Calvinism the mountaineer retains: a passion for hair-splitting argument over points of doctrine, and the cocksure intolerance of John Knox; but the ancestral creed itself has been forgotten.

“The circuit-rider, whether Methodist or Baptist, found here a field ripe for his harvest. Being himself self-supporting and unassuming, he won easily the confidence of the people. He preached a highly emotional religion that worked his audience into the ecstasy that all primitive people love. And he introduced a mighty agent of evangelization among outdoor folk when he started the camp-meeting.

“The season for camp-meetings is from mid-August to October. The festival may last a week in one place. It is a jubilee-week to the work-worn and home-chained women, their only diversion from a year of unspeakably monotonous toil. And for the young folks, it is their theater, their circus, their county fair. (I say this with no disrespect: “big-meetin’ time” is a gala week, if there be any such thing at all in the mountains—its attractiveness is full as much secular as spiritual to the great body of the people.)”

EvX: Vacation Bible Camp is still a thing, of course.

“It is a camp by day only, or up to closing time. No mountaineer owns a tent. Preachers  and exhorters are housed nearby, and visitors from all the country scatter about with their friends, or sleep in the open, cooking their meals by the wayside.

“In these backwoods revival meetings we can witness to-day the weird phenomena of ungovernable shouting, ecstasy, bodily contortions, trance, catalepsy, and other results of hypnotic suggestion and the contagious one-mindedness of an overwrought crowd. This is called “taking a big through,” and is regarded as the madness of supernatural joy. It is a mild form of that extraordinary frenzy which swept the Kentucky settlements in 1800, when thousands of men and women at the camp-meetings fell victims to “the jerks,” “barking exercises,” erotic vagaries, physical wreckage, or insanity, to which the frenzy led.

Christian snake handlers

“Many mountaineers are easily carried away by new doctrines extravagantly presented. Religious mania is taken for inspiration by the superstitious who are looking for “signs and wonders.” At one time Mormon prophets lured women from the backwoods of western Carolina and eastern Tennessee. Later there was a similar exodus of people to the Castellites, a sect of whom it was commonly remarked that “everybody who joins the Castellites goes crazy.” In our day the same may be said of the Holy Rollers and Holiness People.”

EvX: Wikipedia appears to have nothing on the Castellites, but Wiktionary says they were a religious group in North Carolina in the late 19th century.

Language:

“An editor who had made one or two short trips into the mountains once wrote me that he thought the average mountaineer’s vocabulary did not exceed three hundred words. This may be a natural inference if one spends but a few weeks among these people and sees them only under the prosaic conditions of workaday life. But gain their intimacy and you shall find that even the illiterates among them have a range of expression that is truly remarkable. I have myself taken down from the lips of Carolina mountaineers some eight hundred dialectical or obsolete words, to say nothing of the much greater number of standard English terms that they command. …

“Our highlander often speaks in Elizabethan or Chaucerian or even pre-Chaucerian terms. His pronoun hit antedates English itself, being the Anglo-Saxon neuter of he. Ey God, a favorite expletive, is the original of egad, and goes back of Chaucer. Ax for ask and kag for keg were the primitive and legitimate forms, which we trace as far as the time of Layamon. When the mountain boy challenges his mate: “I dar ye—I ain’t afeared!” his verb and participle are of the same ancient and sterling rank. Afore, atwixt, awar, heap o’ folks, peart, up and done it, usen for used, all these everyday expressions of the backwoods were contemporary with the Canterbury Tales.

“A man said to me of three of our acquaintances: “There’s been a fray on the river—I don’t know how the fraction begun, but Os feathered into Dan and Phil, feedin’ them lead.” He meant fray in its original sense of deadly combat, as was fitting where two men were killed. Fraction for rupture is an archaic word, rare in literature, though we find it in Troilus and Cressida. “Feathered into them!” Where else can we hear to-day a phrase that passed out of standard English when “villainous saltpetre” supplanted the long-bow? It means to bury an arrow up to the feather, as when the old chronicler Harrison says, “An other arrow should haue beene fethered in his bowels.”

Social Organization (or lack thereof):

“Bear in mind that in the mountains every person is accorded the consideration that his own qualities entitle him to, and no whit more. It has always been so. Our Highlanders have neither memory nor tradition of ever having been herded together, lorded over, persecuted or denied the privileges of free-men. So, even within their clans, there is no servility nor any headship by right of birth. Leaders arise, when needed, only by virtue of acknowledged ability and efficiency. In this respect there is no analogy whatever to the clan system of ancient Scotland, to which the loose social structure of our own highlanders has been compared.

“We might expect such fiery individualism to cool gradually as population grew denser; but, oddly enough, crowding only intensifies it in the shy backwoodsman. Neighborliness has not grown in the mountains—it is on the wane. There are to-day fewer log-rollings and house-raisings, fewer husking bees and quilting parties than in former times; and no new social gatherings have taken their place. Our mountain farmer, seeing all arable land taken up, and the free range ever narrowing, has grown jealous and distrustful, resenting the encroachment of too many sharers in what once he felt was his own unfenced domain. And so it has come about that the very quality that is his strength and charm as a man—his staunch individualism—is proving his weakness and reproach as a neighbor and citizen. The virtue of a time out-worn has become the vice of an age new-born.

The mountaineers are non-social. As they stand to-day, each man “fighting for his own hand, with his back against the wall,” they recognize no social compact. Each one is suspicious of the other. Except as kinsmen or partisans they cannot pull together. Speak to them of community of interests, try to show them the advantages of co-operation, and you might as well be proffering advice to the North Star. They will not work together zealously even to improve their neighborhood roads, each mistrusting that the other may gain some trifling advantage over himself or turn fewer shovelfuls of earth. Labor chiefs fail to organize unions or granges among them because they simply will not stick together.”

 

Book Club: The Code Economy ch. 1

Greetings! Grab a cup of coffee and pull up a chair. Tea is also good. Today we’re diving into chapter one of Philip Auerswald’s The Code Economy, “Jobs: Divide and Coordinate.”

I wish this chapter had been much longer; we speed through almost 2.5 million years of cognitive evolution in a couple of pages.

