Addendum to Race: The Social Construction of a Biological Reality

Now I am going to try to express a bit of nuance, staking out a position somewhere between “race isn’t real” and “Derbyshire is a race traitor.”

In the “race isn’t real” department, we have Sarah Zhang’ Will the Alt-Right Promote a New Kind of Racist Genetics?:

In the genomic age, it is now easy to compare the DNA of people from around the world. And it has indeed revealed that our racial categories are fuzzy proxies for genetic difference—an African man may be more closely related to an Asian than to another African.

From there, Zhang basically tries to argue that race doesn’t real even though genetics and medical science sure make it look real, that the differences in the distribution of genetic traits in large, historically isolated populations don’t matter because of a few tiny populations that are the genetic equivalent of the Basque language.

Remember, the world’s entire population of Bushmen wouldn’t even fill the Texas A&M football stadium. Combine them with a few other tiny populations, like the Khoikhoi and Pygmies, and you’re still looking at <1 million people.  Meanwhile, there are billions of Europeans, west Africans, and east Asians.

Mundane racial categories work just fine for the vast majority of people, including the vast majority of Americans, who are not drawn from a rainbow of racially-mixed groups like Tuaregs or fringe outliers like the Bushmen, but from distinct populations of West Africans, Europeans (primarily NW Euros,) Native Americans, and East Asians. If I say someone is “black” or “white,” not only do you understand what I mean, there is an actually consistent genetic reality underlying my statements–in almost 100% of cases, a genetic test would in fact confirm that the people I call “black” are actually primarily Sub-Saharan African by ancestry and the people I call “white” are primarily European by ancestry. Exceptions like Rachel Dolezal are quite rare.

Zhang is trying to argue that you can’t make a reasonable argument about the average distribution of traits between whites, blacks, and Asians in the US because there is a handful of tiny, genetically isolated populations over in Africa. A does not follow from B.

On the other side of the coin, we have people who believe it’s morally imperative to only marry people from one’s own race.

Most of the time, people fall in love with people from their own culture and ethnic group. This is what we’d expect, because you’re more likely to meet and share values with people from your own group. (Interestingly, most people are more genetically similar to their spouses than they are to the average person in their community, not because they married a close relative, but because similar genes make for similar people.)

But some people, for whatever reasons, marrying within their own group isn’t a real option. (White men who are under 5’5″, for example.) These people are looking out for their own best interests–really, if you’re considering calling Derbyshire a race traitor, you’re probably thinking too much about other people’s business.

Capitalism works because it self-corrects; it allows consumers to pick the best products at the best prices, and companies to hire the most talented workers for the best wages. Unlike socialism, where companies are told what and how much to produce, consumers are told what to buy and how much it will cost, and ultimately people starve in the streets, capitalism actually works. Self-interest is a powerful organizing principle that has radically increased the welfare of billions of people over the past century.

And capitalism doesn’t care about race.

Where people live in close proximity to people of other races, some of them will fall in love.

That said, don’t date people for status points or because you’re trying to prove how not-racist you are. Like Obama’s parents, most inter-racial couples don’t stay together; the majority of mixed-race children have parents who are not married–according to one study, 92% of biracial children with black fathers are born out of wedlock and 82% end up on government assistance because their fathers do not bother to take care of them.

picture-6And if you are ever tempted to compare your vagina to the UN because of the sheer number of different ethnicities that have been in it, you need to stop and re-evaluate your life for multiple reasons.

 

Ultimately, real-life decisions should be based on real-life concerns.

Wed Open Thread: 770,000 genomes and the American Nations

Wow, is it Wednesday already? Time definitely flies when you’re busy.

In interesting news, Politico ran an article with a long (and somewhat misleading) section about Moldbug, and further alleging (based on unnamed “sources” who are probably GodfreyElfwick again*,) that Moldbug is in communication with the Trump Administration:

In one January 2008 post, titled “How I stopped believing in democracy,” he decries the “Georgetownist worldview” of elites like the late diplomat George Kennan. Moldbug’s writings, coming amid the failure of the U.S. state-building project in Iraq, are hard to parse clearly and are open to multiple interpretations, but the author seems aware that his views are provocative. “It’s been a while since I posted anything really controversial and offensive here,” he begins in a July 25, 2007, post explaining why he associates democracy with “war, tyranny, destruction and poverty.”

Moldbug, who does not do interviews and could not be reached for this story, has reportedly opened up a line to the White House, communicating with Bannon and his aides through an intermediary, according to a source. Yarvin said he has never spoken with Bannon.

Vox does a much longer hit piece on Moldbug, just to make sure you understand that they really, truly don’t approve of him, then provides more detail on Moldbug’s denial:

The idea that I’m “communicating” with Steve Bannon through an “intermediary” is preposterous. I have never met Steve Bannon or communicated with him, directly or indirectly. You might as well accuse the Obama administration of being run by a schizophrenic homeless person in Dupont Circle, because he tapes his mimeographed screeds to light poles where Valerie Jarrett can read them.

*In all fairness, there was a comment over on Jim’s Blog to the effect that there is some orthosphere-aligned person in contact with the Trump administration, which may have set off a chain of speculation that ended with someone claiming they had totally legit sources saying Moldbug was in contact with Bannon.

In other news, Han et al have released Clustering of 770,000 genomes reveals post-colonial population structure of North America:

Here we identify very recent fine-scale population structure in North America from a network of over 500 million genetic (identity-by-descent, IBD) connections among 770,000 genotyped individuals of US origin. We detect densely connected clusters within the network and annotate these clusters using a database of over 20 million genealogical records. Recent population patterns captured by IBD clustering include immigrants such as Scandinavians and French Canadians; groups with continental admixture such as Puerto Ricans; settlers such as the Amish and Appalachians who experienced geographic or cultural isolation; and broad historical trends, including reduced north-south gene flow. Our results yield a detailed historical portrait of North America after European settlement and support substantial genetic heterogeneity in the United States beyond that uncovered by previous studies.

Wow! (I am tempted to add “just wow.”) They have created a couple of amazing maps:

Comment of the Week goes to Tim Smithers for his contributions on IQ in Are the Pygmies Retarded:

IQ generally measures the ability to learn, retain information, and make logical decisions and conclusions. It is not about mathematics nor reading, at least in modern testing (since about 1980).
Modern IQ tests typically do not have any math or even reading. Many have no verbiage at all, and there is no knowledge of math required in the least.
For example, a non-verbal, non-math IQ test may have a question that shows arrows pointing in different directions. The test taker must identify which direction would make the most sense for the next arrow to go.
I’m very sorry to disappoint, but I’ve done considerable research into IQ testing over the past decade. The tests have had cultural biases removed (including the assumption that one can read) in order to assess a persons ability to learn, to retain information, and to use common logic. …

You may, of course, RTWT there.

So, how’s it going out there?

 

Race: The social construction of biological reality, pt 3

Oh man! We are finally at part three! The part in which I attempt incorporating two-D space into our diagram:

race3

Right, so as we turn our car around and head back up the road, we notice an intriguing turnoff in the Congolese rainforest: a tribe of the shortest people in the world, the Pygmies. According to Wikipedia:

A pygmy is a member of an ethnic group whose average height is unusually short; anthropologists define pygmy as a member of any group where adult men are on average less than 150 cm (4 feet 11 inches) tall.[1] A member of a slightly taller group is termed “pygmoid“.[2]

The term is most associated with peoples of Central Africa, such as the Aka, Efé and Mbuti.[3] If the term pygmy is defined as a group’s men having an average height below 1.55 meters (5 feet 1 inch), then there are also pygmies in Australia, Thailand, Malaysia, the Andaman Islands,[4] Indonesia, the Philippines, Papua New Guinea, Bolivia, and Brazil,[5] including some Negritos of Southeast Asia.

Women of the Batwa Pygmies
Women of the Batwa Pygmies

Basically, whenever humans live in tropical rainforests, there’s a good chance they’ll get shorter. (Rainforests also produce pygmy elephants.) Maybe it’s because short people can move more easily through the dense forest, or an adaptation to low levels of iodine, sunlight, or other nutrients–I don’t really know.

