Two Exciting Papers on African Genetics

I loved that movie

An interesting article on Clues to Africa’s Mysterious Past appeared recently in the NY Times:

It was only two years ago that researchers found the first ancient human genome in Africa: a skeleton in a cave in Ethiopia yielded DNA that turned out to be 4,500 years old.

On Thursday, an international team of scientists reported that they had recovered far older genes from bone fragments in Malawi dating back 8,100 years. The researchers also retrieved DNA from 15 other ancient people in eastern and southern Africa, and compared the genes to those of living Africans.

Let’s skip to the article, Reconstructing Prehistoric African Population Structure by Skoglund et al:

We assembled genome-wide data from 16 prehistoric Africans. We show that the anciently divergent lineage that comprises the primary ancestry of the southern African San had a wider distribution in the past, contributing approximately two-thirds of the ancestry of Malawi hunter-gatherers ∼8,100–2,500 years ago and approximately one-third of the ancestry of Tanzanian hunter-gatherers ∼1,400 years ago.

Paths of the great Bantu Migration

The San are also known as the Bushmen, a famous group of recent hunter-gatherers from southern Africa.

We document how the spread of farmers from western Africa involved complete replacement of local hunter-gatherers in some regions…

This is most likely the Great Bantu Migration, which I wrote about in Into Africa: the Great Bantu Migration.

…and we track the spread of herders by showing that the population of a ∼3,100-year-old pastoralist from Tanzania contributed ancestry to people from northeastern to southern Africa, including a ∼1,200-year-old southern African pastoralist…

Whereas the two individuals buried in ∼2,000 BP hunter-gatherer contexts in South Africa share ancestry with southern African Khoe-San populations in the PCA, 11 of the 12 ancient individuals who lived in eastern and south-central Africa between ∼8,100 and ∼400 BP form a gradient of relatedness to the eastern African Hadza on the one hand and southern African Khoe-San on the other (Figure 1A).

The Hadza are a hunter-gatherer group from Tanzania who are not obviously related to any other people. Their language has traditionally been classed alongside the languages of the KhoiSan/Bushmen people because they all contain clicks, but the languages otherwise have very little in common and Hadza appears to be a language isolate, like Basque.

The genetic cline correlates to geography, running along a north-south axis with ancient individuals from Ethiopia (∼4,500 BP), Kenya (∼400 BP), Tanzania (both ∼1,400 BP), and Malawi (∼8,100–2,500 BP), showing increasing affinity to southern Africans (both ancient individuals and present-day Khoe-San). The seven individuals from Malawi show no clear heterogeneity, indicating a long-standing and distinctive population in ancient Malawi that persisted for at least ∼5,000 years (the minimum span of our radiocarbon dates) but which no longer exists today. …

We find that ancestry closely related to the ancient southern Africans was present much farther north and east in the past than is apparent today. This ancient southern African ancestry comprises up to 91% of the ancestry of Khoe-San groups today (Table S5), and also 31% ± 3% of the ancestry of Tanzania_Zanzibar_1400BP, 60% ± 6% of the ancestry of Malawi_Fingira_6100BP, and 65% ± 3% of the ancestry of Malawi_Fingira_2500BP (Figure 2A). …

Both unsupervised clustering (Figure 1B) and formal ancestry estimation (Figure 2B) suggest that individuals from the Hadza group in Tanzania can be modeled as deriving all their ancestry from a lineage related deeply to ancient eastern Africans such as the Ethiopia_4500BP individual …

So what’s up with the Tanzanian expansion mentioned in the summary?

Western-Eurasian-related ancestry is pervasive in eastern Africa today … and the timing of this admixture has been estimated to be ∼3,000 BP on average… We found that the ∼3,100 BP individual… associated with a Savanna Pastoral Neolithic archeological tradition, could be modeled as having 38% ± 1% of her ancestry related to the nearly 10,000-year-old pre-pottery farmers of the Levant These results could be explained by migration into Africa from descendants of pre-pottery Levantine farmers or alternatively by a scenario in which both pre-pottery Levantine farmers and Tanzania_Luxmanda_3100BP descend from a common ancestral population that lived thousands of years earlier in Africa or the Near East. We fit the remaining approximately two-thirds of Tanzania_Luxmanda_3100BP as most closely related to the Ethiopia_4500BP…

…present-day Cushitic speakers such as the Somali cannot be fit simply as having Tanzania_Luxmanda_3100BP ancestry. The best fitting model for the Somali includes Tanzania_Luxmanda_3100BP ancestry, Dinka-related ancestry, and 16% ± 3% Iranian-Neolithic-related ancestry (p = 0.015). This suggests that ancestry related to the Iranian Neolithic appeared in eastern Africa after earlier gene flow related to Levant Neolithic populations, a scenario that is made more plausible by the genetic evidence of admixture of Iranian-Neolithic-related ancestry throughout the Levant by the time of the Bronze Age …and in ancient Egypt by the Iron Age …

There is then a discussion of possible models of ancient African population splits (were the Bushmen the first? How long have they been isolated?) I suspect the more ancient African DNA we uncover, the more complicated the tree will become, just as in Europe and Asia we’ve discovered Neanderthal and Denisovan admixture.

They also compared genomes to look for genetic adaptations and found evidence for selection for taste receptors and “response to radiation” in the Bushmen, which the authors note “could be due to exposure to sunlight associated with the life of the ‡Khomani and Ju|’hoan North people in the Kalahari Basin, which has become a refuge for hunter-gatherer populations in the last millenia due to encroachment by pastoralist and agriculturalist groups.”

(The Bushmen are lighter than Bantus, with a more golden or tan skin tone.)

They also found evidence of selection for short stature among the Pygmies (which isn’t really surprising to anyone, unless you thought they had acquired their heights by admixture with another very short group of people.)

Overall, this is a great paper and I encourage you to RTWT, especially the pictures/graphs.

Now, if that’s not enough African DNA for you, we also have Loci Associated with Skin Pigmentation Identified in African Populations, by Crawford et al:

Examining ethnically diverse African genomes, we identify variants in or near SLC24A5, MFSD12, DDB1, TMEM138, OCA2 and HERC2 that are significantly associated with skin pigmentation. Genetic evidence indicates that the light pigmentation variant at SLC24A5 was introduced into East Africa by gene flow from non-Africans. At all other loci, variants associated with dark pigmentation in Africans are identical by descent in southern Asian and Australo-Melanesian populations. Functional analyses indicate that MFSD12 encodes a lysosomal protein that affects melanogenesis in zebrafish and mice, and that mutations in melanocyte-specific regulatory regions near DDB1/TMEM138 correlate with expression of UV response genes under selection in Eurasians.

I’ve had an essay on the evolution of African skin tones sitting in my draft folder for ages because this research hadn’t been done. There’s plenty of research on European and Asian skin tones (skin appears to have significantly lightened around 10,000 years ago in Europeans,) but much less on Africans. Luckily for me, this paper fixes that.

Looks like SLC24A5 is related to that Levantine/Iranian back-migration into Africa documented in the first paper.

Anthropology Friday: Indian Warriors and their Weapons (3/4) the Sioux

Chief Sitting Bull, Lakota Sioux, ca 1831 – 1890

Welcome back to Anthropology Friday. Today we’ll be looking at the Sioux Indians, from Hofsinde Gray-Wolf’s series about Native American culture with selections from Indian Warriors and their Weapons. According to Wikipedia, there are about 170,000 Sioux alive today, primarily the Dakota, Lakota, and Nakota. (I’m going to hazard a guess that Da, La, and Na are prefixes that refer to directions or locations.)

Hofsinde Gray-Wolf begins the section on the Sioux with an entertaining (but too long to recount here) story about a Sioux scout who spots some Pawnee hunting on Sioux land. A band of Sioux warriors pursues and surprises the Pawnee, getting the upper hand on them. Wikipedia notes:

Author and historian Mark van de Logt wrote: “Although military historians tend to reserve the concept of “total war” for conflicts between modern industrial nations, the term nevertheless most closely approaches the state of affairs between the Pawnees and the Sioux and Cheyennes. Both sides directed their actions not solely against warrior-combatants but against the people as a whole. Noncombatants were legitimate targets. … It is within this context that the military service of the Pawnee Scouts must be viewed.”[16]

The battle of Massacre Canyon on August 5, 1873, was the last major battle between the Pawnee and the Sioux.[17]

Air burial of a Sioux chieftain

On Massacre Canyon:

The Massacre Canyon Battle took place on August 5, 1873, in Hitchcock County, Nebraska. It was one of the last battles between the Pawnee and the Sioux (or Lakota) and the last large-scale battle between Native American tribes in the area of the present-day United States of America.[2] The battle occurred when a combined Oglala/Brulé Sioux war party of over 1000 warriors attacked a party of Pawnee on their summer buffalo hunt. More than 60 Pawnees died, mostly women and children. Along with the assault on Pawnee chief Blue Coat’s village in 1843, this battle range among “the bloodiest attacks by the Sioux” in Pawnee history.[3] …

John Williamson (23), was assigned as the Pawnee trail-agent at the Genoa Agency, the Pawnee reservation, and accompanied the Pawnee on their hunt. He wrote his recollections of the battle decades after the incident.[24]

“On the fourth day of August we reached the north bank of the Republican River and went into camp. At 9 o’clock that evening, three white men came into camp and reported to me that a large band of Sioux warriors were camped 25 miles [40 km] northwest, waiting for an opportunity to attack the Pawnees for several days, anticipating that we would move up the river where buffaloes were feeding. Previous to this, white men visited us and warned us to be on our guard against Sioux attacks, and I was a trifle skeptical as to the truth of the story told by our white visitors. But one of the men, a young man about my age at the time, appeared to be so sincere in his efforts to impress upon me that the warning should be heeded, that I took him to Sky Chief who was in command that day, for a conference. Sky Chief said the men were liars; that they wanted to scare the Pawnees away from the hunting grounds so that white men could kill buffaloes for hides. He told me I was squaw and a coward. I took exception to his remarks, and retorted: ‘I will go as far as you dare go. Don’t forget that.’