The earliest hominins had about the same short-term memory as a modern-day chimpanzee, which is to say they could keep track of only two operations at a time. … Our methods for creating tools gradually became more sophisticated, until we were using the tools we created to produce other tools in a repetitive and predictable manner. These processes for creating stone tools were among humanity’s first production algorithms-that is, the earliest code. They appeared almost simultaneously in human communities in most part of the world around 40,000 BC.

Footnote:

…[E.O.] Wilson refers to this phenomenon more broadly as the discovery of eusocial behavior… Wilson situates the date far earlier in human history than I do here. I chose 50,000 years [ago] because my focus is on the economy. it is clear that an epochal change in society occurred roughly 10,000 years BCE, when humans invented agriculture in six parts of the world simultaneously. The fact of this simultaneity directly suggests the advance of code represented by the invention of agriculture was part of a forward movement of code that started much earlier.

What do you think? Does the simultaneous advent of behavioral modernity–or eusociality–in far-flung human groups roughly 50,000 years ago, followed by the simultaneous advent of agriculture in several far-flung groups about 10,000 years ago speak to the existence of some universal, underlying process? Why did so many different groups of people develop similar patterns of life and technology around the same time, despite some of them being highly isolated? Was society simply inevitable?

The caption on the photo is similarly interesting:

Demand on Short-Term Working Memory in the Production of an Obsidian Axe [from Read and van der Leeuw, 2015] … We can relate the concepts invoked in the prodcution of stone tools to the number of dimensions involved and thereby to the size of short-term workign memory (STWM) required for the prodction of the kind of stone tools that exemplify each stage in hominin evolution. …

Just hitting the end of a pebble once to create one edge, as in the simplest tools, they calculate requires holding three items in the working memory. Removing several flakes to create a longer edge (a line), takes STWM 4; working an entire side takes STWM 5; and working both sides of the stone in preparation for knapping flakes from the third requires both an ability to think about the pebble’s shape in three dimensions and STWM 7.

(The Wikipedia article on Lithic Reduction has a lovely animation of the technique.)

It took about 2 million years to proceed from the simplest tools (working memory: 3) to the most complex (working memory: 7.) Since the Neolithic, our working memory hasn’t improved–most of us are still limited to a mere 7 items in our working memory, just enough to remember a phone number if you already know the area code.

All of our advances since the Neolithic, Auerswald argues, haven’t been due to an increase in STWM, but our ability to build complexity externally: through code. And it was this invention of code that really made society take off.

By about 10,000 BCE, humans had formed the first villages… Villages were the precursors of modern-day business firms in that they were durable association built around routines. … the advance of code at the village level through the creation of new technological combinations set into motion the evolution from simplicity to complexity that has resulted in the modern economy.

It was in the village, then, that code began to evolve.

What do you think? Are Read and van der Leeuw just retroactively fitting numbers 3-7 to the tools, or do they really show an advance in working memory? Is the village really the source of most code evolution? And who do you think is more correct, Herbert Spencer or Thomas Malthus?

Auerswald then forward to 1557, with the first use of the word “job” (spelled “jobbe,” most likely from “gobbe,” or lump.)

The advent of the “jobbe” a a lump of work was to the evolution of modern society something like what the first single-celled organism was to the evolution of life.

!

The “jobbe” contrasted with the obligation to perform labor continuously and without clearly defined roles–slavery, serfdom, indentured servitude, or even apprenticeship–as had been the norm throughout human history.

Did the Black Death help create the modern “job market” by inspiring Parliament to pass the Statute of Laborers?

I am reminded here of a passage from Gulick’s Evolution of the Japanese, Social and Psychic, (published in 1903):

The idea of making a bargain when two persons entered upon some particular piece of work, the one as employer, the other as employed, was entirely repugnant to the older generation, since it was assumed that their relations as inferior and superior should determine their financial relations; the superior would do what was right, and the inferior should accept what the superior might give without a question or a murmur. Among the samurai, where the arrangement is between equals, bargaining or making fixed and fast terms which will hold to the end, and which may be carried to the courts in case of differences, was a thing practically unknown in the older civilization. Everything of a business nature was left to honor, and was carried on in mutual confidence.

“A few illustrations of this spirit of confidence from my own experience may not be without interest. On first coming to Japan, I found it usual for a Japanese who wished to take a jinrikisha to call the runner and take the ride without making any bargain, giving him at the end what seemed right. And the men generally accepted the payment without question. I have found that recently, unless there is some definite understanding arrived at before the ride, there is apt to be some disagreement, the runner presuming on the hold he has, by virtue of work done, to get more than is customary. This is especially true in case the rider is a foreigner. Another set of examples in which astonishing simplicity and confidence were manifested was in the employment of evangelists. I have known several instances in which a full correspondence with an evangelist with regard to his employment was carried on, and the settlement finally concluded, and the man set to work without a word said about money matters. It need hardly be said that no foreigner took part in that correspondence. …

“This confidence and trustfulness were the product of a civilization resting on communalistic feudalism; the people were kept as children in dependence on their feudal lord; they had to accept what he said and did; they were accustomed to that order of things from the beginning and had no other thought; on the whole too, without doubt, they received regular and kindly treatment. Furthermore, there was no redress for the peasant in case of harshness; it was always the wise policy, therefore, for him to accept whatever was given without even the appearance of dissatisfaction. This spirit was connected with the dominance of the military class. Simple trustfulness was, therefore, chiefly that of the non-military classes.

“Since the overthrow of communal feudalism and the establishment of an individualistic social order, necessitating personal ownership of property, and the universal use of money, trustful confidence is rapidly passing away.

We still identify ourselves with our profession–“I am a doctor” or “I am a paleontologist”–but much less so than in the days when “Smith” wasn’t a name.

Auerswald progresses to the modern day:

In the past two hundred years, the complexity of human economic organization has  increased by orders of magnitude. Death rates began to fall rapidly in the middle of the nineteenth century, due to a combination of increased agricultural output, improved hygiene, and the beginning of better medical practices–all different dimensions of the advance of code…. Greater numbers of people living in greater density than ever before accelerated the advance of code.