Wikipedia estimates that there are between 250,000 and 600,000 pygmies living in the Congo rainforest:

Genetically, the pygmies are extremely divergent from all other human populations, suggesting they have an ancient indigenous lineage. Their uniparental markers represent the most ancient divergent ones right after those typically found in Khoisan peoples. African pygmy populations possess high levels of genetic diversity,[10] recent advances in genetics shed some light on the origins of the various pygmy groups. …

“We studied the branching history of Pygmy hunter–gatherers and agricultural populations from Africa and estimated separation times and gene flow between these populations. The model identified included the early divergence of the ancestors of Pygmy hunter–gatherers and farming populations ~60,000 years ago, followed by a split of the Pygmies’ ancestors into the Western and Eastern Pygmy groups ~20,000 years ago.”

But I recall–was it WestHunt?–objecting that the authors of this paper used a too-fast estimation of genetic mutation rates. Oh here it is:

There are a couple of recent papers on introgression from some quite divergent archaic population into Pygmies ( this also looks to be the case with Bushmen). Among other things, one of those papers discussed the time of the split between African farmers (Bantu) and Pygmies, as determined from whole-genome analysis and the mutation rate. They preferred to use the once-fashionable rate of 2.5 x 10-8 per-site per-generation (based on nothing), instead of the new pedigree-based estimate of about 1.2 x 10-8 (based on sequencing parents and child: new stuff in the kid is mutation). The old fast rate indicates that the split between Neanderthals and modern humans is much more recent than the age of early Neanderthal-looking skeletons, while the new slow rate fits the fossil record – so what’s to like about the fast rate? Thing is, using the slow rate, the split time between Pygmies and Bantu is ~300k years ago – long before any archaeological sign of behavioral modernity (however you define it) and well before the first known fossils of AMH (although that shouldn’t bother anyone, considering the raggedness of the fossil record).

See my review of Isaac Bacirongo and Nest's Still a Pygmy
See my review of Isaac Bacirongo and Michael Nest’s Still a Pygmy

Let’s split the difference and say that one way or another, Pygmies split off from their hunter-gatherer neighbors and became isolated in the rainforest quite a while ago.

Before we drive on, I’d like to pause and note that I’m not entirely comfortable with using the way Pygmies are sometimes used in racial discussions. Yes, they are short, but they otherwise look a lot like everyone else in the area. Pygmies go to school, often speak multiple languages, live in cities, work at real jobs, read books, operate businesses, drive cars, fall in love, get married, build houses, etc. For more on Pygmies see my review of Isaac Bacirongo’s memoir Still a Pygmy (Isaac is a Pygmy man who speaks, IIRC, 5 languagues, attended highschool, and owned/ran successful pharmacies in two different cities in the DRC before the army burned them down during a civil war.)

Now I admit that Isaac is just one guy and I don’t know what the rest of the Pygmies are like.

People over-thought ancestry long before 23 and Me
Different classes of Mexican mestizos: people over-thought ancestry long before 23 and Me

But let’s hop back in our car, for at the other end of this road we have not a small town of isolated forest-dwellers, but a large group we have so far neglected: the Native Americans.

The indigenous peoples of North and South America today number about 60 million people, plus some quantity of mixed-race people (mestizos.) In some areas these mestizos are majority European by ancestry; in others they are majority Indian; studies in Mexico, for example, estimate that 80-93% of the population is Mestizo, with Indian ancestry averaging between 31% and 66% in different regions. The people of El Salvador are about 86% mestizo; Chileans are about 40% Indian and 60% Europeans; Columbia is about 49% mestizo; etc.

Unfortunately, Wikipedia doesn’t list the total number of mestizos, and I don’t have time to calculate it, but I will note that the total population of both continents, including Canada and the USA, is about 1 billion people.

We’re not sure exactly when (or how) the Indians got here, but it looks like they arrived around 10-20,000 years ago across the then-Bering Landbridge. (I think we should also keep in mind the possibility that they could have built boats.) According to Wikipedia:

Scientific evidence links indigenous Americans to Asian peoples, specifically Siberian populations, such as the Ket, Selkup, Chukchi and Koryak peoples. Indigenous peoples of the Americas have been linked to North Asian populations by the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA.[192] There is general agreement among anthropologists that the source populations for the migration into the Americas originated from an area somewhere east of the Yenisei River. The common occurrence of the mtDNA Haplogroups A, B, C, and D among eastern Asian and Native American populations has long been recognized.[193] As a whole, the greatest frequency of the four Native American associated haplogroups occurs in the AltaiBaikal region of southern Siberia.[194] Some subclades of C and D closer to the Native American subclades occur among Mongolian, Amur, Japanese, Korean, and Ainu populations.[193][195]

Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically close to Amerindians.[citation needed] This view is shared by other researchers who argue that “the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic.”[196][197] 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis.[198] The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%;[199][200][201] xQ1a 4-32%[199][200]).

These ancient Siberians also had some “European” DNA, as do modern Siberians, but they are most closely related to their neighbors to the south, throughout the rest of Asia. Native American DNA is super fascinating, but we don’t have time to get into it all. On the grand scale, Native Americans are genetically Asians, separated from the rest of the clade by (probably) a mere 13-20,000 years. (Somewhat coincidentally, the Dire wolf, Smilodon, giant beaver, ground sloth, giant Columbian mammoth (Mammuthus columbi), woolly mammoth, mastodons, giant short-faced bear, American cheetah, scimitar cats (Homotherium), American camels, American horses, and American lions all went extinct in North America around 12,000 years ago.)

On the grand scale of human history, (200,000 years, more or less,) 13-20,000 years is not very long, and the Native Americans have not diverged too much, physically, from their cousins in Asia. The G-allele mutation of the EDAR gene arose about 30,000 years ago somewhere in east Asia and gives both modern Asians and Native Americans (but not Europeans and Africans) their characteristic hair and skin tone. While Native Americans are clearly physically, culturally, and geographically distinct from other Asians, (just as Europeans and south-Asian Indians are distinct from each other,) they are genetically close enough that they unquestionably clade together in the greater racial schema.

As I’ve said before, my diagram is just one way to represent one aspect of the genetic (and physical) distances between people.

Here is another diagram, not mine, which tells the same story in a different way (though it estimates a much lower genetic distance between Bushmen and Bantus than I’d expect. Oh well. different studies get different results; that’s why replication and meta-analysis are super important):

The Melanesians of Papua New Guinea and Australia are in pink (there are some mixed Melanesian / Polynesian populations in the world, but our road trip skipped them.) Their nearest relatives are other south Asians and Polynesians, but those same south Asians are themselves more closely related to Europeans than Australians. Diagrammed like this, it’d be understandable to break off south Asians into one race and put Caucasians, Native Americans, and East Asians into a single race. And I suppose you could, if you wanted to and could get everyone else to start using your categories. Race is biologically real and quite obvious at the macro scale, but a few small groups like Aborigines and Bushmen introduce existential uncertainty that intellectuals can quibble over.I don’t think it would be terribly useful rearrangement, though, for all of the reasons discussed over the past three posts in this series.

Well, that’s the end of our big road trip! I hope you’ve enjoyed it, and that it’s cleared up that nagging question people seem to have: How can Nigerians be more closely related to Europeans than some other Africans? Have a great day, and enjoy the drive home.

Race: The Social Construction of a Biological Reality, pt 2

Note: This post still contains a lot of oversimplification for the sake of explaining a few things.

Welcome back to our discussion of the geographic dispersion of humanity. On Tuesday, we discussed how two great barriers–the Sahara desert and the Himalayas + central Asian desert–have impeded human travelers over the millennia, resulting in three large, fairly well-defined groups of humans, the major races: Sub-Saharan Africans (SSA), Caucasians, and east Asians.

Of course, any astute motorist, having come to a halt at the Asian end of our highway, might observe that there is, in fact, a great deal of land in the world that we have not yet explored. So we head to the local shop and pick up a better map:

race2

Our new map shows us navigational directions for getting to Melanesia and Australia–in ice age times, it instructs us, we can drive most of the way. If there isn’t an ice age, we’ll have to take a boat.

900px-oceania_un_geoscheme_-_map_of_melanesia-svgThe people of Melanesia and Australia are related, the descendants of one of the first groups of humans to split off from the greater tribe that left Africa some 70k ago.

As the name “Melanesian” implies, they are quite dark-skinned–a result of never having ventured far from the equatorial zone.