“The following morning August 5, we broke camp and started north, up the divide between the Republican and the Frenchman Rivers. Soon after leaving camp, Sky Chief rode up to me and extending his hand said, ‘Shake, brother.’ He recalled our little unpleasantness the night previous and said he did not believe there was cause for alarm, and was so impressed with the belief that he had not taken the precaution to throw out scouts in the direction the Sioux were reported to be. A few minutes later a buffalo scout signaled that buffaloes had been sighted in the distance, and Sky Chief rode off to engage in the hunt. I never saw him again. He had killed a buffalo and was skinning it when the advance guard of the Sioux shot and wounded him. The Chief attempted to reach his horse, but before he was able to mount, several of the enemy surrounded him. He died fighting. A Pawnee, who was skinning a buffalo a short distance away, but managed to escape, told me how Sky Chief died.” …

The whites rode up the canyon in the afternoon. “The first body we came upon was that of a woman”, remembered Platt.[32] Army doctor David Franklin Powell described the march up the battleground, “We advanced from the mouth of the ravine to its head and found fifty-nine dead Pawnees …”.[33] A number of the killed women lay naked. “Although the Pawnees made a stand and fought through the day, over a hundred were wounded, killed, or raped and mutilated”.[34]

(So much for “Primitive people were peaceful and never made war.”)

The last week of August, Williamson was back in Massacre Canyon. He covered the dead with dirt broken down from the banks.[43] …

This incident, in particular, caused the government nationwide to intensify “its efforts to keep the Indians confined to their reservation” in an endeavor to curtail intertribal warfare.[49] On local level, Major General George Crook “dispatched a small force” to protect the Pawnee Agency. The presence of troops did not stop the Sioux Raids.[50]

It would take half a century, before the Pawnee and the Sioux smoked the pipe of peace during the Massacre Canyon Pow Wow in 1925.[51]

Note that there were also wars between whites and Sioux, EG the Dakota War.

Scalp dance of the Minitarres

But back to Hofsinde Gray-Wolf:

“On their return to the Sioux encampment the men rode around the village. They had lost only warrior and only one other was wounded, so there was great jubilation. …

“In the evening a victory dance was held. The victory dance was also called a scalp dance because during it the warriors displayed the scalps they had taken. Afterwards the scalps were burned. … Those men who had earned coups in the battle had prepared their coup feathers before the dance. Two of the warriors wore and eagle feather standing upright behind their head. To the tip of the feather they had tied a tuft of horsehair, dyed brilliant red. Those coup feathers were of the highest order and showed that the wearers had, without any weapons in their hands, ridden in among the enemy. … they had dared to ride close enough to strike warriors with their bare hands. … One warrior hand a notch cut into the edge of his feather, and by this sign everyone knew that he had cut an enemy throat. …

“When he had won thirty coup feathers, a Sioux had earned the right to wear a full war bonnet.”

EvX: One of the men in the band is considered a coward, and publicly shamed:

“Suddenly three older women stepped out of the dark outer circle. Each had been widowed when her husband had been killed in battle. Each had been left crying when her son had followed his father to the land beyond. … the middle woman carried a full war bonnet before her. …they turned their steps directly toward the great boaster, the toucher of dead enemies, and to him they presented the bonnet. …

“Would the coward run out of the circle? If he did, he would be banned forever from the tribe and become an outcast. If he accepted the bonnet, he wold have to go on the war trail at once, not returning until he could bring back proof that he was a man and a warrior. …

“Very slowly, he reached for the bonnet, took it, and with bowed head left the circle.

“There was one other way in which a bonnet could be given as a challenge. from time to time, for various reason, two families within the tribe feud. Each family always tried to get the better of the other, especially in public. These feuds could last a long time before they came to a climax. On a night when the tribe had gathered for a dance, a member of one of the feuding families might step forward and present a bonnet to the young son of the other lodge.

“The challenge was a brutal one, for it offered no escape. The youth had to join the next war party that was formed. …

“War societies, which were somewhat like men’s club, existed among the various tribes. The members were warriors of proven merit, and they were usually grouped by age. Often the members of a war society carried shields bearing the same designs, and on the war trail they gave the same war cry. …

Pehriska-Ruhpa of the Dog Society of the Hidatsa tribe of Native Americans

“Among the Plains Indians the best bow makers were the Sioux and the Crow. …

“A lance bent at the top like a shepherd’s crook and wrapped in otter fur was the insignia of the Dog Soldiers, the Sioux tribal police. This society, made up of the bravest men of the village, ran the buffalo hunts, making sure no one started toward the herd until the proper signal was given. The members kept an eye on the sometimes hotheaded young men, to prevent hem from sneaking out of camp on horse-raiding expeditions. They kept order during ceremonies and, in general, acted to enforce the tribal laws.

“In battle the Dog Soldiers held the foremost position. …

“When the tied of battle turned against them, these great warriors dismounted and jabbed the sharp point of their lance through the trailing sash [that they wore.] Anchored to the ground by it, a Dog Soldier stood and fought to the end. Only a man of his own tribe could free him, and one who freed himself would be forever disgraced and dishonored. …

EvX: Among Indians, the Sioux and tribes similar to them seem closest to our stereotypical idea of the “Wild West Indian.”

Anthropology Friday: Hofsinde Gray-Wolf’s Indian Series: Winter Camping

Robert Hofsinde Gray-Wolf

My apologies for the recent lack of a formal Anthropology Friday–I just haven’t found much worth sharing lately. Luckily my bad luck reversed with the discovery of Hofsinde Gray-Wolf’s series of books about Native American culture.

According to the University of Southern Mississippi’s de Grummond Children’s Literature Project:

Robert Hofsinde was born in Denmark in 1902 and came to the United States twenty years later… On a painting trip in the north woods of Minnesota, Hofsinde came upon a young Ojibwa (Chippewa) Indian boy who had fallen into a pit trap and severely broken his leg. Hofsinde rescued the boy, set his leg, and carried him back to his village on a sled. In gratitude, the boy’s family adopted Hofsinde and gave him the name Gray-Wolf.

Time spent with the Ojibwa Indians changed the direction of Hofsinde’s career. He began to sketch the Indians and became so interested in their culture that for three years he stayed with the Ojibwa people. Over the next decade Hofsinde visited and studied Indian villages throughout the West and Southwest, painting and writing magazine articles about Indian culture. In the 1940s he and his wife Geraldine (whose Indian name was Morning-Star) began performing an Indian lore program for school children around the nation.

In the mid-1940s Hofsinde took his drawings to Morrow Junior Books, hoping to become a book illustrator. An editor suggested he write a book to supplement his own illustrations. The result was the well-received The Indian’s Secret World (1955). Hofsinde followed up with Indian Sign Language, and eventually wrote and illustrated thirteen more books over the next twenty year… Hofsinde died in 1973.

I doubt Hofsinde ever thought of himself as an anthropologist, but this is obviously no strike against him. The 40s and 50s were the golden age of American interest in everything Indian, and Hofsinde’s books are a pleasant example of the genre. I only regret that I only purchased a few of the books from the set in the shop, and now the rest are gone.

These are children’s books, but still informative. Today we’ll be looking at his Indian Fishing and Camping. Amazon provides a useful summary:

Only in our wilderness areas can we still see the country as the Indian saw it. Most of us find romance in this idea, but few of us know how to carry it out. In this book Robert Hofsinde tells us how we can fish and camp as the Indians did and how we can make the gear that they used. The Indians learned to make their fishing equipment from the natural materials they found around them. They obtained cordage from roots, fibers, and the inner bark of trees. Mr. Hofsinde shows how the Pacific Coast Indians fashioned their fish traps out of this cordage and describes the many ways other Indian groups put it to use. He also includes a chapter on Eskimo ice fishing, clear directions for making such equipment as hooks, spears, and spinners, and instructions for cleaning and cooking one’s catch. Exact, lovely illustrations by the author increase the usefulness of this book. It will add to the pleasure and safety of the modern camper and to the knowledge of anyone interested in Indian lore.

As usual, I will be using “” instead of blockquotes for the parts quoted from Hofsinde.

Winter Fishing:

“In the treeless arctic the winters are long and the summers are so short that even the hardiest berries often fail to ripen fully. The rivers and inlets, even large portions of the sea, are frozen over during nine months of the year. Even so, fishing provided much of the Eskimo’s food. He caught trout, whitefish, and salmon through holes cut in the ice and through the natural cracks that formed int he ice close to shore. Such fishing called for a great deal of skill and patience. When the fish ran in plenty, it did not take a man long to catch more than he needed. On day when the fish had taken to deeper waters, the fisherman often tried one hole after another and, at the end of the day, arrived home with only one or two small fish, or even with none at all.”

EvX: I am reminded here of the descriptions in Ingold’s Hunters, Pastoralists, and Ranchers of the variability of reindeer hunting economies–some years the hunters can kill a whole herd of migrating deer and so in one day provide for their needs for for many months, and some years the hunters miss the herd by a few miles, resulting in famine.