Sounds great, but:

By the twentieth century, the continued advance of code necessitated the creation of government bureaucracies and large corporations that employed vast numbers of people. These organizations executed code of sufficient complexity that it was beyond the capacity of any single individual to master.

I’ve often wondered if the explosion of communist disasters at the beginning of the 20th century occurred because we could imagine a kind of nation-wide code for production and consumption and we had the power to implement it, but we didn’t actually have the capabilities and tools necessary to make it work.

We can imagine Utopia, but we cannot reach it.

Auerswald delineates two broad categories of “epochal change” as a result of the code-explosion of the past two centuries: First, our capabilities grew. Second:

“we have, to an increasing degree, ceded to other people–and to code itself–authority and autonomy, which for millennia we had kept unto ourselves and our immediate tribal groups as uncodified cultural norms.”

Before the “job”, before even the “trade,” people lived and worked far more at their own discretion. Hoeing fields or gathering yams might be long and tedious work, but at least you didn’t have to pee in a bottle because Amazon didn’t give you time for bathroom breaks.

Every time voters demand that politicians “bring back the jobs” or politicians promise to create them, we are implicitly stating that the vast majority of people are no longer capable of making their own jobs. (At least, not jobs that afford a modern lifestyle.) The Appalachians lived in utter poverty (the vast majority of people before 1900 lived in what we would now call utter poverty), but they did not depend on anyone else to create “jobs” for them; they cleared their own land, planted their own corn, hunted their own hogs, and provided for their own needs.

Today’s humans are (probably not less intelligent nor innately capable than the average Appalachian of 1900, but the economy (and our standards of living) are much more complex. The average person no longer has the capacity to drive job growth in such a complicated system, but the solution isn’t necessarily for everyone to become smarter. After all, large, complicated organizations need hundreds of employees who are not out founding their own companies.

But this, in turn, means all of those employees–and even the companies themselves–are dependent on forces far outside their control, like Chinese monetary policy or the American electoral cycle. And this, in turn, raises demand for some kind of centralized, planned system to protect the workers from economic hardship and ensure that everyone enjoys a minimum standard of living.

Microstates suggest themselves as a way to speed the evolution of economic code by increasing the total number of organisms in the ecosystem.

With eusociality, man already became a political (that is, polis) animal around 10,000 or 40,000 or perhaps 100,000 years ago, largely unable to subsist on his own, absent the tribe. We do not seem to regret this ill-remembered transition very much, but what about the current one? Is the job-man somehow less human, less complete than the tradesman? Do we feel that something essential to the human spirit has been lost in defining and routinizing our daily tasks down to the minute, forcing men to bend to the timetables of factories and international corporations? Or have we, through the benefits of civilization (mostly health improvements) gained something far richer?

What IS “Social Studies”?

Sometimes you can’t see the forest for the trees, and sometimes you look at your own discipline and can’t articulate what, exactly, the point of it is.

Yes, I know which topics social studies covers. History, civics, geography, world cultures, reading maps, traffic/pedestrian laws, etc. Socialstudies.org explains, “Within the school program, social studies provides coordinated, systematic study drawing upon such disciplines as anthropology, archaeology, economics, geography, history, law, philosophy, political science, psychology, religion, and sociology, as well as appropriate content from the humanities, mathematics…” etc. (I’m sure you did a lot of archaeology back in elementary school.)

But what is the point of lumping all of these things together? Why put psychology, geography, and law into the same book, and how on earth is that coordinated or systematic?

The points of some other school subjects are obvious. Reading and writing allow you to decode and encode information, a process that has massively expanded the human ability to learn and “remember” things by freeing us from the physical constraints of our personal memories. We can learn from men who lived a thousand years ago or a thousand miles away, and add our bit to the Great Conversation that stretches back to Homer and Moses.

Maths allow us to quantify and measure the world, from “How much do I owe the IRS this year?” to “Will this rocket land on the moon?” (It is also, like fiction, pleasurable for its own sake.) And science and engineering, of course, allow us to make and apply factual observations about the real world–everything from “Rocks accelerate toward the earth at a rate of 9.8m/s^2” to “This bridge is going to collapse.”

But what is social studies? The question bugged me for months, until Napoleon Chagnon–or more accurately, the Yanomamo–provided an answer.

Chagnon is a anthropologist who carefully documented Yanomamo homicide and birth rates, and found that the Yanomamo men who had killed the most people went on to father the most children–providing evidence for natural selection pressures making the Yanomamo more violent and homicidal over time, and busting the “primitive peoples are all lovely egalitarians with no crime or murder” myth.

In an interview I read recently, Chagnon was asked what the Yanomamo made of him, this random white guy who came to live in their village. Why was he there? Chagnon replied that they thought he had come:

“To learn how to be human.”

Sometimes we anthropologists lose the signal in the noise. We think our purpose is to document primitive tribes before they go extinct (and that is part of our purpose.) But the Yanomamo are correct: the real reason we come is to learn how to be human.

All of school has one purpose: to prepare the child for adulthood.

The point of social studies is prepare the child for full, adult membership in their society. You must learn the norms, morals, and laws of your society. The history and geography of your society. You learn not just “How a bill becomes a law” but why a bill becomes a law. If you are religious, your child will also learn about the history and moral teachings of their religion.

Most religions have some kind of ceremony that marks the beginning of religious adulthood. For example, many churches practice the rite of Confirmation, in which teens reaffirm their commitment to Christ and become full members of the congregation. Adult Baptism functions similarly in some denominations.

Judaism has the Bar (and Bat) Mitzvah, whose implications are quite clearly articulated. When a child turns 13 (or in some cases, 12,) they are now expected to be moral actors, responsible for their own behavior. They now make their own decisions about following Jewish law, religious duties, and morality.

But there’s an upside: the teen is also now able to part of a minyan, the 10-person group required for (certain) Jewish prayers, Torah legal study; can marry*; and can testify before a Rabbinic court.

*Local laws still apply.

In short, the ceremony marks the child’s entry into the world of adults and full membership in their society. (Note: obviously 13 yr olds are not treated identically to 33 yr olds; there are other ceremonies that mark the path to maturity.)

Whatever your personal beliefs, the point of Social Studies is to prepare your child for full membership in society.