Today, they live in eastern Indonesia, Papua New Guinea, Australia, and a smattering of smaller islands. (Notably, the Maori of New Zealand are Polynesians like the Hawaiians, not Melanesians, descendants of a different migration wave that originated in Taiwan.)

Fijian mountain warrior

There is some speculation that they might have once been wider-spread than they currently are, or that various south-Asian tribes might be related to them, (eg, “A 2009 genetic study in India found similarities among Indian archaic populations and Aboriginal people, indicating a Southern migration route, with expanding populations from Southeast Asia migrating to Indonesia and Australia,”) but I don’t think any mainland group would today be classed as majority Melanesian by DNA.

They may also be related to the scattered tribes of similarly dark-skinned, diminutive people known as the Negritos:

Males from the Aeta people (or Agta) people of The Philippines, are of great interest to genetic, anthropological and historical researchers, as at least 83% of them belong to haplogroup K2b, in the form of its rare primary clades K2b1* and P* (a.k.a. K2b2* or P-P295*).[7] Most Aeta males (60%) carry K-P397 (K2b1), which is otherwise uncommon in the Philippines and is strongly associated with the indigenous peoples of Melanesia and Micronesia. Basal P* is rare outside the Aeta and some other groups within Maritime South East Asia. …

Naural blond hair
Two Melanesian girls from Vanatu (blond hair is common in Melanesian children.)

A 2010 study by the Anthropological Survey of India and the Texas-based Southwest Foundation for Biomedical Research identified seven genomes from 26 isolated “relic tribes” from the Indian mainland, such as the Baiga, which share “two synonymous polymorphisms with the M42 haplogroup, which is specific to Australian Aborigines“. These were specific mtDNA mutations that are shared exclusively by Australian aborigines and these Indian tribes, and no other known human groupings.[12]

A study of blood groups and proteins in the 1950s suggested that the Andamanese were more closely related to Oceanic peoples than African Pygmies. Genetic studies on Philippine Negritos, based on polymorphic blood enzymes and antigens, showed they were similar to surrounding Asian populations.[13]

Negrito peoples may descend from Australoid Melanesian settlers of Southeast Asia. Despite being isolated, the different peoples do share genetic similarities with their neighboring populations.[13][14] They also show relevant phenotypic (anatomic) variations which require explanation.[14]

In contrast, a recent genetic study found that unlike other early groups in Malesia, Andamanese Negritos lack the Denisovan hominin admixture in their DNA. Denisovan ancestry is found among indigenous Melanesian and Australian populations between 4–6%.[15][16]

Australian Aboriginal man
Australian Aboriginal man

However, the Negritos are a very small set of tribes, and I am not confident that they are even significantly related to each other, rather than just some short folks living on a few scattered islands. We must leave them for another day.

The vast majority of Aborigines and Melanesians live in Australia, Papua New Guinea, and nearby islands. They resemble Africans, because they split off from the rest of the out-of-Africa crew long before the traits we now associate with “whites” and “Asians” evolved, and have since stayed near the equator, but they are most closely related to–sharing DNA with–south Asians (and Indians.)

So we have, here, on the genetic level, a funny situation. Melanesians are–relatively speaking–a small group. According to Wikipedia, thee are about 12 million Melanesians and 606,000 Aborigines. By contrast, Tokyo prefecture has 13 million people and the total Tokyo metro area has nearly 38 million. Meanwhile, the Han Chinese–not a race but a single, fairly homogenous ethnic group–number around 1.3 billion.

Of all the world’s peoples, Melanesians/Aborigines are most closely related to other Asians–but this is a distant relationship, and those same Asians are more closely related to Caucasians than to Aborigines.

As I mentioned on Tuesday, the diagram, because it is 1-dimensional, can only show the distance between two groups at a time, not all groups. The genetic distance between Caucasians and Aborigines is about 60 or 50k, while the distance between Asians and Caucasians is around 40k, but the distance between Sub-Saharan Africans and ALL non-SSAs is about 70k, whether they’re in Australia, Patagonia, or France. Our map is not designed to show this distance, only the distances between individual pairs.

Some anthropologists refer to Bushmen as "gracile," which means they are a little shorter than average Europeans and not stockily built
Some anthropologists refer to Bushmen as “gracile,” which means they are a little shorter than average Europeans and not stockily built

Now if we hopped back in our car and zoomed back to the beginning of our trip, pausing to refuel in Lagos, we’d note another small group that has been added to the other end of the map: the Bushmen, aka the Khoi-San people. Wikipedia estimates 90,000 San and doesn’t give an estimate for the Khoi people, but their largest group, the Nama, has about 200,000 people. We’ll estimate the total, therefore, around 500,000 people, just to be safe.

The Bushmen are famous for being among the world’s last hunter-gatherers; their cousins the Khoi people are pastoralists. There were undoubtedly more of them in the past, before both Europeans and Bantus arrived in southern Africa. Some people think Bushmen look a little Asian, due to their lighter complexions than their more equatorial African cousins.

Genetically:

Various Y chromosome studies show that the San carry some of the most divergent (oldest) human Y-chromosome haplogroups. These haplogroups are specific sub-groups of haplogroups A and B, the two earliest branches on the human Y-chromosome tree.[48][49][50]

Mitochondrial DNA studies also provide evidence that the San carry high frequencies of the earliest haplogroup branches in the human mitochondrial DNA tree. This DNA is inherited only from one’s mother. The most divergent (oldest) mitochondrial haplogroup, L0d, has been identified at its highest frequencies in the southern African San groups.[48][51][52][53]

I loved that movie
The late Nǃxau ǂToma, (aka Gcao Tekene Coma,) Bushman star of “The Gods Must be Crazy,” roughly 1944-2003

In a study published in March 2011, Brenna Henn and colleagues found that the ǂKhomani San, as well as the Sandawe and Hadza peoples of Tanzania, were the most genetically diverse of any living humans studied. This high degree of genetic diversity hints at the origin of anatomically modern humans.[54][55]

Recent analysis suggests that the San may have been isolated from other original ancestral groups for as much as 100,000 years and later rejoined, re-integrating the human gene pool.[56]

A DNA study of fully sequenced genomes, published in September 2016, showed that the ancestors of today’s San hunter-gatherers began to diverge from other human populations in Africa about 200,000 years ago and were fully isolated by 100,000 years ago … [57]

So the total distance between Nigerians and Australian Aborogines is 70k years; the distance between Nigerians and Bushmen is at least 100k years.

When we zoom in on the big three–Sub-Saharan Africans, Caucasians, and Asians–they clade quite easily and obviously into three races. But when we add Aborigines and Bushmen, things complicate. Should we have a “race” smaller than the average American city? Or should we just lump them in with their nearest neighbors–Bushmen with Bantus and Aborigines with Asians?

I am fine with doing both, actually–but wait, I’m not done complicating matters! Tune in on Monday for more.

Race: The Social Construction of Biological Reality

Note: This post contains a lot of oversimplification for the sake of explaining a few things. (Yes, I am still meditating on the greater Asian clade.)

Imagine you’re driving down a long highway that stretches from Nigeria to Beijing, passing through Berlin and New Delhi. In reality this route takes some large twists and turns, but we’re drawing it as a straight line, for all maps must simplify to be useful.

As you drive along, you pass many houses along the way–sometimes just a few clustered next to the highway, sometimes small towns, sometimes megalopolises with billions of people.

race

Our drive begins in one such megalopolis, that of Sub-Saharan Africa (SSA.) Here we meet people like Queen Anna Nzinga, author Chinua Achebe, and–though they have traveled far abroad–African Americans like Oprah Winfrey and Martin Luther King.

Though thousands of different languages are spoken by the thousands of different groups throughout SSA, we may still note a certain physical similarity among them–dark skin perfectly adapted to the equator’s strong sun, dark eyes, and tightly curling hair. While there is a tremendous amount of variety here–probably the most of any megalopolis in the world–they are also, quite clearly, related. You don’t have to go measuring skulls to figure that out.

But as we drive north, the houses thin out. Suddenly we are in a zone with almost no people–an enormous desert: the Sahara.

We speed through this harsh, empty landscape on a starry night, spotting only a few camels in the distance. We’re lucky we have a full tank of gas and several more in the trunk–for all but the most intrepid of our pre-automobile ancestors, this desert was nigh impassible, a vast barrier to human movement.