“Fishing through the ice also had its elements of danger, especially when it was done far from shore. A sudden change of wind or a sudden rise in temperature might cause large ice floes to break away. If this happened while a fisherman was intent upon his work, it was not uncommon for him to drift out into open water, and no one ever saw him again. …

“To protect himself from [the icy winds] at his fishing hole, the Eskimo at times put up a shelter. Such a shelter was usually nothing more than a large animal hide hung over a tripod made from driftwood. In addition to sheltering him a little, it also gave him a dark interior, which helped him to see deeper into the water. …

Netsilik man fishing with spear in hand

“Sheltered or not, the ice fisherman still has a two-handed job. He must hold his line and lure in one hand and the spear in his other. At the moment the fish comes to the lure, he must strike fast and spear it. This is the thrill of the game.

“The Eskimo used an entirely different type of fishing gear from that of other Indians. …

“The Eskimo usually made his fishing rod from a piece of driftwood fourteen inches long. Whittled into a flat shape, it had a deep notch cut into each end. At one end the fishing line was fastened. When not in use, the line was wound around the rod lengthwise, with the notches holding it in place.

“The fishline was made of whale bone. This type of bone did not come from the skeleton of the whale, but from the flexible, comb-like baleen strip, which is the food strainer found in the mouth of the toothless blue whale and the right whale. The baleen was split into very fine strands, which never kinked. When ice formed on the wet line, a quick shake snapped it off.

“On the free end of the line the Eskimo tied a small jigger, or lure, crafted from a piece of bone or ivory. These pieces usually represented very small fish or, most often, shrimp. …

“The scoop net was very important. With it the Eskimo fisherman scooped loose pieces of ice out of his fishing hole. It was also used to keep the hole open, for in the cold air new ice formed rapidly over the open water. The net, too, was made from baleen strips. The hoop from which the net hung was formed from a sliver of moose antler that had been boiled in water until pliable and then bent into shape. …

“In the winter these scoops were carried everywhere by the villagers, and although they had been designed for one purpose originally, the Eskimo boys invented a new use for them. They became quite expert at picking up a scoopful of snow and throwing it with a great deal of force and accuracy at any a chosen target.

“An equally useful article was the spear… When a fish was attracted to the lure dangling just below the water line, the Eskimo struck down quickly with the poised spear. This quick thrust impaled the fish on the center prong. …

“The Eskimos ice fished with a single baited copper hook or with a four-pronged ivory jigger. These were the earliest, pre-European fishhooks, and they were made without barbs from copper found on the surface of the ground or in veins in the earth. An Eskimo bent up a thin piece of copper to form a hook, which was a little at the bottom than at the top. …

“A barbless hook was necessary in the arctic. In that cold climate a fish froze slid almost the instant it was brought out of the water. When an Eskimo caught a fish on his barbless hook, he could dislodge it with a deft jerk without removing his mittens, so his hands remained perfectly dry.

Here’s a good illustration of the two-handed line-reeling technique

“The Eskimo also never touched his wet fishline, even when he pulled it in. Holding the short fishing rod in one hand and his ice scoop in the other, he lifted part of the line with the scoop, the next part with the rod. He alternated between the scoop and the rod, cisscrossing, until he had wound up the entire line and had pulled the fish out of the hole onto the ice.

“One fish the Eskimos caught in warmer weather was the salmon. During the summer, when the salmon migration was on and they passed through the shallow arctic streams to spawn, the Eskimo fishermen blocked their way with large boulders. As the fish darted about in an effort to reach open water, they walked among them and speared them by the hundreds.”

On the more general subject of camping:

“The Indians were camping long before the Europeans came to America. Some of them had permanent villages. Others, such a the Plains Indians, moved their camps as they followed the buffalo The woodland Indians made their camps throughout the forest, as they gathered berries and maple sap or went fishing. These early camps were not like the vacation camps we know today, but were places where work had to be done constantly. Canoes needed patching, a new paddle was required, buckskin clothing had to be mended, and other seemingly endless tasks had to be performed.

Voyageurs at Dawn, by Frances Anne Hopkins, 1871

“Camping was still hard work when Lewis and Clark and the men of their expedition explored the West from 1804 to 1806. Night after night, wherever the end of of the day found them, they set up camp, checked over their equipment, cooked their rations, and slept–often in a pouring rain. Shelters and sleeping bags were unknown. They had no portable stoves or lanterns. In fact, each man’s gear was held to a minimum.

“The Canadian voyageurs also camped at night along their watery highways. We can be sure that they slept well, for according to some of their old journals, their day started at 2:30 in the morning and ended at 8:00 in the evening, with only a rest now and again for ‘a pipe.'”

EvX: According to Wikipedia:

The voyageurs were French Canadians who engaged in the transporting of furs by canoe during the fur trade years. Voyageur is a French word, meaning “traveler”. The emblematic meaning of the term applies to places (New France, including the Pays d’en Haut and the Pays des Illinois) and times (primarily in the 18th and early 19th centuries) where transportation of materials was mainly over long distances. This major and challenging task of the fur trading business was done by canoe and largely by French Canadians. The term in its fur trade context also applied, at a lesser extent, to other fur trading activities.[1] Being a voyageur also included being a part of a licensed, organized effort, one of the distinctions that set them apart from the coureurs des bois. …

The voyageurs were regarded as legendary, especially in French Canada.[5] They were heroes celebrated in folklore and music. For reasons of promised celebrity status and wealth, this position was very coveted. James H. Baker was once told by an unnamed retired voyageur:

“I could carry, paddle, walk and sing with any man I ever saw. I have been twenty-four years a canoe man, and forty-one years in service; no portage was ever too long for me, fifty songs could I sing. I have saved the lives of ten voyageurs, have had twelve wives and six running dogs. I spent all of my money in pleasure. Were I young again, I would spend my life the same way over. There is no life so happy as a voyageur’s life! [6][7]”

Despite the fame surrounding the voyageur, their life was one of toil and not nearly as glorious as folk tales make it out to be. For example, they had to be able to carry two 90-pound (41 kg) bundles of fur over portage. Some carried up to four or five, and there is a report of a voyageur carrying seven for half of a mile.[8] Hernias were common and frequently caused death.[7] Most voyageurs would start working when they were twenty two and they would continue working until they were in their sixties. They never made enough money to consider an early retirement from what was a physically grueling lifestyle.[9] …

Music was a part of everyday life for the voyageur. Voyageurs sang songs while paddling and working, as well as during other activities and festivities. Many who travelled with the voyageurs recorded their impressions from hearing the voyageurs sing, and that singing was a significant part of their routine. But few wrote down the words or the music. As a result, records of voyageur songs tend to be skewed towards those that were also popular elsewhere in Canada.[7] Examples of Voyageur songs include “À la claire fontaine” (a favorite), “Alouette“, “En roulant ma boule“, “J’ai trop grand peur des loups“, and “Frit à l’huile“. Another such song is titled “C’est l’aviron qui nous mène”. It goes as follows:

M’en revenant de la joli’Rochelle, J’ai rencontré trois jolies demoiselles, C’est l’aviron qui nous mèn’, qui nous mont’

C’est l’aviron qui nous monte en haut.[31]

To this day, school children learn this song as part of French Canadian culture. These songs served a dual purpose for the voyageurs. Not only would they be entertaining during long voyages but their rhythm would help synchronize their paddling.[32] One fur trader, Edward Ermatinger, had the forethought to record some of these songs. This is how eleven voyageurs songs came to be known today. Ermatinger travelled for the Hudson’s Bay Company from 1818 to 1828 as a clerk and learned these songs firsthand. These came to light only in 1943 when the Ermatinger family archives provided them to the Public Archives of Canada so that they may be copied.[33] …

La Chasse-galerie by Henri Julien

La Chasse-galerie, also known as “The Bewitched Canoe” or “The Flying Canoe,” is a popular French-Canadian tale of voyageurs who make a deal with the devil in order to visit their sweethearts during the night, who are located a long distance away. It is a variant of the Wild Hunt. Its most famous version was written by Honoré Beaugrand (1848–1906). It was published in The Century Magazine in August 1892. More recently, the Quebec brewery Unibroue has incorporated a version of the legend into the name and artwork of its highly respected strong ale, Maudite (“Damned”).[34]

EvX: It annoys me when people claim that back in the fifties, books/media about Indians were just a mish-mash of stereotypes without respect for the differences of individual tribes. They talk about fifties books/media as though it were all terrible and insulting, with no regard for the quality works nor the value of popular interest in Indian cultures. Today the whole idea of reading about and being interested in Indians is deprecated. I think this attitude does more harm than good, because people are much more likely to protect and care about people they’re interested in than people they hardly ever hear about.

 

The Modern Ainu, pt 2

Welcome back, everyone. Yesterday we were discussing Ainu genetics. Today we’re still discussing Ainu genetics, but this time we’re discussing mtDNA instead of Y DNA.