A society is not merely an aggregation of people who happen to live near each other and observe the same traffic laws (though that is important.) It is a coherent group that believes in itself, has a common culture, language, history, and even literature (often going back thousands of years) about its heroes, philosophy, and values.

To be part of society is to be part of that Great Conversation I referenced above.

But what exactly society is–and who is included in it–is a hotly debated question. Is America the Land of the Free and Home of the Brave, or is it a deeply racist society built on slavery and genocide? As America’s citizens become more diverse, how do these newcomers fit into society? Should we expand the canon of Great Books to reflect our more diverse population? (If you’re not American, just substitute your own country.)

These debates can make finding good Social Studies resources tricky. Young students should not be lied to about their ancestors, but neither should they be subjected to a depressing litany of their ancestors’ sins. You cannot become a functional, contributing member of a society you’ve been taught to hate or be ashamed of.

Too often, I think, students are treated to a lop-sided curriculum in which their ancestors’ good deeds are held up as “universal” accomplishments while their sins are blamed on the group as a whole. The result is a notion that they “have no culture” or that their people have done nothing good for humanity and should be stricken from the Earth.

This is not how healthy societies socialize their children.

If you are using a pre-packaged curriculum, it should be reasonably easy to check whether the makers hold similar values as yourself. If you use a more free-form method (like I do,) it gets harder. For example, YouTube* is a great source for educational videos about all sorts of topics–math, grammar, exoplanets, etc.–so I tried looking up videos on American history. Some were good–and some were bad.

*Use sensible supervision

For example, here’s a video that looked good on the thumbnail, but turned out quite bad:

From the description:

In which John Green teaches you about the Wild, Wild, West, which as it turns out, wasn’t as wild as it seemed in the movies. When we think of the western expansion of the United States in the 19th century, we’re conditioned to imagine the loner. The self-reliant, unattached cowpoke roaming the prairie in search of wandering calves, or the half-addled prospector who has broken from reality thanks to the solitude of his single-minded quest for gold dust. While there may be a grain of truth to these classic Hollywood stereotypes, it isn’t a very big grain of truth. Many of the pioneers who settled the west were family groups. Many were immigrants. Many were major corporations. The big losers in the westward migration were Native Americans, who were killed or moved onto reservations. Not cool, American pioneers.

Let’s work through this line by line. What is the author’s first priority: teaching you something new about the West, or telling you that the things you believe are wrong?

Do you think it would be a good idea to start a math lesson by proclaiming, “Hey kids, I bet you get a lot of math problems wrong”? No. Don’t start a social studies lesson that way, either.

There is no good reason to spend valuable time bringing up incorrect ideas simply because a child might hold them; you should always try to impart correct information and dispel incorrect ideas if the child actually holds them. Otherwise the child is left not with a foundation of solid knowledge, but with what they thought they knew in tatters, with very little to replace it.

Second, is the Western movie genre really so prominent these days that we must combat the pernicious lies of John Wayne and the Lone Ranger? I don’t know about you, but I worry more about my kids picking up myths from Pokemon than from a genre whose popularity dropped off a cliff sometime back in the 80s.

“We are conditioned to think of the loner.” Conditioned. Yes, this man thinks that you have been trained like a dog to salivate at the ringing of a Western-themed bell, the word “loner” popping into your head. The inclusion of random psychology terms where they don’t belong is pseudo-intellectual garbage.

Updated values chart!

The idea of the “loner” cowboy and prospector, even in their mythologized form, is closer to the reality than the picture he draws. On the scale of nations, the US is actually one of the world’s most indivdualist, currently outranked only by Canada, The Netherlands, and Sweden.

Without individualism, you don’t get the notion of private property. In many non-Western societies, land, herds, and other wealth is held collectively by the family or clan, making it nearly impossible for one person (or nuclear family) to cash out his share, buy a wagon, and head West.

I have been reading Horace Kephart’s Our Southern Highlanders, an ethnography of rural Appalachia published in 1913. Here is a bit from the introduction:

The Southern highlands themselves are a mysterious realm. When I prepared, eight years ago, for my first sojourn in the Great Smoky Mountains, which form the master chain of the Appalachian system, I could find in no library a guide to that region. The most diligent research failed to discover so much as a magazine article, written within this generation, that described the land and its people. Nay, there was not even a novel or a story that showed intimate local knowledge. Had I been going to Teneriffe or Timbuctu, the libraries would have furnished information a-plenty; but about this housetop of eastern America they were strangely silent; it was terra incognita.

On the map I could see that the Southern Appalachians cover an area much larger than New England, and that they are nearer the center of our population than any other mountains that deserve the name. Why, then, so little known? …

The Alps and the Rockies, the Pyrennees and the Harz are more familiar to the American people, in print and picture, if not by actual visit, than are the Black, the Balsam, and the Great Smoky Mountains. …For, mark you, nine-tenths of the Appalachian population are a sequestered folk. The typical, the average mountain man prefers his native hills and his primitive ancient ways. …

The mountaineers of the South are marked apart from all other folks by dialect, by customs, by character, by self-conscious isolation. So true is this that they call all outsiders “furriners.” It matters not whether your descent be from Puritan or Cavalier, whether you come from Boston or Chicago, Savannah or New Orleans, in the mountains you are a “furriner.” A traveler, puzzled and scandalized at this, asked a native of the Cumberlands what he would call a “Dutchman or a Dago.” The fellow studied a bit and then replied: “Them’s the outlandish.” …

As a foretaste, in the three and a half miles crossing Little House and Big House mountains, one ascends 2,200 feet, descends 1,400, climbs again 1,600, and goes down 2,000 feet on the far side. Beyond lie steep and narrow ridges athwart the way, paralleling each other like waves at sea. Ten distinct mountain chains are scaled and descended in the next forty miles. …

The only roads follow the beds of tortuous and rock-strewn water courses, which may be nearly dry when you start out in the morning, but within an hour may be raging torrents. There are no bridges. One may ford a dozen times in a mile. A spring “tide” will stop all travel, even from neighbor to neighbor, for a day or two at a time. Buggies and carriages are unheard of. In many districts the only means of transportation is with saddlebags on horseback, or with a “tow sack” afoot. If the pedestrian tries a short-cut he will learn what the natives mean when they say: “Goin’ up, you can might’ nigh stand up straight and bite the ground; goin’ down, a man wants hobnails in the seat of his pants.” …