Finally we reach the vast inland sea of the Mediterranean, and the beginning of our second megalopolis. Most of the people here, from Berbers to Egyptians, have their own distinct look, more similar to their neighbors from the Middle East and Southern Europe than their neighbors to the south, across the inhospitable expanse of sand.

While there are many different countries and languages, no clear phenotypic line separates the people of Northern Africa, the Middle East, southern Europe, or northern Europe. Skin pales, hair lightens and becomes wavy, eyes turn a variety of hues as one nationality melts into the next. North-central Europe is the only place in the world where blue/green/hazel eyes and blond hair are common in adults; even in Wales, dark hair is dominant.

We hang a right through Turkey, Iran, Pakistan, and India, teeming with people.  Here again, though the people change and there are barriers like the Thar Desert, we find no harsh, nigh-impenetarable breaks like the Sahara.

Then, suddenly, we run smack into a wall, a natural wall of majestic proportions: the Himalayas. Beyond lie the Tibetan Plateau, Gobi Desert, and the vast emptiness of the Asian steppe. If this land was ever densely populated, generations of marauding steppe warriors have wiped them out. We see a few people here–aptly named Tibetan lamas, flocks of sheep grazing beside a scattering of yurts. Mongolia holds the distinction of being the world’s least densely populated independent country. (Ice-covered Greenland is even less dense, but owned by Denmark.)

Finally we pass beyond the shadow of the Great Khan’s memorial and into the valley of the Yellow River, where we find our third megalopolis: east Asia.

There is notably less genetic diversity here than in the first megalopolis–indeed, 93% of Han Chinese share a particular variety of the EDAR allele:

A derived G-allele point mutation (SNP) with pleiotropic effects in EDAR, 370A or rs3827760, found in most modern East Asians and Native Americans but not common in African or European populations, is thought to be one of the key genes responsible for a number of differences between these populations, including the thicker hair, more numerous sweat glands, smaller breasts, and dentition characteristic of East Asians.[7] … The 370A mutation arose in humans approximately 30,000 years ago, and now is found in 93% of Han Chinese and in the majority of people in nearby Asian populations.

Here, too, skin tones vary from north to south, though not as greatly as they do closer to the Greenwich Meridian. Most people have dark eyes, slim frames, and straight, smooth black hair.

Here in the megalopolis made famous by Beijing, Shanghai, Hong Kong, Seoul, and Tokyo, we have come to the end of the–first round–of our journey. From Africa to Asia, we have found three vast areas filled with people, and two major barriers which–though not completely impassible–have hindered humanity’s footsteps over the millennia.

People sometimes try to claim that human races do not exist simply because edge cases exist, small, scattered groups which possess a mixture of genes common to both Sub-Saharan Africans and Caucasians, Caucasians and Asians. And these groups do in fact exist, and are fascinating in their own rights. But these groups are also small, often living in extremely harsh, forbidding lands where few humans can survive (The inhabitants of the Himalayas and Tibetan plateau, I note, actually carry a gene that helps them survive at high altitudes which they received via an ancestor’s dalliance with a Denisovan hominin–the Denisovans were cousin to the Neanderthals and lived in Asia long before Homo Sapiens. No one else in the world carries this gene, so if you don’t have it, good luck living up there!)

But the vast, vast majority of the world’s people do not live in these harsh and unforgiving lands. They live clustered together in the enormous population centers, continually mixing, migrating, churning, and conquering each other, not people thousands of miles off. The concept of race stems from this basic observation of the geography of human settlements.

Physical distance is genetic distance, but since my diagram is only two-dimensional, it can only show the genetic distance between two points at a time. The genetic distance between Asians and Caucasians is about 40k years–much shorter than the distance between Sub-Saharan Africans and Caucasians, 70k years. But the distance between Sub-Saharan Africans and Asians is also about 70k years. Although Asians and Caucasians split apart from each other about 40,000 years ago, they are both descended from a single group of ancestors (a handful of Denisovans and Neanderthals excluded) who left sub-Saharan Africa about 70k years ago. We may best think of the relationship between these three groups not as a single highway, but as a triangle with two sides 70k long and one side of 40k. But to accurately add more groups to our journey, (as we shall do on Thursday), we would have to keep adding dimensions, and we are aiming here for simplicity, not n-dimensional hypercubes.

Humanity's path out of Africa
Humanity’s path out of Africa

The history of humanity’s long sojourn across the globe has resulted in, more or less, three main super-clades, or races: Sub-Saharan Africans, Caucasians, and Asians. The words we use for these are not perfect (“Caucasian” is particularly imprecise,) but do the job well enough.

Genetic distance map of 18 human groups, by Saitou Naruya

The Asian super-clade has three main branches: Melanesians (and Aborigines,) who traveled south into the Pacific; the Native Americans, who settled North and South America some 13-40,000 years ago; and of course the East Asians, like the Chinese, Japanese, and Polynesians.

(Amusingly, Indians, though they clearly live in Asia, are part of the Caucasian clade because they are more closely related to Middle Easterners and Europeans than Chinese people. As a result, Indians were–for a while—recorded as “white” on US censuses, though today they are recorded as “Asian.”)

People are fond of saying that the SS African race contains the greatest genetic diversity (as well it might, due to the inclusion of groups like the Pygmies and Bushmen, who may have split off from other human groups over 100,000 years ago,) but the Asian race has the greatest pre-Columbian geographic/environmental range, stretching from Australia and Polynesia to Siberia and Greenland, from Mongolia to Patagonia.

Trying to offer a single, coherent description of the physical appearances of such a diverse range of peoples is nearly impossible. They range in skin tone from almost white to as black as most of Africa; in stature from slight, Pygmy-like Negritos to the formidable Comanches (who in the 1800s were among the world’s tallest measured people;) and in average reported IQs from >105 to >65. (Okay, IQ isn’t appearance.)

We will be able to speak much more meaningfully about appearances when we address each of the sub-races.

Here are the relevant portions from Haak et al’s lovely dataset:

nativeamerican eskimoonge eastasian

On the left, we have the Native American DNA, from the depths of the Amazonian rainforest to the tribes of upstate New York. The olive green section are the Inuit/Eskimo and related Russian groups. The Inuit (who appear to have wiped out the earlier Dorset people,) share a great deal of DNA with other Siberians, eg the Yakuts (a Turkic people) and the Nganasan, (who speak a highly divergent language of the Samoyedic branch of the Uralic family, which also includes the Finnish, Hungarian, and Sami languages–language is a very bad guide to genetics.)

The pale peach are the Onge, who live in India’s Andaman Islands; purple the people of Papua New Guinea and Australia.

The very yellow part is all of the groups normally thought of as “East Asian,” like Japanese, Chinese, and Thai. Yellow is most dominant in the aboriginal people of Taiwan (who were there before the Chinese started migrating there in the past few hundred years,) and are the ancestors of the (not pictured) Polynesian peoples of Hawaii, Easter Island, and New Zealand. (I think they picked up some Melanesian DNA on the way.)

And on the right we have the various peoples of Siberia and central Asia.

I think it an open question whether the Melanesians and Aborigines ought to be properly classed with the other Asians, or awarded their own clade.

I totally stole this from Razib Khan, didn't I?
I stole this from Razib Khan, didn’t I?

According to Masatoshi Nei, a biology professor at Pennsylvania State University,[131]  the ancestors of today’s Asians and Caucasians split into two separate groups around 41,000 years ago, (give or take 15,000 years,) and their ancestors split from the ancestors of modern Africans–the “Out of Africa Event”–around 114,000 years ago, (give or take 34,000 years.)

 

The Daily Mail reports:

BERLIN (AP) — The human populations now predominant in Eurasia and East Asia probably split between 36,200 and 45,000 years ago, according to a study released Thursday.

Researchers used new techniques to analyze genetic samples from the shin bone of a young man who died at least 36,200 years ago near Kostenki-Borshchevo in what is now western Russia. The study, published in the journal Science, concludes that Kostenki man shared genetic sequences with contemporary Europeans, but not East Asians.

A separate study published last month in the journal Nature determined that a 45,000-year old sample found in Siberia contained sequences ancestral to both modern East Asians and Europeans.