Modern Ainu (political protest) in 1992

Based on analysis of one sample of 51 modern Ainus, their mtDNA lineages have been reported to consist mainly of haplogroup Yhaplogroup Dhaplogroup M7a … and haplogroup G1[49][52][53] Other mtDNA haplogroups detected in this sample include A (2/51), M7b2 (2/51), N9b (1/51), B4f (1/51), F1b (1/51), and M9a (1/51). Most of the remaining individuals in this sample have been classified definitively only as belonging to macro-haplogroup M.[52] According to Sato et al. (2009), who have studied the mtDNA of the same sample of modern Ainus (n=51), the major haplogroups of the Ainu are N9 (14/51 = 27.5%, including 10/51 Y and 4/51 N9(xY)), D (12/51 = 23.5%, including 8/51 D(xD5) and 4/51 D5), M7 (10/51 = 19.6%), and G (10/51 = 19.6%, including 8/51 G1 and 2/51 G2); the minor haplogroups are A (2/51), B (1/51), F (1/51), and M(xM7, M8, CZ, D, G) (1/51).[54]

Note that Y (confusingly named) is a sub-haplogroup of N9. It’s commonly found in groups around the Sea of Okhotsk, (including the Ainu,) and in Indonesia, similar to the distribution of Sundadont teeth. Haplogroup D is found in Native Americans (highest frequency among the Aleuts,); Siberians, Ainu, east Asians, Japanese, etc. M7 is kind of generically east-Asian, with high frequency in Japan. In other words, Ainu maternal DNA is fairly similar to that of Japan at large + nearby Siberians.

So how closely related are the Ainu to rest of the Japanese?

Given the archaeology of the area and what we now know of the genetics, it looks like the Ainu were descended primarily from two main groups:

  1. Jomon, (the ancient people of Japan,)
  2. Nearby Siberians, (eg, the Nivkhs.)

Over the past hundred years or so, though, the Ainu have purposefully intermarried with the non-Ainu Japanese, who are themselves descended from a mix of:

  1. Jomon
  2. Yayoi, who invaded around 300 BC, conquering the Jomon.

We’d expect therefore for the Ainu and Japanese to share a fair amount of their mtDNA (the Yayoi probably absorbed Jomon women into their groups;) but not much Y DNA. According to Wikipedia:

Studies published in 2004 and 2007 show the combined frequency of M7a and N9b were observed in Jomons and which are believed by some to be Jomon maternal contribution at 28% in Okinawans (7/50 M7a1, 6/50 M7a(xM7a1), 1/50 N9b), 17.6% in Ainus (8/51 M7a(xM7a1), 1/51 N9b), and from 10% (97/1312 M7a(xM7a1), 1/1312 M7a1, 28/1312 N9b) to 17% (15/100 M7a1, 2/100 M7a(xM7a1)) in mainstream Japanese.[55][56]

A recent reevaluation of cranial traits suggests that the Ainu resemble the Okhotsk more than they do the Jōmon.[57] This agrees with the reference to the Ainu being a merger of Okhotsk and Satsumon referenced above.

Now certainly, if we can use DNA testing to tell that someone is “half Spaniard, a quarter Finnish, and a quarter Czech, with 3% Neanderthal DNA,” then we can use DNA testing to tell what %s of someone’s ancestry are Japanese, Ainu, Jomon, Yayoi, Siberian, etc.–it’s just a matter of getting enough relevant samples. The only major issue I could see getting in the way is if there actually is no such thing as a genetically “pure” Ainu, but rather a bunch of small Ainu groups with varying levels of admixture from all of the other groups. For example, there is no such thing as “Turkic” genetics–all “Turkic” groups speak Turkic languages, take great pride in being Turkic, and presumably have cultural connections, but genetically they are quite diverse. The situation is similar with Jewish groups. 2000 years ago, most Jews were genetically “Jewish,” but today, the vast majority of Jews are at least 50% non-ancient Hebrew by DNA.

From Ingold

 

But of course, genetics doesn’t tell you much about the lives of modern Ainu.

Many people theorize recent connections between all of the peoples along the north Pacific rim, from Japan to Oregon, and northward across Canada, based on similar abstract, geometric art styles; lifestyles; and documented contacts. The eternally-controversial Kennewick man (a 9,000 year old skeleton discovered in Washington State,) was initially described by some anthropologists as resembling an Ainu man. Mister Kennewick has since been proven to be related to modern Native Americans–Native Americans may simply have looked different 9,000 years ago.

I look forward to more research on connections between circum-polar and circum-Pacific peoples.

For further reading and interesting photos, I recommend The Ainu and their Culture by Dubreuil.

By Request: The Modern Ainu pt 1

Old photograph of an Ainu man

Most of the information easily available on the internet speaks of the Ainu in the past tense: The Ainu were hunter-gatherers; the Ainu worshiped; the Ainu were conquered. The photographic situation is similar: an image search for “Ainu” brings up a few dozen century-old photos and not much else.

But the modern Ainu, of course, do not live in the past–they live in today, primarily in the very modern city of Sapporo. The modern Ainu are not hunter-gatherers (although the entire nation of Japan remains highly dependent on fishing for its nutrition;) they are doctors and shop-keepers, office workers and artists. They go to school, keep up with modern fashions, play video games, and ride the shinkansen just like everyone else in Japan.

Wikipedia (and everyone else) estimates that about 25,000 Ainu live today in Japan, with the caveat that since the Ainu don’t always bother to mention their ancestry, there could be a couple hundred thousand who just haven’t been counted.

Due to years of inter-marrying, the vast majority of today’s Ainu are at least part Japanese. One reference I recall estimated that about 300 pure-blooded Ainu remained in 1950; another estimated that 200 remain today.

There are also some Ainu living in Russia; according to Wikipedia, about 100 Russians tried to identify as Ainu in the 2010 census, and nearly a thousand people with some degree of Ainu ancestry live in the area.

Alas for my purposes as a writer, these few remaining folks appear to be living their lives out in anthropological anonymity, rather than posting selfies tagged #RealAinu all over the internet.

The one thing everyone likes to argue about in threads about the Ainu is whether or not they look like white people.

It’s kind of dumb to fight about, since obviously Ainu look like Ainu.

Okay, okay. Don’t start a flame war. According to Wikipedia:

Cavalli-Sforza places the Ainu in his “Northeast and East Asian” genetic cluster.[42] …

Turner found remains of Jōmon people of Japan to belong to Sundadont pattern similar with the Southern Mongoloid living populations of Taiwanese aborigines, Filipinos, Indonesians, Thais, Borneans, Laotians, and Malaysians. …

Genetic testing has shown them to belong mainly to Y-haplogroup D-M55.[49] Y-DNA haplogroup D2 is found frequently throughout the Japanese Archipelago including Okinawa. The only places outside Japan in which Y-haplogroup D is common are Tibet in China and the Andaman Islands in the Indian Ocean.[50]

Your Y-haplogroup traces your paternal ancestry, because men (and only men) inherit their Y-chromosomes from their fathers. Your M or Mt-DNA, (short for mitochondrial DNA,) hails exclusively from your mother (and both men and women have Mt-DNA, because we all have mitochondria.)

Often when one group of people conquers another group of people, their descendants end up with Y-DNA from the conquerors and MtDNA from the conquered, but there are other ways people come together, like folks intermarrying with their neighbors.

(Presumably this study was done with relatively pure-blooded Ainu.)

The distribution of Haplogroup D-M174 is quite suggestive: Ainu, Tibetans, and Andaman Islanders. These are three (historically) highly isolated groups–one of the world’s few remaining basically uncontacted peoples, the Sentinelese, (they’ll put a spear in you if you land on their island) live in the Andaman Islands. The Tibetans, as I’ve mentioned, have inherited DNA from the Denisovans–cousins of the Neanderthals who interbred with their ancestors–that lets them breathe more easily at high altitudes than anyone else on Earth, making it rather hard for non-Tibetans move there, much less conquer and occupy it [Note: I wouldn’t be surprised if the Nepalese or other folks who also live up in the Himalayas also have the adaptation; this isn’t meant to be a discussion of modern political borders.] And the Ainu basically live on the far edge of Asian at the southern edge of Siberia–northern Japan is the snowiest populated place in the world.

“Sinodont” and “sundadont” actually refer to two different tooth shapes.

East Asian genetic tree, showing Ainu, Japanese, Koreans, etc

Tibetans and Andaman Islanders are definitely Asians–they clade with other Asians in the Greater Asian Clade–but they don’t look much alike. You wouldn’t mistake them for Caucasians, though.

Haplogroup D-M174 is believed to have evolved about 50-60-thousand years ago, presumably in Asia. This was shortly after the Out-of-Africa event, which occurred about 70,000 (or possibly 100,000 years ago [there might have been more than one OOA.]) D-M174 is so old that its “parent” haplogroup is DE, which is found in Africa and Asia.

By contrast, the mutation to the EDAR-gene which gives Han Chinese (the Asian ethnic group Americans are most familiar with) and Japanese their characteristic hair, skin, tooth shape, build, etc., (EDAR is pretty incredible in that way) only occurred 30,000 years ago–that is, the Ainu split off from other Asians 20-30 thousand years before what we think of as “the Asian look” had even evolved.

For that matter, Caucasian themselves only appear to have split off from Asians around 40,000 years ago–10,000 years before EDAR mutated, but 10-20,000 years after D-M174 arose.

Or to put it another way:

About 70,000 years ago, an intrepid band of explorers left Africa. Presumably, these people looked African, but I don’t know exactly which Africans these ancient people looked like–perhaps they didn’t really look like any modern group; perhaps they looked a lot like most Sub-Saharan Africans; perhaps they looked like the Bushmen, noted for their tawny skin tones and more “Asian” look than other Sub-Saharans. I don’t know yet.

About 60,000 years ago, the band split, and one group spread far across Asia. Their modern descendants are the Ainu, Tibetans, and Andaman Islanders.