Such difficulties of intercommunication are enough to explain the isolation of the mountaineers. In the more remote regions this loneliness reaches a degree almost unbelievable. Miss Ellen Semple, in a fine monograph published in[Pg 23] the Geographical Journal, of London, in 1901, gave us some examples:

“These Kentucky mountaineers are not only cut off from the outside world, but they are separated from each other. Each is confined to his own locality, and finds his little world within a radius of a few miles from his cabin. There are many men in these mountains who have never seen a town, or even the poor village that constitutes their county-seat…. The women … are almost as rooted as the trees. We met one woman who, during the twelve years of her married life, had lived only ten miles across the mountain from her own home, but had never in this time been back home to visit her father and mother. Another back in Perry county told me she had never been farther from home than Hazard, the county-seat, which is only six miles distant. Another had never been to the post-office, four miles away; and another had never seen the ford of the Rockcastle River, only two miles from her home, and marked, moreover, by the country store of the district.”

When I first went into the Smokies, I stopped one night in a single-room log cabin, and soon had the good people absorbed in my tales of travel beyond the seas. Finally the housewife said to me, with pathetic resignation: “Bushnell’s the furdest ever I’ve been.” Bushnell, at that time, was a hamlet of thirty people, only seven miles from where we sat. When I lived alone on “the Little Fork of Sugar Fork of[Pg 24] Hazel Creek,” there were women in the neighborhood, young and old, who had never seen a railroad, and men who had never boarded a train, although the Murphy branch ran within sixteen miles of our post-office.

And that’s just Appalachia. What sorts of men and women do you think settled the Rockies or headed to the Yukon? Big, gregarious families that valued their connections to society at large?

Then there are the railroads. The video makes a big deal about the railroads being funded by the government, as proof that Americans weren’t “individuals” but part of some grand collectivist society.

Over in reality, societies with more collectivist values, like Pakistan, don’t undertake big national projects. In those societies, your loyalty is to your clan or kin group, and the operative level of social planning and policy is the clan. Big projects that benefit lots of people, not just particular kin networks, tend not to get funded because people do not see themselves as individuals acting within a larger nation that can do big projects that benefit individual people. Big infrastructure projects, especially in the 1800s, were almost entirely limited to societies with highly individualistic values.

Finally we have the genocide of the American Indians. Yes, some were definitely killed; the past is full of sins. But “You’re wrong, your self-image is wrong, and your ancestors were murderers,” is not a good way to introduce the topic.

It’s a pity the video was not good; the animation was well-done. It turns out that people have far more strident opinions about “Was Westward Expansion Just?” than “Is Pi Irrational?”

I also watched the first episode of Netflix’s new series, The Who Was? Show, based on the popular line of children’s biographies. It was an atrocity, and not just because of the fart jokes. The episode paired Benjamin Franklin and Mahatma Gandhi. Gandhi was depicted respectfully, and as the frequent victim of British racism. Franklin was depicted as a buffoon who hogged the spotlight and tried to steal or take credit for other people’s ideas.

It made me regret buying a biography of Marie Curie last week.

If your children are too young to read first-hand ethnographic accounts of Appalachia and the frontier, what do I recommend instead? Of course there are thousands of quality books out there, and more published every day, but here are a few:

A Child’s Introduction to The World

The Usborne Book of Living Long Ago: Everyday Life Through the Ages

What Your [X] Grader Needs to Know So far I like these, but I have not read them all the way through.

DK: When on Earth?

More important than individual resources, though, is the attitude you bring to the subject.

 

Before we finish, I’d like to note that “America” isn’t actually the society I feel the closest connection to. After all, there are a lot of people here whom I don’t like. The government has a habit of sending loyal citizens to die in stupid wars and denying their medical treatment when they return, and I don’t even know if the country will still exist in meaningful form in 30 years. I think of my society as more “Civilization,” or specifically, “People engaged in the advancement of knowledge.”

Anthropology Friday: Scatalogic Rites of All Nations, pt 3/3

Muslims win this one. Netherlands, on the other hand…

Welcome back to Anthropology Friday. Today we’re finishing up with Bourke’s Scatalogic Rites of All Nations: A dissertation upon the employment of excrementitious remedial agents in religion, therapeutics, divination, witchcraft, love-philters, etc., in all parts of the globe, published in 1891.

This has been an interesting work. Every book is a product of its times, and Bourke’s shows the evidence of multiple schools of thought. You might think, from all of his interest in poop, that he had read Freud’s theories about “anal fixations” and the like, but Bourke predates Freud (Freud’s first major publication, on aphasia, also appeared in 1891, but Totem and Taboo, for example, was not published until 1913.) If anything, perhaps Bourke influenced Freud.

More influential in Bourke’s work is James George Frazer’s The Golden Bough, a work of comparative mythology (which probably also later influenced Campbell’s The Hero with a Thousand Faces,) which itself drew on the general European interest in folklore typified by the Brothers Grimm (early 1800s) and the fraudulent Ossian Epics (late 1700s.) The late 1800s were a time of intense change as the industrial revolution gathered steam, and the notion that ancient, ancestral traditions needed to be recorded and preserved before they were swept away by the changes of the modern era was widespread, prompting both folklorists at home and anthropologists abroad.

At the same time, the proto-Indo-European language had been described in fairly good detail by 1877 (with the publication of August Schleicher‘s A Compendium of the Comparative Grammar of the Indo-European, Sanskrit, Greek and Latin Languages). Here was a successful model of a cultural item (language) evolving (ie, changing) over time that could be used to map the distribution of the people who used it. The idea that things–cultures, people, animals–evolved (or changed) over time was not limited to Darwin–Darwin himself was drawing on the era’s ideas for his unifying theory of evolution via natural selection. Society itself, it seemed, was evolving–and Marx, that voluminous historian of humanity’s changing economic systems and their effects–praised Darwin’s work.