Meanwhile:

In a genetic study in 2011, researchers found evidence, in DNA samples taken from strands of Aboriginal people’s hair, that the ancestors of the Aboriginal population split off from the ancestors of the European and Asian populations between 65,000 and 75,000 years ago—roughly 24,000 years before the European and Asian populations split off from each other. These Aboriginal ancestors migrated into South Asia and then into Australia…

A different study found:

The first complete sequences of the Y chromosomes of Aboriginal Australian men have revealed a deep indigenous genetic history tracing all the way back to the initial settlement of the continent 50 thousand years ago, according to a study published in the journal Current Biology today.

The Native Americans much more conveniently split off around 25,000 years ago.

Or in other words:

So on the one hand, race is biological and real, and on the other, it’s a social construct. Australian Aborigines are more closely related to other Asians than to, say, Europeans or Africans, but the Chinese are more closely related to Europeans than to Aborigines.

nature-siberian-neanderthals-17.02.16-v2One reason why Australians and other Melanesians appear so divergent from other Asian populations maybe their Denisovan (or other human) DNA. Most (if not all) human groups appear to have picked up DNA from some other, non-Homo Sapiens source. Europeans, East Asians, and Native Americans all have a small percent of Neanderthal DNA. Africans, IIRC, have a small % of some local African homin. And Melanesians/Australians have a small % of Denisovan DNA (Denisovans were a less-well-known cousin of the Neanderthals.)

Creationism, Evolutionism, and Categories

I’ve been thinking about the progression of ideas about natural categories, such as “men” and “women,” “cows” and “mules,” “English” and “Polynesian.” Not exactly our high philosophical progression, but a somewhat commoner one.

It seems that 100 years or so ago, most people would have explained the differences between things with a simple, “Because God wanted them to be that way.” And if God wants it that way, then the way they are is good and you should leave them alone.

I have heard my [sibling] wax practically poetic about the way God made mules and horses for farm work, and why you should not yoke together an ox and a donkey. (One of the interesting parts of meeting my siblings for the first time as an adult was realizing that dorkiness is genetic.)

The evolutionary perspective is that evolution created things (or, as we like to call it around here, GNON, the God of Nature and Nature’s God.) Gnon and God are functionally rather similar, for Gnon also made things in natural categories, and while we may refrain from deeming them “good” in quite the same way as religious people, we certainly believe that each group’s features serve purposes that have helped members of that group survive where others did not.

The conservative creationist denies the role of evolution, but he does not deny that categories exist. He merely disputes their method of creation. To quote Answers in Genesis:

So, a good rule of thumb is that if two things can breed together, then they are of the same created kind. …

As an example, dogs can easily breed with one another, whether wolves, dingoes, coyotes, or domestic dogs. When dogs breed together, you get dogs; so there is a dog kind. It works the same with chickens. There are several breeds of chickens, but chickens breed with each other and you still get chickens. So, there is a chicken kind. The concept is fairly easy to understand.

But in today’s culture, where evolution and millions of years are taught as fact, many have been led to believe that animals and plants (that are classed as a specific “species”) have been like this for tens of thousands of years and perhaps millions of years. So, when they see things like lions or zebras, they think they have been like this for an extremely long time.

From a biblical perspective, though, land animals like wolves, zebras, sheep, lions, and so on have at least two ancestors that lived on Noah’s Ark, only about 4,300 years ago. These animals have undergone many changes since that time. But dogs are still part of the dog kind, cats are still part of the cat kind, and so on. God placed variety within the original kinds, and other variation has occurred since the Fall due to genetic alterations.

For all that people accuse the Answers in Genesis folks of being crazy, and for all that they are trying awfully hard to re-invent the wheel, this is an unobjectionable approach to species and hybridization.

By contrast, the liberal creationist, since she cannot fall back on God in his rejection of Gnon, asserts that the categories themselves do not exist. “Race is a social construct. Gender is a social construct.” etc. Dr. Zuleyka Zevallos, who is definitely not a crazy Creationist with no respect for science, writes:

When people talk about the differences between men and women they are often drawing on sex – on rigid ideas of biology – rather than gender, which is an understanding of how society shapes our understanding of those biological categories.

Gender is more fluid – it may or may not depend upon biological traits. [bold mine.] More specifically, it is a concept that describes how societies determine and manage sex categories; the cultural meanings attached to men and women’s roles; and how individuals understand their identities including, but not limited to, being a man, woman, transgender, intersex, gender queer and other gender positions. …

The sociology of gender examines how society influences our understandings and perception  of differences between masculinity (what society deems appropriate behaviour for a “man”) and femininity (what society deems appropriate behaviour for a “woman”). We examine how this, in turn, influences identity and social practices. We pay special focus on the power relationships that follow from the established gender order in a given society, as well as how this changes over time.

And the New York Times writes:

Race is not biological. It is a social construct. There is no gene or cluster of genes common to all blacks or all whites. Were race “real” in the genetic sense, racial classifications for individuals would remain constant across boundaries. Yet, a person who could be categorized as black in the United States might be considered white in Brazil or colored in South Africa.

Answers in Genesis understands genetics better than the New York times or people with doctorates from actual universities. That is pretty damn pathetic.

crayon map of racial distribution. Not guaranteed correct
crayon map of racial distribution. Not guaranteed correct

Of course, some of our ideas about what “men” and “women”  or “blacks” and “whites” are like are cultural (especially any that involve technology, since technology has changed radically over the past 100 years.) As an amateur anthropologist, I am quite aware that different cultures have different ideas on these subjects. This does not negate the fact that “maleness” and “femaleness” are basically biologically-driven. Female interest in babies and male interest in violence has its roots in biology, not culture. Genetics have a huge effect on personality. Likewise, races are absolutely real, biological categories, which no doctor attempting an organ transplant can afford to ignore.

The idea that races don’t exist in some kind of genetic way is absurd. Let’s just take the EDAR gene:

Ectodysplasin A receptor (EDAR) is a protein that in humans is encoded by the EDAR gene. EDAR is a cell surface receptor for ectodysplasin A which plays an important role in the development of ectodermal tissues such as the skin.[3][4][5] …

A derived G-allele point mutation (SNP) with pleiotropic effects in EDAR, 370A or rs3827760, found in most modern East Asians and Native Americans but not common in African or European populations, is thought to be one of the key genes responsible for a number of differences between these populations, including the thicker hair, more numerous sweat glands, smaller breasts, and dentition characteristic of East Asians.[7]… The 370A mutation arose in humans approximately 30,000 years ago, and now is found in 93% of Han Chinese and in the majority of people in nearby Asian populations. The derived G-allele is a mutation of the ancestral A-allele, the version found in most modern non-East Asian and non-Native American populations.

Most East Asians and Native Americans (that is, the greater Asian Race,) have the G-allele of EDAR. Most non-Asians have the A-allele.

If you don’t have some form of causality to explain how the world’s variation came to exist, I guess you fall back on “it’s totally random and meaningless.”

Anthropology Friday: Gypsies

Vincent Van Gogh, The Caravans
Vincent Van Gogh, The Caravans

It is easy to romanticize the Gypsies–quaint caravans, jaunty music, and the nomadic lifestyle of the open road all lend themselves to pleasant fantasies. The reality of Gypsy life is much sadder. They are plagued by poverty, illiteracy, violence, the diseases of high consanguinity, and the meddling of outsiders, some better intentioned than others.

I’m going to start off with something which, if true, is rather poetic.

The Gypsies refer to themselves as Rom (or Romani.) I prefer “Gypsy” because I am an American who speaks English and “Gypsy” is the most accepted, well-known ethnonym in American English, but I am also familiar with Rom.

Anyway, there are a couple of other nomadic groups which appear to be related to the Rom, called the Lom and Dom (their langauges, respectively, are Romani, Domari, and Lomavren.) Genetically, these three groups may be the results of different waves of migration from India, where they may have originated from the Domba (or Dom) people.

All four groups speak Indo-European languages. According to Wikipedia:

Its presumed root, ḍom, which is connected with drumming, is linked to damara and damaru, Sanskrit terms for “drum” and the Sanskrit verbal root डम् ḍam- ‘to sound (as a drum)’, perhaps a loan from Dravidian, e.g. Kannadaḍamāra ‘a pair of kettle-drums’, and Teluguṭamaṭama ‘a drum, tomtom‘.[2]

The Gypsy flag features, appropriately, a wheel
The Gypsy flag features, appropriately, a wheel

Given the Gypsies’ reputation for musical ability, there is something lovely and poetic about having a name that literally means “Drum.”