The other group presumably hung out in central Eurasia, until about 40,000 years ago, when it definitively split. One group went west and became the Caucasians; the other became the Han.

Around 30,000 years, the distinctive EDAR mutation that gives east-Asians their “typical” appearance evolved.

Around 10,000 years ago, more or less, Europeans began getting lighter, and “whiteness” as we know it evolved.

Oki Kano, Ainu Musician

So… could the Ainu retain some traits or have never obtained some traits–like epicanthic folds at the corners of their eyes–which make them look more like their ancestral group, to which the ancestors of both Asians and Caucasians belonged? Sure. Could they have just evolved traits to deal with the extremely cold, near-Siberian environment they lived in that happened to resemble traits that evolved in European populations dealing with a similarly cold environment? Sure.

But are they Caucasians? Not even remotely.

And in my opinion, they don’t look Caucasian, at least not when their faces aren’t covered with big, bushy beards. (The modern Ainu tend to shave.) Take, for example, Oki Kano, an Ainu musician. Nothing about his appearance says, “Mysterious tribe of lost Caucasians.”

Back to Wikipedia:

In a study by Tajima et al. (2004), two out of a sample of sixteen (or 12.5%) Ainu men have been found to belong to Haplogroup C-M217, which is the most common Y-chromosome haplogroup among the indigenous populations of Siberia and Mongolia.[49] … Some researchers have speculated that this minority of Haplogroup C-M217 carriers among the Ainu may reflect a certain degree of unidirectional genetic influence from the Nivkhs, a traditionally nomadic people of northern Sakhalin and the adjacent mainland, with whom the Ainu have long-standing cultural interactions.[49]

The Nivkhs live basically next door and have a lot of cultural similarities–for example, both groups traditionally had shamanic rituals involving bears, which they raised and then sacrificed:

Nivkh Shamans also presided over the Bear Festival, a traditional holiday celebrated between January and February depending on the clan. Bears were captured and raised in a corral for several years by local women, treating the bear like a child.[34] The bear was considered a sacred earthly manifestation of Nivkh ancestors and the gods in bear form (see Bear worship). During the Festival, the bear would be dressed in a specially made ceremonial costume. It would be offered a banquet to take back to the realm of gods to show benevolence upon the clans.[29] After the banquet, the bear would be sacrificed and eaten in an elaborate religious ceremony. Often dogs were sacrificed as well. The bear’s spirit returned to the gods of the mountain ‘happy’ and would then reward the Nivkh with bountiful forests.[35]

A very similar ceremony, Iomante, is practiced by the Ainu people of Japan.

While haplogroup D-M174 shows affinity with more southerly Asian groups, like the Tibetans or Andaman Islanders, haplogroup C-M217 is found throughout northern Asia (principally Siberia) and northern North America.

To be continued…

What Mental Traits does the Arctic Select for?

Apropos Friday’s conversation about the transition from hunting to pastoralism and the different strategies hunters employ in different environments, I got to thinking about how these different food-production systems could influence the development of different “intelligences,” or at least mental processes that underlie intelligence.

Ingold explains that in warm climes, hunter-gatherers have many food resources they can exploit, and if one resource starts running low, they can fairly easily switch to another. If there aren’t enough yams around, you can eat melons; if not enough melons, squirrels; if no squirrels, eggs. I recall a study of Australian Aborigines who agreed to go back to hunter-gatherering for a while after living in town for several decades. Among other things (like increased health,) scientists noted that the Aborigines increased the number of different kinds of foods they consumed from, IIRC, about 40 per week to 100.

By contrast, hunters in the arctic are highly dependent on exploiting only a few resources–fish, seals, reindeer, and perhaps a few polar bears and foxes. Ingold claims that there are (were) tribes that depended largely on only a few major hunts of migrating animals (netting hundreds of kills) to supply themselves for the whole year.

If those migrating change their course by even a few miles, it’s easy to see how the hunters could miss the herds entirely and, with no other major species around to exploit, starve over the winter.

Let’s consider temperate agriculture as well: the agriculturalist can store food better than the arctic hunter (seal meat does not do good things in the summer,) but lacks the tropical hunter-gatherer’s flexibility; he must stick to his fields and keep working, day in and day out, for a good nine months in a row. Agricultural work is more flexible than assembly line work, where your every minute is dictated by the needs of the factory, but a farmer can’t just wander away from his crops to go hunt for a months just because he feels like it, nor can he hope to make up for a bad wheat harvest by wandering into his neighbor’s fields and picking their potatoes.

Which got me thinking: clearly different people are going to do better at different systems.

But first, what is intelligence? Obviously we could define it in a variety of ways, but let’s stick to reasonable definitions, eg, the ability to use your brain to achieve success, or the ability to get good grades on your report card.

A variety of mental traits contribute to “intelligence,” such as:

  1. The ability to learn lots of information. Information is really useful, both in life and on tests, and smarter brains tend to be better at storing lots and lots of data.
  2. Flexible thinking. This is the ability to draw connections between different things you’ve learned, to be creative, to think up new ideas, etc.
  3. Some form of Drive, Self Will, or long-term planning–that is, the ability to plan for your future and then push yourself to accomplish your goals. (These might more properly be two different traits, but we’ll keep them together for now.)

Your stereotypical autistic, capable of memorizing large quantities of data but not doing much with them, has trait #1 but not 2 or 3.

Artists and musicians tend to have a lot of trait #2, but not necessarily 1 or 3 (though successful artists obviously have a ton of #3)

And an average kid who’s not that bright but works really hard, puts in extra hours of effort on their homework, does extra credit assignments, etc., has a surfeit of #3 but not much 2 or 1.

Anyway, it seems to me like the tropical hunting/gathering environment, with many different species to exploit, would select for flexible thinking–if one food isn’t working out, look for a different one. This may also apply to people from tropical farming/horticulturalist societies.

By contrast, temperate farming seems more likely to select for planning–you can’t just wander off or try to grow something new in time for winter if your first crop doesn’t work out.

Many people have noted that America’s traditionally tropical population (African Americans) seems to be particularly good at flexible thinking, leading to much innovation in arts and music. They are not as talented, though, at Drive, leading to particularly high highschool dropout rates.

America’s traditionally rice-farming population (Asians,) by contrast, has been noted for over a century for its particularly high drive and ability to plan for the future, but not so much for contributions to the arts. East Asian people are noted for their particularly high IQ/SAT/PISA scores, despite the fact that China lags behind the West in GDP and quality of life terms. (Japan, of course, is a fully developed country.) One potential explanation for this is that the Chinese, while very good at working extremely hard, aren’t as good at flexible thinking that would help spur innovation. (I note that the Japanese seem to do just fine at flexible thinking, but you know, the Japanese aren’t Chinese and Japan isn’t China.)

(I know I’m not really stating anything novel.) But the real question is:

What kind of mental traits might pastoralism, arctic pastoralism, or arctic hunting select for?

Cold Winter Theory in Non-Human Animals:

With regards to birds, brain size and ecology, there is a problem. Birds living in the high latitudes must either adapt a migrating behavioral pattern or learn how to survive in the winter. Most birds take the first route, but some don’t. However, to fly long distances, it helps to be lean, so there is strong selection against extra weight such as a larger brain. For this reason, bivariate latitude x brain size comparisons might show the opposite pattern than expected. One must account for the solution to the, well, cold winter problem. Some amphibians have an analogous tactic: hibernation. Many insects have yet another analogous solution: they only live in the summer (single year life spans). As far as I understand, fish do not have issues with the water temperature in the winter, so they don’t face the problem. Except for possibly hibernation (which sometimes does require planning ability e.g. in squirrels), these strategies would not seem to select so strongly for intelligence, and so one would not expect the higher latitude species to smarter, less aggressive and so on.

In general, therefore, it seems best to focus on animals that tackle the cold winter problem head-on instead of avoiding it somehow (migrate, hibernate, or single-year lifespans). Among birds, the smartest birds are of the Corvidae family — in particular crows, ravens and magpies — and they generally don’t migrate in the winter. Of the non-Corvidae, I think the smartest birds are some of the parrot species. These also often don’t migrate. (See also bird intelligence.) …

Exposure to Junk Food is Causing Obesity in Siberian Tribes:

The first-ever cases of obesity have been recorded among nomadic Arctic reindeer herders, after they became exposed to instant noodles and other junk foods.

Russian scientists are warning about the dramatic change in the Nenets and Khanty peoples on the icy Yamal peninsula in northern Siberia, who for centuries had eaten only traditional foods.

A diet based on venison and fresh river fish meant that obesity was unknown among these indigenous peoples, but now outside influences are changing everything. …

Human Behavior as a Long-Term Ecological Driver of Non-Human Evolution:

Due to our intensive subsistence and habitat-modification strategies—including broad-spectrum harvesting and predation, widespread landscape burning, settlement construction, and translocation of other species—humans have major roles as ecological actors who influence fundamental trophic interactions. … Clear examples of anthropogenic effects on non-human morphological evolution have been documented in modern studies of substantial changes to body size or other major traits in terrestrial and aquatic vertebrates, invertebrates, and plants in response to selective human harvesting, urbanized habitats, and human-mediated translocation. Meanwhile, archaeological records of harvested marine invertebrates and terrestrial vertebrates suggest that similar processes extend considerably into prehistory, perhaps to 50,000 yr BP or earlier. These results are consistent with palaeoenvironmental and other records that demonstrate long-term human habitat modification and intensive harvesting practices. …

Comment of the Week goes to BaruchK:

For a personal narrative of what happens when a very refined and compassionate culture encounters such starvation that mothers eat their own children, you can look at our Book of Lamentations.