One of the major themes in anthropology at that time was that primitive forms predate modern ones: that is, that modern day primitive people (ie, non-industrialized) preserved the forms of life that the ancestors of industrialized people once followed. So even though you might not be able to figure out much about what pre-literate Europeans believed just by looking at 3,000 year old artifacts, you could infer what their culture was like by just talking to existing pre-literate peoples and looking at what they believe. Marxist theory plays right into this: Marx believed that a culture’s norms and values flowed from its economic system, and thus all hunter-gatherers would share certain norms, and all industrial societies would share certain other norms.

Bourke seeks in his material evidence for something akin to a scatalogical proto-Indo-European, of rites handed down in different location that can be traced back to some ur-rite or ur-belief. He speaks of “survivals,” little customs that might have great antiquity, perhaps dating back to this great ur-culture. For example, he tries to link the Urine Dance of the Zunis to the French Feast of Fools, since both of these involve a mockery of church customs and the eating of something that could loosely be considered excrement, though in the French case it’s just a sausage whose name could be translated as a synonym for excrement. This, he suspects, is a “substitution” of a more palatable item for the older, ancestral form. Already you see the shades of Freud.

He also cites trivial customs like the antics of children at a particular school in Pennsylvania, which seems far more likely to be just “something the kids made up” than a thousand year old “survival” of some ancient custom.

Modern anthropology takes the opposite view (Marxism excluded.) Modern day hunter-gatherers are not seen as models for our own ancestral hunter-gatherers, except in the most minimal sense (obviously they hunted… and gathered. Certain equations about caloric expenditures vs. food acquisition probably hold.) Modern groups are seen not as existing in some kind of “holding pattern” since time immemorial, but as having their own dynamic cultures that have changed (evolved) over time.

There is probably a little truth to both points of view, though thankfully Bourke doesn’t spend too much of the book searching for an ur-scatalogy and gets on with the documentation of various cultural forms, (a task he attacks with encyclopedic thoroughness, often quoting multiple accounts of the same phenomenon and always citing his sources–though I have left out the cites; you can find them in the original if want them):

“As a plaster for the interior of dwellings, cow-dung has been used with frequency ; …

“The natives of the White Nile, the tribes of the Bari, make “a cement of ashes, cow-dung, aud sand,” with which “they plaster the floors and enclosures about their houses.” … Pliny tells us that the threshing-floors of the Roman farmers were paved with cow-dung ; in a footnote it is stated that the same rule obtains in France to this day. …

“Of the Yakuts of Siberia it is related : ” In dirtiness they yield to none ; for a grave author assures us that the mortars which they use for bruising their dried fish are made of cow-dung hardened by the frost.” …

” The people of Jungeiou . . . collected the dung of cows and sheep . . . dried it, roasted it on the fire, and aftewards used it for a bed.” …

” A storekeeper in Berlin was punished some years ago for having used the urine of young girls with a view to make his cheese richer and more piquant. Notwithstanding, people went, bought and ate his cheese with delight. What may be the cause of all these foolish and mysterious things? In human urine is the Anthropin.” — (Per-sonal letter from Dr. Gustav Jseger, Stuttgart, August 29, 1888.)”

EvX: I told you cheese was suspect

“Whether or not the use of humau urine to ripen cheese originated in the ancient practice of employing exerementitious matter to preserve the products of the dairy from the maleficence of witches ; or, on the other hand, whether or not such an employment as an agent to defeat the efforts of the witches be traceable to the fact that stale urine was originally the active ferment to hasten the coagulation of the milk would scarcely be worth discussion. …

“Schurig devotes a chapter to the medicinal preparations made from human ordure. In every case the ordure had to be that of a youth from twenty-five to thirty years old. This manner of preparing chemicals from the human excreta, including phosphorus from urine, was carried to such a pitch that some philosophers believed the philosopher’s stone was to be found by mixing the salts obtained from human urine with those obtained from human excrement. — (See ” Chylologia,” pp. 739-742.) …

“The Eskimo relate stories of a people who preceded them in the Polar regions called the Tornit. Of these predecessors, they say, ” Their way of preparing meat was disgusting, since they let it become putrid, and placed it between the thigh and the belly to warm it.”…

“After describing the double tent of skins used by the Tchuktchees, Mr. W. H. Gilder, author of ” Schwatka’s Search,” says all food is served in the “yoronger,” or inner tent, in which men and women sit, in a state of nudity, wearing only a small loin-cloth of seal-skin.

“After finishing the meal, “a small, shallow pail or pan of wood is passed to any one who feels so inclined, to furnish the warm urine with which the board and knife are washed by the housewife. It is a matter of indifference who furnishes the fluid, whether the men, women, or children ; and I have myself frequently supplied the landlady with the dish-water. In nearly every tent there is kept from the summer season a small supply of dried grass. A little bunch of this is dipped in the warm urine and serves as a dish-rag and a napkin. These people are generally kind and hospitable, and were very attentive to my wants as a stranger, and regarded by them as more helpless than a native.
The women would, therefore, often turn to me after washing the board and knife, and wash my fingers and wipe the grease fro.m my mouth with the moistened grass. Any of the men or women in the tent who desired it would also ask for the wet grass, and use it in the same way.

” It was not done as a ceremony, but merely as a matter of course or of necessity.

” I do not think they would use urine for such purposes if they could get all the water, and especially the warm water, they needed. But all the water they have in winter is obtained by melting snow or ice over an oil lamp, — a very slow process ; and the supply is therefore very limited, being scarcely more than is required for drinking purposes, or to boil such fresh meat as they may have.