Unfortunately, the rest of the picture is not so cheerful.

Isabel Fonseca recounts in Bury me Standing: The Gypsies and their Journey:

The new socialist government in postwar Poland aspired to build a nationally and ethnically homogenous state. Although the Gypsies accounted for about .005 percent of the population, “the Gypsy problem” was labeled an “important sate task,” and an Office of Gypsy Affairs was established under the jurisdiction of the Ministry of Internal Affairs–that is, the police. It was in operation until 1989.

In 1952 a broad program to enforce the settlement of Gypsies also came into effect: it was known a the Great Halt … The plan belonged to the feverish fashion for “productivization” which, with its well-intentioned welfare provisions, in fact imposed a new culture of dependency on the Gypsies, who had always opposed it. Similar legislation would be adopted in Czechoslovakia (1958), in Bulgaria (1958), and in Romania (1962), as the vogue for forced assimilation gathered momentum. … by the late 1960s settlement was the goal everywhere. In England and Wales … the 1968 Caravan Sites Act aimed to settle Gypsies (partially by a technique of population control known as “designation” in which whole large areas of the country were declared off-limits to Travelers). …

But no one has ever thought to ask the Gypsies themselves. And accordingly all attempts at assimilation have failed. …

In a revised edition of his great book The Gypsies in Poland, published in 1984, Ficowski reviews the results of the Big Halt campaign. “Gypsies no longer lead a nomadic life, and the number of illiterates has considerably fallen.” But even these gains were limited because Gypsy girls marry at the age of twelve or thirteen, and because “in the very few cases where individuals are properly educated, they usually tend to leave the Gypsy community.” The results were disastrous: “Opposition to the traveling of the Gypsy craftsmen, who had taken their tinsmithing or blacksmithing into the uttermost corner of the country, began gradually to bring about the disappearance of … most of the traditional Gypsy skills.” And finally, “after the loss of opportunities to practice traditional professions, [for many Gypsies] the main source of livelihood became preying on the rest of society.” Now there really was something to be nostalgic about. Wisdom comes too late. The owl of Minerva flies at dusk.

That a crude demographic experiment ended in rootlessness and squalor is neither surprising nor disputed… “

Cabrini Green, circa 1960
Cabrini Green, circa 1960

Of course, Gypsy life was not so great before settlement, either. Concentrations of poverty in the middle of cities may be much easier to measure and deplore than half-invisible migrant people on the margins of society, but no one appreciates being rounded up and forced into ghettos.

I am reminded here of all of the similar American attempts, from Pruit Igoe to Cabrini Green. Perhaps people had good intentions upon building these places. New, clean, cheap housing. A community of people like oneself, in the heart of a thriving city.

And yet they’ve all failed pretty miserably.

On the other hand, the Guardian reports on  violence (particularly domestic) in Gypsy communities in Britain:

..a study in Wrexham, cited in a paper by the Equality and Human Rights Commission, 2007, found that 61% of married English Gypsy women and 81% of Irish Travellers had experienced domestic abuse.

The Irish Travellers are ethnically Irish, not Gypsy, but lead similarly nomadic lives.

“I left him and went back to my mammy but he kept finding me, taking me home and getting me pregnant,” Kathleen says. She now feels safe because she has male family members living on the same site. “With my brother close by, he wouldn’t dare come here.” …

But domestic violence is just one of the issues tackled by O’Roarke during her visits. The welfare needs, particularly those of the women and girls, of this community are vast. The women are three times more likely to miscarry or have a still-born child compared to the rest of the population, mainly, it is thought, as a result of reluctance to undergo routine gynaecological care, and infections linked to poor sanitation and lack of clean water. The rate of suicides among Traveller women is significantly higher than in the general population, and life expectancy is low for women and men, with one third of Travellers dying before the age of 59. And as many Traveller girls are taken out of education prior to secondary school to prevent them mixing with boys from other cultures, illiteracy rates are high. …

Things seem set to get worse for Traveller women. Only 19 days after the general election last year, £50m that had been allocated to building new sites across London was scrapped from the budget. O’Roarke is expecting to be the only Traveller liaison worker in the capital before long – her funding comes from the Irish government.

“Most of the women can’t read or write. Who is supposed to help them if they get rid of the bit of support they have now?” asks O’Roarke. “We will be seeing Traveller women and their children on the streets because of these cuts. If they get a letter saying they are in danger of eviction but they can’t read it, what are they supposed to do?”

August Von Pettenkofen, Gipsy Children
August Von Pettenkofen, Gipsy Children

Welfare state logic is painful. Obviously Britain is a modern, first-world country with a free education system in which any child, male or female, can learn to read (unless they are severely low-IQ.) If Gypsies and Travellers want to preserve their cultures with some modicum of dignity, then they must read, because literacy is necessary in the modern economy. Forced assimilation or not, no one really needs traditional peripatetic tin and blacksmiths anymore. Industrialization has eliminated such jobs.

Kathleen, after spending time in a refuge after finally managing to escape her husband, was initially allocated a house, as opposed to a plot on a [trailer] site. Almost immediately her children became depressed. “It’s like putting a horse in a box. He would buck to get out,” says Kathleen. “We can’t live in houses; we need freedom and fresh air. I was on anti-depressives. The children couldn’t go out because the neighbours would complain about the noise.”

Now this I am more sympathetic to. While I dislike traveling, largely because my kids always get carsick, I understand that plenty of people actually like being nomadic. Indeed, I wouldn’t be surprised if some people were genetically inclined to be outside, to move, to be constantly on the road, while others were genetically inclined to settle down in one place. To try to force either person into a lifestyle contrary to their own nature would be cruel.

Disease, lifestyle, and consanguinity in 58 American Gypsies:

Medical data on 58 Gypsies in the area of Boston, Massachusetts, were analysed together with a pedigree linking 39 of them in a large extended kindred. Hypertension was found in 73%, diabetes in 46%, hypertriglyceridaemia in 80%, hypercholesterolaemia in 67%, occlusive vascular disease in 39%, and chronic renal insufficiency in 20%. 86% smoked cigarettes and 84% were obese. Thirteen of twenty-one marriages were consanguineous, yielding an inbreeding coefficient of 0.017. The analysis suggests that both heredity and environment influence the striking pattern of vascular disease in American Gypsies.

Genetic studies of the Roma (Gypsies) A review:

Although far from systematic, the published information indicates that medical genetics has an important role to play in improving the health of this underprivileged and forgotten people of Europe. Reported carrier rates for some Mendelian disorders are in the range of 5 -15%, sufficient to justify newborn screening and early treatment, or community-based education and carrier testing programs for disorders where no therapy is currently available. …

12881_2001_article_6_fig2_htmlReported gene frequencies are high for both private and “imported” mutations, and often exceed by an order of magnitude those for global populations. For example, galactokinase deficiency whose worldwide frequency is 1:150,000 to 1:1,000,000 [56,57] affects 1 in 5,000 Romani children [44]; autosomal dominant polycystic kidney disease (ADPKD) has a global prevalence of 1:1000 individuals worldwide [58] and 1:40 among the Roma in some parts of Hungary [17]; primary congenital glaucoma ranges between 1:5,000 and 1:22,000 worldwide [59,60] and about 1:400 among the Roma in Central Slovakia [61,62].