It makes for very hard, heartbreaking reading, but necessary.

… G-d certainly has compassion. The way we understand the degradation described in the Book of Lamentations is that it is a just punishment and reflection for spiritual degradation we imposed upon ourselves through idolatry (more on this below).

> In Carthage “[child] sacrifice in the ancient world reached its infamous zenith.”

Perfect example of why r/k is not a good model for people. Also see Stove’s Evolutionary Fairytales (available online in pdf for free.) People are not cod fish or elephants.

Allow me to make a counter-proposal.

The Carthaginians, Aztecs etc. were not welfare troglodytes. They were not Russian peasants, who had had their grain requisitioned. And they were not the besieged and starving population of Jerusalem. They were a highly refined society with an aristocracy, literacy, and a high investment in their upper classes. They were also cruel and vile people. They did not sacrifice their children out of physical need, but rather out of idolatry, which is to say, the projection of one’s own egotistic desires and fears upon an external object which represents an imaginary deity, which is supposed to serve you. …

And Jefferson and FlockofLambs left good thoughts on Cost Disease:

J: There is a more explicitly anthropological argument to be made here, as well. All of the institutions, cultural artifacts, and policies that could be conserved grew up over centuries of agriculture. We haven’t really developed solid cultural tools to deal with industrialization, and we’re already done with it. The left plays the “it’s not relevant anymore” game, and discards important tools, but we don’t have anything to replace them with. …

FoL: So i think Scott simplified Baumol’s Cost Disease, and it gets simplified further here. The point isn’t that “the cost of things goes up” but “when the productivity of some things goes up, the cost of things with similar inputs goes up, even if their quality does not.”

Cannibalism, Abortion, and R/K Selection.

Reindeer herder, from "Quarter of a Million Reindeers to be Butched... after Anthrax Outbreak" : "Serbian officials have demanded a huge cull of a 250,000 reindeers by Christmas over the risk of an anthrax outbreak. Currently 730,000 animals are being kept in the Yamal Peninsula and the rest of the Yamalo-Nenets region."
Reindeer herder, from Quarter of a Million Reindeers to be Butched… after Anthrax Outbreak: “Currently 730,000 animals are being kept in the Yamal Peninsula and the rest of the Yamalo-Nenets region.”

In Hunters, Pastoralists, and Ranchers: Reindeer Economies and their Transformations [PDF,] Ingold describes the social distribution of food among hunter-gatherers. In normal times, when food is neither super-abundant nor scarce, each family basically consumes what it brings in, without feeling any particular compulsion to share with their neighbors. In times of super-abundance, food is distributed throughout the tribe, often quite freely:

Since harvested animals, unlike a plant crop, will not reproduce, the multiplicative accumulation of material wealth is not possible within the framework of hunting relations of production. Indeed, what is most characteristic of hunting societies everywhere is the emphasis not on accumulation but on its obverse: the sharing of the kill, to varying degrees, amongst all those associated with the hunter. …

The fortunate hunter, when he returns to camp with his kill, is expected to play host to the rest of the community, in bouts of extravagant consumption.

The other two ethnographies I have read of hunter-gatherers (The Harmless People, about the Bushmen of the Kalahari, and Kabloona, about the Eskimo aka Inuit) both support this: large kills are communal feasts. Hunter gatherers often have quite strict rules about how exactly a kill is to be divided, but the most important thing is that everyone gets some.

And this is eminently sensible–you try eating an entire giraffe by yourself, in the desert, before it rots.

Even in the arctic, where men can (in part of the year) freeze food for the future, your neighbor’s belly is as good as a freezer, because the neighbor you feed today will feed you tomorrow. Hunting is an activity that can be wildly successful one day and fail completely the next, so if hunters did not share with each other, soon each one would starve.

Whilst the successful hunter is required to distribute his spoils freely amongst his camp fellows, he does so with the assurance that in any future eventuality, when through bad luck he fails to find game, or through illness or old age he can no longer provide for himself and his family, he will receive in his turn. Were each hunter to produce only for his own domestic needs, everyone would eventually perish from hunger (Jochelson 1926:124). Thus, through its contribution to the survival and reproduction of potential producers, sharing ensures the perpetuation of society as a whole. …

Yet he is also concerned to set aside stocks of food to see his household through at least a part of the coming winter. The meat that remains after the obligatory festive redistribution is therefore placed in the household’s cache, on which the housewife can draw specifically for the provision of her own domestic group (Spencer 1959:149). After the herds have passed by, domestic autonomy is re-establisheddraws on its own reserves of stored food.

But what happens at the opposite extreme, not under conditions of abundance, but when everyone‘s stocks run out? Ingold claims that in times of famine, the obligation to share what little food one has with one’s neighbors is also invoked:

We find, therefore, that the incidence of generalized reciprocity tends to peak towards the two extremes of scarcity and abundance… The communal feast that follows a successful hunting drive involves the same heightening of band solidarity, and calls into play the same functions of leadership in the apportionment of food, as does the consumption of famine rations.

I am reminded here of a scene in The Harmless People in which there was not enough food to go around, but the rules of distribution were still followed, each person just cutting their piece smaller. Thomas described one of the small children, hungry, trying to grab the food bowl–not the food itself–to stop their mother from giving away their food to the next person in the chain of obligation.

Here Ingold pauses to discuss a claim by Sahlins that such social order will (or should) break down under conditions of extreme hunger:

Probably every primitive organization has its breaking-point, or at least its turning-point. Every one might see the time when co-operation is overwhelmed by the scale of disaster and chicanery becomes the order of the day. The range of assistance contracts progressively to the family level; perhaps even these bonds dissolve and, washed away, reveal an inhuman, yet most human, self-interest. Moreover, by the same measure that the circle of charity is
compressed that of ‘negative reciprocity* is potentially expanded. People who helped each other in normal times and through the first stages of disaster display now an indifference to each others’ plight, if they do not exacerbate a mutual downfall by guile, haggle and theft.

Ingold responds:

I can find no evidence, either in my reading of circumpolar ethnography, or in the material cited by Sahlins, for the existence of such a ‘turning-point’ in hunting societies. On the contrary, as the crisis deepens, generalized reciprocity proceeds to the point of dissolution of domestic group boundaries. ‘Negative reciprocity’, rather than closing in from beyond the frontiers of the household, will be expelled altogether from the wider social field, only to make its appearance within the heart of the domestic group itself.

Thus the women of the household, who are allowed to eat only after the appetites of their menfolk have been satisfied, may be left in times of want with the merest scraps of food. Among the Chipewyan, ‘when real distress approaches, many of them are permitted to starve, when the males are amply provided for’…

In situations of economic collapse, negative reciprocity afflicts not only the domestic relations between husband and wife, but those between mother and child, and between parent and grandparent. If the suckling of children is the purest expression of generalized reciprocity, in the form of a sustained one-way flow, then infanticide must surely represent the negative extreme. Likewise, old or sick members of the household will be the first to be abandoned when provisions run short. Even in normal times, individuals who are past labour have to scavenge the left-overs of food and skins (Hearne 1911:326). In the most dire circumstances of all, men will consume their starving wives and children before turning upon one another.

Drawing on Eskimo material, Hoebel derives the following precepts of cannibal conduct: Not unusually . . . parents kill their own children to be eaten. This act is no different from infanticide. A man may kill and eat his wife; it is his privilege. Killing and eating a relative will produce no legal consequences. It is to be presumed, however, that killing a non-relative for food is murder. (1941:672, cited in Eidlitz 1969:132)

In short, the ‘circle of charity’ is not compressed but inverted: as the threat of starvation becomes a reality, the legitimacy of killing increases towards the centre. The act is ‘inhuman’ since it strips the humanity of the victim to its organic, corporeal substance. If altruism is an index of sociability, then its absolute negation annuls the sodality of the recipient: persons, be they human or animal, become things.

297px-world_population_v3-svgThis is gruesome, but let us assume it is true (I have not read the accounts Ingold cites, so I must trust him, and I do not always trust him but for now we will.)

The cold, hard logic of infanticide is that a mother can produce more children if she loses one, but a child who has lost its mother will likely die as well, along with all of its siblings. One of my great-great grandmothers suffered the loss of half her children in infancy and still managed to raise 5+ to adulthood. Look around: even with abortion and birth control widely available, humanity is not suffering a lack of children. ETA: As BaruchK correctly noted, today’s children are largely coming from people who don’t use birth control or have legal access to abortion; fertility rates are below replacement throughout the West, with the one exception AFAIK of Israel.

c08pnclw8aapot6Furthermore, children starve faster and are easier to kill than parents; women are easier to kill than men; people who live with you are easier to kill than people who don’t.

Before we condemn these people, let us remember that famine is a truly awful, torturous way to die, and that people who are on the brink of starving to death are not right in their minds. As “They’re not human”: How 19th-century Inuit coped with a real-life invasion of the Walking Dead recounts:

“Finally, as the footsteps stopped just outside the igloo, it was the old man who went out to investigate.

“He emerged to see a disoriented figure seemingly unaware of his presence. The being was touching the outside of the igloo with curiosity, and raised no protest when the old man reached his hand out to touch its cheek.