” The urine, being warm and containing a small quantity of ammonia, is particularly well adapted for removing grease from the board and utensils, which would otherwise soon become foul, and to their taste much more disagreeable. …

“The manners of the Celtiberians, as described by Strabo and others, have come down through many generations to their descendants in all parts of the world ; all that he related of the use of human urine as a mouth-wash, as a means of ablution, and as a dentifrice, was transplanted to the shores of America by the Spanish colonists ; and even in the present generation, according to Gen. S. V. Benet, U. S. Army, traces of such customs were to be found among some of the settlers in Florida. …

“The smoke and sparks, although sufficiently disagreeable, were trifles of comparative insignificance. I remember being told, in early infancy, that Santa Claus always came into a house through the chimney ; and, although I accepted the statement with the unreasoning faith of childhood, I could never understand how that singular feat of climbing down a chimney could be safely accomplished. . . . My first entrance into a Korak ‘yourt,’ however, at Kamenoi, solved all my childish difficulties, and proved the possibility of entering a house in the eccentric way which Santa Claus is supposed to adopt.” —(George Kennan, “Tent Life in Siberia,” 12th edition, New York, 1887, p. 222.) …

“In Hottentot marriages ” the priest, who lives at the bride’s kraal, enters the circle of the men, and coming up to the bridegroom, pisses a little upon him. The bridegroom receiving the stream with eagerness rubs it all over his body, and makes furrows with his long nails that the urine may penetrate the farther. The priest then goes to the outer circle and evacuates a little upon the bride, who rubs it in with the same eagerness as the bridegroom. To him the priest then returns, and having streamed a little more, goes again to the bride and again scatters his water upon her. Thus he proceeds from one to the other until he has exhausted his whole stock, uttering from time to time to each of
them the following wishes, till he has pronounced the whole upon both: ‘ May you live long and happily together. May you have a son before the end of the year. May this son live to be a comfort to you in your old age. May this son prove to be a man of courage and a good huntsman.'” …

“The attainment by young men of the age of manhood is an event which among all primitive peoples has been signalized by peculiar ceremonies ; in a number of instances ordure and urine have been employed, as for example : The observances connected with this event in the lives of Australian warriors are kept a profound secret, but, among
the few learned is the fact that the neophyte is ” plastered with goat dung.” …

“In order to infuse courage into boys, a warrior, Kerketegerkai, would take the eye and tongue of a dead man (probably of a slain enemy), and after mincing them and mixing with his urine, would administer the compound in the following manner. He would tell the boy to shut his eyes and not look, adding : ‘ I give you proper kaikai ‘ (‘kaikai’ is an introduced word, being the jargon English for food). The warrior then stood up behind the sitting youth, and putting the hitter’s hand between his (the man’s) legs, would feed him. After this dose, ‘heart along, boy no fright.'” — (A. C. Haddou, “The Ethnography of the Western Tribes of Torres Straits,” in Journal of the Anthrop. Institute, Great Britain and Ireland, six. no. 3, 1890, p. 420. …)

“Fearful Rite of the Hottentots:

“A religious rite of still more fearful import occurs among the same people at the initiation of their young men into the rank of warriors — a ceremony which must be deferred until the postulant has attained his eighth or ninth year. It consists, principally, in depriving him of the left testicle, after which the medicine man voids his urine upon
him. …

“Are you aware of the fact that the habit of giving the urine of a healthy child to a new-born babe has prevailed down to the present day among rustic nurses in New England, if not elsewhere, in America? I can bear personal testimony to this fact from absolute knowledge. … (Personal letter from Rev. H. K. Trumbull, editor of the ” Sunday-School Times,” Philadelphia, April 19, 1888.) …

“The reindeer Tchuktchi feign to be passing urine in order to catch their animals which they want to use with their sleds. The reindeer, horses, and cattle of the Siberian tribes are very fond of urine, prob- ably on account of the salt it contains, and when they see a man walking out from the hut, as if for the purpose of relieving his bladder, they follow him up, and so closely that he finds the operation anything but pleasant.

” The Esquimaux of King “William’s Land and the adjacent peninsula often catch the wild reindeer by digging a pit in the deep snow, and covering it with thin blocks of snow, that would break with the weight of an animal. They then make a line of urine from several directions, leading to the centre of the cover of the pitfall, where an accumulation
of snow, saturated with the urine of the dog, is deposited as bait. One or more animals are thereby led to their destruction.” …

“A PARSI is defiled by touching a corpse. “And when he is in contact and does not move it, he is to be washed with bull’s urine and water.”…

“In the cremation of a Hindu corpse at Bombay, the ashes of the pyre were sprinkled with water, a cake of cow-dung placed in the centre, and around it a small stream of cow-urine ; upon this were
placed plantain-leaves, rice-cakes, and flowers. …

“The Creation Myth of the Australians relates that the god Bund-jil created the ocean by urinating for many days upon the orb of the earth. …

“In the cosmogonical myths of the islanders of Kadiack, it is related that the first woman, ” by making water, produced seas.”

North Africa in Genetics and History

detailed map of African and Middle Eastern ethnicities in Haaks et al’s dataset

North Africa is an often misunderstood region in human genetics. Since it is in Africa, people often assume that it contains the same variety of people referenced in terms like “African Americans,” “black Africans,” or even just “Africans.” In reality, the African content contains members of all three of the great human clades–Sub-Saharan Africans in the south, Polynesians (Asian clade) in Madagascar, and Caucasians in the north.

The North African Middle Stone Age and its place in recent human evolution provides an overview of the first 275,000 years of humanity’s history in the region(300,000-25,000 years ago, more or less), including the development of symbolic culture and early human dispersal. Unfortunately the paper is paywalled.

Throughout most of human history, the Sahara–not the Mediterranean or Red seas–has been the biggest local impediment to human migration–thus North Africans are much closer, genetically, to their neighbors in Europe and the Middle East than their neighbors across the desert (and before the domestication of the camel, about 3,000 years ago, the Sahara was even harder to cross.)

But from time to time, global weather patterns change and the Sahara becomes a garden: the Green Sahara. The last time we had a Green Sahara was about 9-7,000 years ago; during this time, people lived, hunted, fished, herded and perhaps farmed throughout areas that are today nearly uninhabited wastes.

The Peopling of the last Green Sahara revealed by high-coverage resequencing of trans-Saharan patrilineages sheds light on how the Green (and subsequently brown) Sahara affected the spread (and separation) of African groups into northern and sub-Saharan:

In order to investigate the role of the last Green Sahara in the peopling of Africa, we deep-sequence the whole non-repetitive portion of the Y chromosome in 104 males selected as representative of haplogroups which are currently found to the north and to the south of the Sahara. … We find that the coalescence age of the trans-Saharan haplogroups dates back to the last Green Sahara, while most northern African or sub-Saharan clades expanded locally in the subsequent arid phase. …

Our findings suggest that the Green Sahara promoted human movements and demographic expansions, possibly linked to the adoption of pastoralism. Comparing our results with previously reported genome-wide data, we also find evidence for a sex-biased sub-Saharan contribution to northern Africans, suggesting that historical events such as the trans-Saharan slave trade mainly contributed to the mtDNA and autosomal gene pool, whereas the northern African paternal gene pool was mainly shaped by more ancient events.