Carrier rates for a number of disorders have been estimated to be in the 5 to 20% range (Table 3). …

Historical demographic data are limited, however tax registries and census data give an approximate idea of population size and rate of demographic growth through the centuries (Table 4). A small size of the original population is suggested by the fact that although most of the migrants arriving in Europe in the 11th-12th century remained within the limits of the Ottoman Empire [1,75], the overall number of Roma in its Balkan provinces in the 15th century was estimated at only 17,000. …

12881_2001_article_6_fig4_htmlDuring its subsequent history in Europe, this founder population split into numerous socially divided and geographically dispersed endogamous groups, with historical records from different parts of the continent consistently describing the travelling Gypsies as “a group of 30 to 100 people led by an elder” [1,2]. These splits, a possible compound product of the ancestral tradition of the jatis of India, and the new social pressures in Europe (e.g. Gypsy slavery in Romania [76] and repressive legislation banning Gypsies from most western European countries [1,2]), can be regarded as secondary bottlenecks, reducing further the number of unrelated founders in each group. The historical formation of the present-day 8 million Romani population of Europe is therefore the product of the complex initial migrations of numerous small groups, superimposed on which are two large waves of recent migrations from the Balkans into Western Europe, in the 19th – early 20th century, after the abolition of slavery in Rumania [1,2,76] and over the last decade, after the political changes in Eastern Europe [7,8]. …

Individual groups can be classified into major metagroups [1,2,75]: the Roma of East European extraction; the Sinti in Germany and Manouches in France and Catalonia; the Kaló in Spain, Ciganos in Portugal and Gitans of southern France; and the Romanichals of Britain [1]. The greatest diversity is found in the Balkans, where numerous groups with well defined social boundaries exist. The 700-800,000 Roma in Bulgaria belong to three metagroups, comprising a large number of smaller groups [75].

Of course, if you want the full details on consanguinity in Gypsies, you have to read HBDChick:

the actual cousin marriage rates vary though from (as you’ll see below) ca. 10-30% first cousin only marriages amongst gypsies in slovakia to 29% first+second cousin marriages amongst gypsies in spain [pdf] to 36% first+second cousin marriages amongst gypsies in wales [pdf]. these rates are comparable to those found in places like turkey (esp. eastern turkey) or north africa…or southern india.

I’m not quoting the whole thing for you; you’ll just have to go read the whole thing yourself.

Health Status of Gypsies and Travellers in England:

The 1987 national study of Travellers’ health status in Ireland11 reported a high death rate for all causes and lower life expectancy for Irish Travellers: women 11.9 years and men 9.9 years lower than the non‐Traveller population. Our pilot study of 87 Gypsies and Travellers matched for age and sex with indigenous working class residents in a socially deprived area of Sheffield,12 reported statistically and clinically significant differences between Gypsies and Travellers and their non‐Gypsy comparators in some aspects of health status, and significant associations with smoking and with frequency of travelling. The report of the Confidential Enquiries into Maternal Deaths in the UK, 1997–1999, found that Gypsies and Travellers have “possibly the highest maternal death rate among all ethnic groups”.13

picture-1And as Dr. James Thompson notes, Gypsies do not do well on IQ tests, with many groups scoring in the 60-85 range. (White Americans average 100.)

This is all kind of depressing, but I have a thought: if Gypsies want to preserve their culture and improve their lives, perhaps the disease burden may be lessened and IQs raised by encouraging young Gypsy men and women to find partners in other Gypsy groups from other countries instead of from within their own kin groups.

According to Wikipedia:

Further evidence for the South Asian origin of the Romanies came in the late 1990s. Researchers doing DNA analysis discovered that Romani populations carried large frequencies of particular Y chromosomes (inherited paternally) and mitochondrial DNA (inherited maternally) that otherwise exist only in populations from South Asia.

47.3% of Romani men carry Y chromosomes of haplogroup H-M82 which is rare outside South Asia.[18] Mitochondrial haplogroup M, most common in Indian subjects and rare outside Southern Asia, accounts for nearly 30% of Romani people.[18] A more detailed study of Polish Roma shows this to be of the M5 lineage, which is specific to India.[19] Moreover, a form of the inherited disorder congenital myasthenia is found in Romani subjects. This form of the disorder, caused by the 1267delG mutation, is otherwise known only in subjects of Indian ancestry. This is considered to be the best evidence of the Indian ancestry of the Romanis.[20]

I must stop here and note that I have painted a largely depressing picture. It is not the picture I want to paint. I would like to paint a picture of hope and triumph. Certainly there are many talented, hard-working, kind, decent, and wonderful Gypsies. I hope the best for them, and a brighter future for their children.

Wise Tim, Crime, and HBD: Part 2, the HBD-view expanded

Continuing with our discussion of Leuconoe’s question:

What is your opinion of the “racial invariance hypothesis” which says that poor whites have about the same crime rate as poor blacks and that if you control for socioeconomic status all the differences between the races in crime go away?

This thesis is mainly backed by these studies: Poverty, not race, tied to high crime rates in urban communities, Homicide in Black and White (pdf.)

Since poor whites have a generally higher IQ as equally poor blacks this would also contradict the idea that lower IQ leads to more crime. …

Also this piece by a radical leftist: Nazis Can’t Do Math: Reflections on Racism, Crime and the Illiteracy of Right-Wing Statistical Analysis.

First, let’s be clear about what HBD says (and doesn’t say) about crime, race, and poverty (and while we’re at it, IQ):

  1. Genes influence traits like IQ and criminality.

As JayMan is fond of saying, “All human behavioral traits are heritable.” Okay, but what does this mean? Are we slaves to our genetics? Is there a a murder gene that guarantees that you will go out and stab someone to death? Since JayMan has already written a great explanation, I will quote him and urge you to read the rest:

The First Law emerges from studies of twins, studies of adoptees, and (now) sibling genetic similarity studies. In short, when you look at people’s behavior, virtually without exception … you find some effect of the genes on these traits….

How could this be, you may ask? How could such complex and highly specific things be encoded in the DNA and express themselves despite decades of upbringing and childhood experiences? For one, heritability is only probabilistic, not absolute. Few traits are 100% heritable. …

But, it’s important to understand the meaning of the term heritability. Heritability is the degree of variation in a studied population that can be attributed to genetic variation in that population. The cause is the variance in question is always due to some genetic difference, but it doesn’t tell you how direct such genetic influence is. …

So, how iron-clad is the First Law? Clearly, not all traits are heritable, right? Right. However, there are only a distinct set of exceptions. Traits that are dependent on content aren’t heritable at all. These include what language you speak, in which particular church you worship, what specific political party you identify. However, the degree and manner to which one interacts with these things are very heritable: how proficient you are with language, how church-going you are, how liberal or conservative.

Note that these are not 100% heritable. There is no “guaranteed to stab people” gene, but there are genes that will make you more likely to want to stab people. Environment, “free will,” and random chance also influence how personality traits manifest in individuals.

Edit: It occurs to me that I should actually talk about some of these genes.

An MAOA variant, nicknamed “the warrior gene,” is the most famous of these. Wikipedia states:

A version of the monoamine oxidase-A gene has been popularly referred to as the warrior gene.[30] Several different versions of the gene are found in different individuals, although a functional gene is present in most humans (with the exception of a few individuals with Brunner syndrome).[31] In the variant, the allele associated with behavioural traits is shorter (30 bases) and may produce less MAO-A enzyme.[32] This gene variation is in a regulatory promoter region about 1000 bases from the start of the region that encodes the MAO-A enzyme.

Studies have found differences in the frequency distribution of variants of the MAOA gene between ethnic groups:[32][33] of the participants, 59% of Black men, 54% of Chinese men, 56% of Maori men, and 34% of Caucasian men carried the 3R allele, while 5.5% of Black men, 0.1% of Caucasian men, and 0.00067% of Asian men carried the 2R allele.[23][32][33][34][35][36][37][38][39][40]

In individuals with the low activity MAOA gene, when faced with social exclusion or ostracism showed higher levels of aggression than individuals with the high activity MAOA gene.[41]

Doubtless there are other genes I’m not aware of.

2.  The frequency of different genes varies between genetically-related groups.

The obvious genes here are ones that code for environmental responses, like lactase persistence in groups that have historically practiced dairy farming and dark skin in areas with intense sunlight.

Everyone on earth shares more genes with the people closely related to them than people less-closely related. For example, the Amish are more genetically similar to other Amish than non-Amish. Pygmies are more closely related to other pygmies than non-pygmies. This is why people look like their parents.

There are a lot of people who claim that “race is a social construct.” From a genetic standpoint, this is simply untrue (look at the top of the blog for an example of how geneticists can distinguish between different genetic groups.)

3. The HBD-theory is that the genes for personality/behavioral traits also vary by genetically-related groups, due to historical environmental (including cultural!) pressures.

For example, Polynesians may have been selected for navigational ability, because good navigators populated Polynesia and bad navigators died at sea. Chinese culture may have selected for people willing to work hard and get along even when they don’t really feel like it; and the Inuit may have been selected for the ability to stand really long, dark winters.