“His skin was cold. …

The figures, of course, were the last survivors of the Franklin Expedition. They had buried their captain. They had seen their ship entombed by ice. They had eaten the dead to survive. …

Inuit nomads had come across streams of men that “didn’t seem to be right.” Maddened by scurvy, botulism or desperation, they were raving in a language the Inuit couldn’t understand. In one case, hunters came across two Franklin Expedition survivors who had been sleeping for days in the hollowed-out corpses of seals. …

The figures were too weak to be dangerous, so Inuit women tried to comfort the strangers by inviting them into their igloo. …

The men spit out pieces of cooked seal offered to them. They rejected offers of soup. They grabbed jealous hold of their belongings when the Inuit offered to trade.

When the Inuit men returned to the camp from their hunt, they constructed an igloo for the strangers, built them a fire and even outfitted the shelter with three whole seals. …

When a small party went back to the camp to retrieve [some items], they found an igloo filled with corpses.

The seals were untouched. Instead, the men had eaten each other. …

In 1854, Rae had just come back from a return trip to the Arctic, where he had been horrified to discover that many of his original Inuit sources had fallen to the same fates they had witnessed in the Franklin Expedition.

An outbreak of influenza had swept the area, likely sparked by the wave of Franklin searchers combing the Arctic. As social mores broke down, food ran short.

Inuit men that Rae had known personally had chosen suicide over watching the slow death of their children. Families had starved for days before eating their dog teams. Some women, who had seen their families die around them, had needed to turn to the “last resource” to survive the winter.

Infanticide, cannibalism, and human sacrifice were far more common prior to 1980 or so than we like to think; God forbid we should ever know such fates.

According to Wikipedia:

“Many Neolithic groups routinely resorted to infanticide … Joseph Birdsell believed that infanticide rates in prehistoric times were between 15% and 50% of the total number of births,[10] while Laila Williamson estimated a lower rate ranging from 15% to 20%.[6]:66 Comparative anthropologists have calculated that 50% of female newborn babies were killed by their parents during the Paleolithic era.[12] Decapitated skeletons of hominid children have been found with evidence of cannibalism.[13]

400px-Magliabchanopage_73r“Three thousand bones of young children, with evidence of sacrificial rituals, have been found in Sardinia. Pelasgians offered a sacrifice of every tenth child during difficult times. Syrians sacrificed children to Jupiter and Juno. Many remains of children have been found in Gezer excavations with signs of sacrifice. Child skeletons with the marks of sacrifice have been found also in Egypt dating 950-720 BCE. In Carthage “[child] sacrifice in the ancient world reached its infamous zenith.”[11]:324  …

“According to Shelby Brown, Carthaginians, descendants of the Phoenicians, sacrificed infants to their gods.[25] Charred bones of hundreds of infants have been found in Carthaginian archaeological sites. One such area harbored as many as 20,000 burial urns.[25]

Picture 4Plutarch (c. 46–120 AD) mentions the practice, as do Tertullian, Orosius, Diodorus Siculus and Philo. The Hebrew Bible also mentions what appears to be child sacrifice practiced at a place called the Tophet (from the Hebrew taph or toph, to burn) by the Canaanites. Writing in the 3rd century BCE, Kleitarchos, one of the historians of Alexander the Great, described that the infants rolled into the flaming pit. Diodorus Siculus wrote that babies were roasted to death inside the burning pit of the god Baal Hamon, a bronze statue.

“… the exposure of newborns was widely practiced in ancient Greece, it was even advocated by Aristotle in the case of congenital deformity — “As to the exposure of children, let there be a law that no deformed child shall live.”[30]

“The practice was prevalent in ancient Rome, as well. … A letter from a Roman citizen to his sister, or a pregnant wife from her husband,[35] dating from 1 BC, demonstrates the casual nature with which infanticide was often viewed:

“I am still in Alexandria. … I beg and plead with you to take care of our little child, and as soon as we receive wages, I will send them to you. In the meantime, if (good fortune to you!) you give birth, if it is a boy, let it live; if it is a girl, expose it.” [36][37]

CgxAZrOUYAEeANF“In some periods of Roman history it was traditional for a newborn to be brought to the pater familias, the family patriarch, who would then decide whether the child was to be kept and raised, or left to die by exposure.[39] The Twelve Tables of Roman law obliged him to put to death a child that was visibly deformed. …

“According to William L. Langer, exposure in the Middle Ages “was practiced on gigantic scale with absolute impunity, noticed by writers with most frigid indifference”.[47]:355–356 At the end of the 12th century, notes Richard Trexler, Roman women threw their newborns into the Tiber river in daylight.[48]” …

400px-Kodeks_tudela_21“Philosopher Han Fei Tzu, a member of the ruling aristocracy of the 3rd century BC, who developed a school of law, wrote: “As to children, a father and mother when they produce a boy congratulate one another, but when they produce a girl they put it to death.”[63]

“Buddhist belief in transmigration allowed poor residents of the country to kill their newborn children if they felt unable to care for them, hoping that they would be reborn in better circumstances. Furthermore, some Chinese did not consider newborn children fully “human”, and saw “life” beginning at some point after the sixth month after birth.[65]

“Contemporary writers from the Song dynasty note that, in Hubei and Fujian provinces, residents would only keep three sons and two daughters (among poor farmers, two sons and one daughter), and kill all babies beyond that number at birth.[66]”

“It was not uncommon that parents threw a child to the sharks in the Ganges River as a sacrificial offering. The British colonists were unable to outlaw the custom until the beginnings of the 19th century.[82]:78

“According to social activists, female infanticide has remained a problem in India into the 21st century, with both NGOs and the government conducting awareness campaigns to combat it.[83] …

“In the Eastern Shoshone there was a scarcity of Indian women as a result of female infanticide.[100] For the Maidu Native Americans twins were so dangerous that they not only killed them, but the mother as well.[101] In the region known today as southern Texas, the Mariame Indians practiced infanticide of females on a large scale. Wives had to be obtained from neighboring groups.[102]

Meanwhile in the Americas:

In 2005 a mass grave of one- to two-year-old sacrificed children was found in the Maya region of Comalcalco. The sacrifices were apparently performed for consecration purposes when building temples at the Comalcalco acropolis.[2] …

Archaeologists have found the remains of 42 children sacrificed to Tlaloc (and a few to Ehecátl Quetzalcóatl) in the offerings of the Great Pyramid of Tenochtitlan. In every case, the 42 children, mostly males aged around six, were suffering from serious cavities, abscesses or bone infections that would have been painful enough to make them cry continually. Tlaloc required the tears of the young so their tears would wet the earth. As a result, if children did not cry, the priests would sometimes tear off the children’s nails before the ritual sacrifice.[7]

And don’t get me started on cannibalism.

It is perhaps more profitable to ask which cultures didn’t practice some form of infanticide/infant sacrifice/cannibalism than which ones did. The major cases Wikipedia notes are Ancient Egypt, Judaism, Christianity, and Islam (we may note that Judaism in many ways derived from ancient Egypt, and Christianity and Islam from Judaism.) Ancient Egypt stands out as unique among major the pre-modern, pre-monotheistic societies to show no signs of regular infanticide–and even in the most infamous case where the Egyptian pharaoh went so far as to order the shocking act, we find direct disobedience in his own household:

3 And when she [Jochebed] could not longer hide him [the baby], she took for him an ark of bulrushes, and daubed it with slime and with pitch, and put the child therein; and she laid it in the flags by the river’s brink.4 And his sister stood afar off, to wit what would be done to him.

pharaohs_daughter-15 And the daughter of Pharaoh came down to wash herself at the river; and her maidens walked along by the river’s side; and when she saw the ark among the flags, she sent her maid to fetch it.

6 And when she had opened it, she saw the child: and, behold, the babe wept. And she had compassion on him, and said, “This is one of the Hebrews’ children.”

7 Then said his sister to Pharaoh’s daughter, “Shall I go and call to thee a nurse of the Hebrew women, that she may nurse the child for thee?”

8 And Pharaoh’s daughter said to her, “Go.” And the maid went and called the child’s mother.

9 And Pharaoh’s daughter said unto her, “Take this child away, and nurse it for me, and I will give thee thy wages.” And the women took the child, and nursed it.

10 And the child grew, and she brought him unto Pharaoh’s daughter, and he became her son. And she called his name Moses: and she said, “Because I drew him out of the water.”

–Exodus 2:3-10

I don’t know the actual infanticide numbers in modern Muslim countries (le wik notes that poverty in places like Pakistan still drives infanticide) but it is officially forbidden by Islam.

According to Abortions in America: • Black women are five times more likely to abort than white women. • 69% of pregnancies among Blacks are unintended, while that number is 54% among Hispanics and 40% of pregnancies among Whites. • Planned Parenthood, ... has located 80% of its abortion clinics in minority neighborhoods

Today, between the spread of Abrahamic religions, Western Values, and general prosperity, the infanticide rate has been cut and human sacrifice and cannibalism have been all but eliminated. Abortion, though, is legal–if highly controversial–throughout the West and Israel.

According to the CDC, the abortion rate for 2013 was 200 abortions per 1,000 live births, or about 15% of pregnancies. (The CDC also notes that the abortion rate has been falling since at least 2004.) Of these, “91.6% of abortions were performed at ≤13 weeks’ gestation; … In 2013, 22.2% of all abortions were early medical abortions.”

To what can we attribute this anti-infanticide sentiment of modern monotheistic societies? Is it just a cultural accident, a result of inheritance from ancient Egypt, or perhaps the lucky effects of some random early theologian? Or as the religious would suggest, due to God’s divine decree? Or is it an effect of the efforts parents must expend on their few children in societies where children must attend years of school in order to succeed?