In other words, modern North Africans have some maternal (female) Sub-Saharan DNA that arrived recently via the Islamic slave trade, but most of their Sub-Saharan Y-DNA (male) is much older, hailing from the last time the Sahara was easy to cross.

Note that not much DNA is shared across the Sahara:

After the African humid period, the climatic conditions became rapidly hyper-arid and the Green Sahara was replaced by the desert, which acted as a strong geographic barrier against human movements between northern and sub-Saharan Africa.

A consequence of this is that there is a strong differentiation in the Y chromosome haplogroup composition between the northern and sub-Saharan regions of the African continent. In the northern area, the predominant Y lineages are J-M267 and E-M81, with the former being linked to the Neolithic expansion in the Near East and the latter reaching frequencies as high as 80 % in some north-western populations as a consequence of a very recent local demographic expansion [810]. On the contrary, sub-Saharan Africa is characterised by a completely different genetic landscape, with lineages within E-M2 and haplogroup B comprising most of the Y chromosomes. In most regions of sub-Saharan Africa, the observed haplogroup distribution has been linked to the recent (~ 3 kya) demic diffusion of Bantu agriculturalists, which brought E-M2 sub-clades from central Africa to the East and to the South [1117]. On the contrary, the sub-Saharan distribution of B-M150 seems to have more ancient origins, since its internal lineages are present in both Bantu farmers and non-Bantu hunter-gatherers and coalesce long before the Bantu expansion [1820].

In spite of their genetic differentiation, however, northern and sub-Saharan Africa share at least four patrilineages at different frequencies, namely A3-M13, E-M2, E-M78 and R-V88.

A recent article in Nature, “Whole Y-chromosome sequences reveal an extremely recent origin of the most common North African paternal lineage E-M183 (M81),” tells some of North Africa’s fascinating story:

Here, by using whole Y chromosome sequences, we intend to shed some light on the historical and demographic processes that modelled the genetic landscape of North Africa. Previous studies suggested that the strategic location of North Africa, separated from Europe by the Mediterranean Sea, from the rest of the African continent by the Sahara Desert and limited to the East by the Arabian Peninsula, has shaped the genetic complexity of current North Africans15,16,17. Early modern humans arrived in North Africa 190–140 kya (thousand years ago)18, and several cultures settled in the area before the Holocene. In fact, a previous study by Henn et al.19 identified a gradient of likely autochthonous North African ancestry, probably derived from an ancient “back-to-Africa” gene flow prior to the Holocene (12 kya). In historic times, North Africa has been populated successively by different groups, including Phoenicians, Romans, Vandals and Byzantines. The most important human settlement in North Africa was conducted by the Arabs by the end of the 7th century. Recent studies have demonstrated the complexity of human migrations in the area, resulting from an amalgam of ancestral components in North African groups15,20.

According to the article, E-M81 is dominant in Northwest Africa and absent almost everywhere else in the world.

The authors tested various men across north Africa in order to draw up a phylogenic tree of the branching of E-M183:

The distribution of each subhaplogroup within E-M183 can be observed in Table 1 and Fig. 2. Indeed, different populations present different subhaplogroup compositions. For example, whereas in Morocco almost all subhaplogorups are present, Western Sahara shows a very homogeneous pattern with only E-SM001 and E-Z5009 being represented. A similar picture to that of Western Sahara is shown by the Reguibates from Algeria, which contrast sharply with the Algerians from Oran, which showed a high diversity of haplogroups. It is also worth to notice that a slightly different pattern could be appreciated in coastal populations when compared with more inland territories (Western Sahara, Algerian Reguibates).

Overall, the authors found that the haplotypes were “strikingly similar” to each other and showed little geographic structure besides the coastal/inland differences:

As proposed by Larmuseau et al.25, the scenario that better explains Y-STR haplotype similarity within a particular haplogroup is a recent and rapid radiation of subhaplogroups. Although the dating of this lineage has been controversial, with dates proposed ranging from Paleolithic to Neolithic and to more recent times17,22,28, our results suggested that the origin of E-M183 is much more recent than was previously thought. … In addition to the recent radiation suggested by the high haplotype resemblance, the pattern showed by E-M183 imply that subhaplogroups originated within a relatively short time period, in a burst similar to those happening in many Y-chromosome haplogroups23.

In other words, someone went a-conquering.

Alternatively, given the high frequency of E-M183 in the Maghreb, a local origin of E-M183 in NW Africa could be envisaged, which would fit the clear pattern of longitudinal isolation by distance reported in genome-wide studies15,20. Moreover, the presence of autochthonous North African E-M81 lineages in the indigenous population of the Canary Islands, strongly points to North Africa as the most probable origin of the Guanche ancestors29. This, together with the fact that the oldest indigenous inviduals have been dated 2210 ± 60 ya, supports a local origin of E-M183 in NW Africa. Within this scenario, it is also worth to mention that the paternal lineage of an early Neolithic Moroccan individual appeared to be distantly related to the typically North African E-M81 haplogroup30, suggesting again a NW African origin of E-M183. A local origin of E-M183 in NW Africa > 2200 ya is supported by our TMRCA estimates, which can be taken as 2,000–3,000, depending on the data, methods, and mutation rates used.

However, the authors also note that they can’t rule out a Middle Eastern origin for the haplogroup since their study simply doesn’t include genomes from Middle Eastern individuals. They rule out a spread during the Neolithic expansion (too early) but not the Islamic expansion (“an extensive, male-biased Near Eastern admixture event is registered ~1300 ya, coincidental with the Arab expansion20.”) Alternatively, they suggest E-M183 might have expanded near the end of the third Punic War. Sure, Carthage (in Tunisia) was defeated by the Romans, but the era was otherwise one of great North African wealth and prosperity.

 

Interesting papers! My hat’s off to the authors. I hope you enjoyed them and get a chance to RTWT.