Relevant to our discussion, crime rates vary a lot by region:

and society:

We’ve discussed warfare in pre-state societies over quite a few posts lately, so I’m going to summarize quickly: anthropological, historical, and archaeological records all document extremely high rates of violence in non-state societies. Anthropologist Napoleon Chagnon actually kept track of both homicides and births among the Yanomamo, and found that Yanomamo men who had killed more people had more children than Yanomamo men who had killed fewer people, providing a direct mechanism for genetic selection for traits related to homicide and other violence.

Many HBD bloggers, such as Peter Frost and HBD Chick, have discussed the ways in which states have discouraged crime, including (especially) executing criminals and thus preventing them from having children. The observed result:

homicide_in_europe_1200_2000

 

That all said, there are things that no serious HBD-er claims:

A. That all people or sub-groups within a “race” are identical. As Peter Frost wrote, “No, blacks aren’t all alike. Who said they are?” There are smart black people and dumb black people. Hard-working whites and lazy whites. Extroverted Asians and Introverted Asians. Some white groups (like Russians, apparently,) have significantly higher crime rates than other white groups. Even within the US, there are differences between different groups of whites, with significant ethnic divisions between classes and regions.

B. That environmental effects don’t exist or that humans do not respond to incentives. Obviously if it is cold outside I will wear a coat; if a law is passed that jay walkers will be executed, I will immediately stop jaywalking.

C. Observed differences are set in stone. The world is always changing. Where selection pressures change, so do populations.

 

So to get back to Leuconoe’s first query, I would not be surprised if controlling for socioeconomic status made all (or most) racial differences in criminality disappear. In fact, this is basically what I would expect, because poverty, criminality, and low-IQ are correlated, so controlling for one will tend to control for all of them.

But why on earth would you do this? If we control for bad decisions, most differences in intelligence disappear. If you control for enough differences, differences disappear. But as JayMan says, you can’t just control for a groups entire history; likewise, you can’t just control for all their traits.

Moreover, this still doesn’t get at why different groups have different rates of criminality or poverty in the first place, nor whether A causes B, B causes A, or C causes A and B. And even if you could prove that poverty causes crime, you still haven’t answered why there’s so much more poverty in black communities than in white (or Asian) ones.

What do we know about race and crime in America?

I have written a few posts on the subject, like When Crime is a Euphemism for Lynching; Bullying Pt 2: Race, Crime, and the Police; South Africa, Democracy, and the Dangers of Demographics (okay that one is on South Africa, not America); Rupert Murdoch is a Lying Liar; Sorry, Les Mis: Criminals Gonna Criminal.

Given that I’ve written nearly 500 posts, this is clearly not my main focus. I therefore recommend everything by La Griffe du Lion, including Crime in the Hood; Crime and the Hispanic Effect; Politics, Imprisonment, and Race; Aggressiveness, Criminality, and Sex Drive by Race, Gendder, and Ethnicity; The Color of Death Row; and Analysis of Hate Crime. And if that is not enough for you, here is the entire updated Color of Crime, from whoever publishes it. Here are a few of its major findings:

  • The evidence suggests that if there is police racial bias in arrests it is negligible. Victim and witness surveys show that police arrest violent criminals in close proportion to the rates at which criminals of different races commit violent crimes.
  • There are dramatic race differences in crime rates. Asians have the lowest rates, followed by whites, and then Hispanics. Blacks have notably high crime rates. This pattern holds true for virtually all crime categories and for virtually all age groups.
  • In 2013, of the approximately 660,000 crimes of interracial violence that involved blacks and whites, blacks were the perpetrators 85 percent of the time. This meant a black person was 27 times more likely to attack a white person than vice versa. A Hispanic was eight times more likely to attack a white person than vice versa.
  • If New York City were all white, the murder rate would drop by 91 percent, the robbery rate by 81 percent, and the shootings rate by 97 percent.
  • Both violent and non-violent crime has been declining in the United States since a high in 1993. 2015 saw a disturbing rise in murder in major American cities that some observers associated with “depolicing” in response to intense media and public scrutiny of police activity.

So much for controlling for income. It looks like equally poor whites and blacks still have massively different homicide rates. (Of course, I should note that the US welfare system attempts to put a minimum floor below which people don’t fall. Without intervention, equally poor whites and blacks might be more similar.)

West Hunter noted about the effects of lotteries:

Lotteries can be useful natural experiments; we can use them to test the accuracy of standard sociological theories, in which rich people buy their kids extra smarts, bigger brains, better health, etc.

David Cesarini, who I met at that Chicago meeting, has looked at the effect of winning the lottery in Sweden. He found that the “effects of parental wealth on infant health, drug consumption, scholastic performance and cognitive and non-cognitive skills can be bounded to a tight interval around zero.”

As I once mentioned, there was an important land lottery in Georgia in 1832. The winners received an 160-acre farm. But by 1880, their descendants were no more literate, their occupational status no higher. The families in the top 2/3rds of income managed to hang on to some of their windfall, but lower-income families did not.

West Hunter does note that there is probably a level below which material deprivation really will harm (or kill) you, and that a random windfall in such a situation will do you good, but virtually no one in the modern West lives in famine or near-famine conditions.

Open Thread: International Solidarity

polandballworldOne of the things I find interesting about the online community I find myself more-or-less in (that is, you guys who comment here, the folks who link to me and their commentators, folks on Twitter, etc.,) is the sense of, shall we say, international solidarity.

This is all rather novel for me.

picture-2Those of us in America have been expressing concern about events unfolding in Britain and even Sweden. I have received (for the first time in my life!) kind words about America from from French people. And I like to think that with Trump’s election, the Russian people have been reassured that not all Americans want to go to war with them. (Just Hillary Clinton.)

t3_5g2114One of my long-standing issues with the left is the sheer negativity; they don’t call it a circular firing squad for nothing. “Call-out culture” is very toxic, cultish, and poisonous. (How exactly SJW ideology functions like a cult is a long post for another day, but it does.) So here we have, on what, the right? an emerging belief that one’s culture is unique and worth having and respecting the fact that other people love their own cultures and want to preserve them, too, without going down that path where Americans end up attacking confused Japanese women for wearing kimonos at an art exhibit about kimonos.

I don’t know enough about foreign politics to comment much at all on it. I don’t know who would be the best leader for this or that country. But that doesn’t stop me from appreciating other countries and wishing the best for their people.

Hrm, on to the (hopefully) interesting links section of this post:

Before we get to chew on the Bell Beaker behemoth, probably early next year if not sooner, here’s an appetizer on a similar topic…

Genome-wide analyses for personality traits identify six genomic loci and show correlations with psychiatric disorders:

The first genetic dimension separated personality traits and psychiatric disorders, except that neuroticism and openness to experience were clustered with the disorders. High genetic correlations were found between extraversion and attention-deficit–hyperactivity disorder (ADHD) and between openness and schizophrenia and bipolar disorder.

The Genetic History of Horses:

The oldest successfully extracted DNA came from the skeleton of a wild horse that lived in the Yukon between 560,000 – 780,000 years ago. Such samples are especially important because there are very few wild horses left alive, and modern horse breeding practices have obscured the genomic signature of early domestication qualities like geography. Thanks to data from ancient DNA, geneticists have learned that a previously unknown group of now-extinct wild horses were also ancestors to modern horses.

Remarkably, the majority of Y-chromosomes carried by modern domestic horses can be traced back to just a few stallions. This could be because only a few males were originally used in domestication, but it could also result from carefully controlled modern breeding practices where a single male sires a huge number of offspring. The ultimate cause of this very low Y-linked diversity is still debated, but strict selective breeding has almost certainly contributed. In contrast, a much larger number of females than males contributed ancestry to domestic horses. According to Librado and colleagues, it seems that wild mares were continuously introduced into human-controlled herds throughout the process of domestication.

Comment of the week goes to N8 N3K:

“How do you get states to start forming so that criminals can be punished and revenge spirals halted?”

Criminals compete with each other. Everything some other criminal steals is something you can’t steal yourself. And the theft discourages production in general. So it might make sense for a gang of criminals to eradicate all others and to fund a state to protect their monopoly on violence. …