According to Wikipedia:

In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus upon either increased quantity of offspring at the expense of individual parental investment of r-strategists, or reduced quantity of offspring with a corresponding increased parental investment of K-strategists, varies widely, seemingly to promote success in particular environments. …

In r/K selection theory, selective pressures are hypothesised to drive evolution in one of two generalized directions: r– or K-selection.[1] These terms, r and K, are drawn from standard ecological algebra as illustrated in the simplified Verhulst model of population dynamics:[7]

d N d t = r N ( 1 − N K ) {\frac {dN}{dt}}=rN\left(1-{\frac {N}{K}}\right)

where r is the maximum growth rate of the population (N), K is the carrying capacity of its local environmental setting, and the notation dN/dt stands for the derivative of N with respect to t (time). Thus, the equation relates the rate of change of the population N to the current population size and expresses the effect of the two parameters. …

As the name implies, r-selected species are those that place an emphasis on a high growth rate, and, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K).[8] A typical r species is the dandelion Taraxacum genus.

In unstable or unpredictable environments, r-selection predominates due to the ability to reproduce quickly. There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely. …

By contrast, K-selected species display traits associated with living at densities close to carrying capacity, and typically are strong competitors in such crowded niches that invest more heavily in fewer offspring, each of which has a relatively high probability of surviving to adulthood (i.e., low r, high K). In scientific literature, r-selected species are occasionally referred to as “opportunistic” whereas K-selected species are described as “equilibrium”.[8]

In stable or predictable environments, K-selection predominates as the ability to compete successfully for limited resources is crucial and populations of K-selected organisms typically are very constant in number and close to the maximum that the environment can bear (unlike r-selected populations, where population sizes can change much more rapidly).

Traits that are thought to be characteristic of K-selection include large body size, long life expectancy, and the production of fewer offspring, which often require extensive parental care until they mature.

Of course you are probably already aware of Rushton’s R/K theory of human cultures:

Rushton’s book Race, Evolution, and Behavior (1995) uses r/K selection theory to explain how East Asians consistently average high, blacks low, and whites in the middle on an evolutionary scale of characteristics indicative of nurturing behavior. He first published this theory in 1984. Rushton argues that East Asians and their descendants average a larger brain size, greater intelligence, more sexual restraint, slower rates of maturation, and greater law abidingness and social organization than do Europeans and their descendants, who average higher scores on these dimensions than Africans and their descendants. He theorizes that r/K selection theory explains these differences.

I’d be remiss if I didn’t also mention that the article states, “Rushton’s application of r/K selection theory to explain differences among racial groups has been widely criticised. One of his many critics is the evolutionary biologist Joseph L. Graves, who has done extensive testing of the r/K selection theory with species of Drosophila flies. …”

Genetics or culture, in dense human societies, people must devote a great deal of energy to a small number of children they can successfully raise, leading to the notion that parents are morally required to put this effort into their children. But this system is at odds with the fact that without some form of intervention, the average married couple will produce far more than two offspring.

Ultimately, I don’t have answers, only theories.

Entropy, Life, and Welfare (pt 1)

340px-dna_structurekeylabelled-pn_nobb

(This is Part 1. Part 2 and Part 3 are here.)

All living things are basically just homeostatic entropy reduction machines. The most basic cell, floating in the ocean, uses energy from sunlight to order its individual molecules, creating, repairing, and building copies of itself, which continue the cycle. As Jeremy England of MIT demonstrates:

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England … has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. …

This class of systems includes all living things. England then determined how such systems tend to evolve over time as they increase their irreversibility. “We can show very simply from the formula that the more likely evolutionary outcomes are going to be the ones that absorbed and dissipated more energy from the environment’s external drives on the way to getting there,” he said. …

“This means clumps of atoms surrounded by a bath at some temperature, like the atmosphere or the ocean, should tend over time to arrange themselves to resonate better and better with the sources of mechanical, electromagnetic or chemical work in their environments,” England explained.

Self-replication (or reproduction, in biological terms), the process that drives the evolution of life on Earth, is one such mechanism by which a system might dissipate an increasing amount of energy over time. As England put it, “A great way of dissipating more is to make more copies of yourself.” In a September paper in the Journal of Chemical Physics, he reported the theoretical minimum amount of dissipation that can occur during the self-replication of RNA molecules and bacterial cells, and showed that it is very close to the actual amounts these systems dissipate when replicating.

usenergy2009Energy isn’t just important to plants, animals, and mitochondria. Everything from molecules to sand dunes, cities and even countries absorb and dissipate energy. And like living things, cities and countries use energy to grow, construct buildings, roads, water systems, and even sewers to dispose of waste. Just as finding food and not being eaten are an animal’s first priority, so are energy policy and not being conquered are vital to a nation’s well-being.

Hunter-gatherer societies are, in most environments, the most energy-efficient–hunter gatherers expend relatively little energy to obtain food and build almost no infrastructure, resulting in a fair amount of time left over for leisure activities like singing, dancing, and visiting with friends.

But as the number of people in a group increases, hunter-gathering cannot scale. Putting in more hours hunting or gathering can only increase the food supply so much before you simply run out.

energyvsorganizationHorticulture and animal herding require more energy inputs–hoeing the soil, planting, harvesting, building fences, managing large animals–but create enough food output to support more people per square mile than hunter-gathering.

Agriculture requires still more energy, and modern industrial agriculture more energy still, but support billions of people. Agricultural societies produced history’s first cities–civilizations–and (as far as I know) its first major collapses. Where the land is over-fished, over-farmed, or otherwise over-extracted, it stops producing and complex systems dependent on that production collapse.

I’ve made a graph to illustrate the relationship between energy input (work put into food production) and energy output (food, which of course translates into more people.) Note how changes in energy sources have driven our major “revolutions”–the first, not in the graph, was the taming and use of fire to cook our food, releasing more nutrients than mere chewing ever could. Switching from jaw power to fire power unlocked the calories necessary to fund the jump in brain size that differentiates humans from our primate cousins, chimps and gorillas.

That said, hunter gatherers (and horticulturalists) still rely primarily on their own power–foot power–to obtain their food.

Scheme of the Roman Hierapolis sawmill, the earliest known machine to incorporate a crank and connecting rod mechanism. Note the use of falling water to perform the work, rather than human muscles.

The Agricultural Revolution harnessed the power of animals–mainly horses and oxen–to drag plows and grind grain. The Industrial Revolution created engines and machines that released the power of falling water, wind, steam, coal, and oil, replacing draft animals with grist mills, tractors, combines, and trains.

Modern industrial societies have achieved their amazing energy outputs–allowing us to put a man on the moon and light up highways at night–via a massive infusion of energy, principally fossil fuels, vital to the production of synthetic fertilizers:

Nitrogen fertilizers are made from ammonia (NH3), which is sometimes injected into the ground directly. The ammonia is produced by the Haber-Bosch process.[5] In this energy-intensive process, natural gas (CH4) supplies the hydrogen, and the nitrogen (N2) is derived from the air. …

Deposits of sodium nitrate (NaNO3) (Chilean saltpeter) are also found in the Atacama desert in Chile and was one of the original (1830) nitrogen-rich fertilizers used.[12] It is still mined for fertilizer.[13]

Actual mountain of corn
Actual mountain of corn, because industrial agriculture is just that awesome

Other fertilizers are made of stone, mined from the earth, shipped, and spread on fields, all courtesy of modern industrial equipment, run on gasoline.

Without the constant application of fertilizer, we wouldn’t have these amazing crop yields:

In 2014, average yield in the United States was 171 bushels per acre. (And the world record is an astonishing 503 bushels, set by a farmer in Valdosta, Ga.) Each bushel weighs 56 pounds and each pound of corn yields about 1,566 calories. That means corn averages roughly 15 million calories per acre. (Again, I’m talking about field corn, a.k.a. dent corn, which is dried before processing. Sweet corn and popcorn are different varieties, grown for much more limited uses, and have lower yields.)

per-capita-world-energy-by-sourceAs anyone who has grown corn will tell you, corn is a nutrient hog; all of those calories aren’t free. Corn must be heavily fertilized or the soil will run out and your farm will be worthless.

We currently have enough energy sources that the specific source–fossil fuels, hydroelectric, wind, solar, even animal–is not particularly important, at least for this discussion. Much more important is how society uses and distributes its resources. For, like all living things, a society that misuses its resources will collapse.

To be continued…Go on to Part 2 and Part 3.

 

Graph of energy input vs. output by economic type.

energyvsorganizationI have been looking for this graph for some time, failed, and finally re-created it from memory. So warning: this was re-created from memory. A really old memory.

Anyway, this graph shows the relationship between energy inputs (work) and energy output (typically food, but also shelter, children, luxury goods, etc.) for a given variety of human technology/economic organizational structure.

(Note that the graph is not to scale and only a conceptual representation of the idea.)

So for example, in a hunter gathering society, inputing more energy by hunting more often will reward people with more food, but only up to a point. As game becomes scarcer, hunters bring home less food, and eventually you eat all of the animals in the area and are actually getting less out of hunting than you’re putting into it.

Even at its maximum efficiency, a hunter-gatherer society simply can’t (in most environments) obtain much food and can’t support many people.

Growing food takes much more energy, but the results support far more people.

Modern industrial societies take a ton of energy to run, but also support billions of people, cities, etc.

Of course, even modern industrial societies still need to be careful about that right-hand side of the curve.
