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.

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.

These are a few of my favorite things (Indian DNA)

People often make the mistake of over-generalizing other people. We speak of “Indians,” “Native Americans,” or better yet, “Indigenous Peoples,” as though one couldn’t tell the difference between a Maori and an Eskimo; as though only two undifferentiated blocks of humanity existed, everywhere on the globe: noble first people who moved into the area thousands upon thousands of years ago, sat down, and never moved again, and evil invaders who showed up yesterday.

In reality, Group A has conquered and replaced Group B and been conquered and replaced in turn by Group C since time immemorial. Sometimes the conquered group gets incorporated into the new group, and years down the line we can still find their DNA in their descendants. At other times, all that’s left is an abrupt transition in the archeological record between one set of artifacts and skull types and another.

Even “Indigenous” peoples have been migrating, conquering and slaughtering each other since time immemorial. The only difference between them and Europeans is that the Europeans did it more recently and while white.

When we take a good look at the Indians’ DNA, we find evidence of multiple invasion waves, some of them genocidal. The Sururi, Pima, and Chippewyans are clearly distinct, as are the Eskimo and Aleuts:

Please note that Haak’s chart and the chart I have at the top of the blog use different colors to represent the same things; genetic admixture of course does not have any inherent color, so the choice of colors is entirely up to the person making the graph.)

The Karitiana are one of those mixed horticulturalist/hunter-gatherer tribes from deep in the Amazon Rainforest who have extremely little contact with the outside world and are suspected of having Denisovan DNA and thus being potentially descended from an ancient wave of Melanesians who either got to the Americas first, or else very mysteriously made it to the rainforest without leaving significant genetic traces elsewhere. I’m going with they got here first, because that explanation makes more sense.

The Pima People of southern Arizona had extensive trade and irrigation networks, and are believed to be descended from the Hohokam people, who lived in the same area and also built and maintained irrigation networks and cities, and are probably generally related to the Puebloan Peoples, who also built cities in the South West. An observer wrote about the Puebloans:

When these regions were first discovered it appears that the inhabitants lived in comfortable houses and cultivated the soil, as they have continued to do up to the present time. Indeed, they are now considered the best horticulturists in the country, furnishing most of the fruits and a large portion of the vegetable supplies that are to be found in the markets. They were until very lately the only people in New Mexico who cultivated the grape. They also maintain at the present time considerable herds of cattle, horses, etc. They are, in short, a remarkably sober and industrious race, conspicuous for morality and honesty, and very little given to quarrelling or dissipation … Josiah Gregg, Commerce of the Prairies: or, The journal of a Santa Fé trader, 1831–1839

Linguistically, the Pima speak an Uto-Aztecan language, connecting them with the Soshoni to the north, Hopi to the east, and the Aztecs to the south (and even further south, since the family is also spoken in Equador):

The Aztecs, as you probably already know, had a large empire with cities, roads, trade, taxes, etc.

In other words, the Pima were far more technologically advanced than the Karitiana, which suggests that the arrow of conquering here goes from Pima-related people to Karitiana-related people, rather than the other way around.

Now, obviously, the Pima did not travel down to Bolivia, kill a bunch of Karitiana people living in Bolivia, rape their women, and then head back to Arizona. More likely, the ancestors of the Karitiana once lived throughout much of South and Central America, and perhaps even further afield. The ancestors of the Pima then invaded, killing a bunch of the locals and incorporating a few of their women into their tribes. The Karitiana managed to survive in the rainforest due to the rainforest being very difficult to conquer, and the Pima failed to mix with other groups due to being the only guys interested in living in the middle of the Arizona desert.

The Chipewyan people (not to be confused with the Chippewa people, aka the Ojibwe,) live in northwest Canada and eastern Alaska, and are members of the Na-Dene Language family:

Those guys in the southern branch of the family are the Navajos and Apache. These languages are speculated to be linked to Siberian languages like the Yeniseian.

(I think the Chilote people are from Chile.)

The Algonquin people (of whom the Ojibwe are part,) come from the North East US and Canada:

There also exist a couple of languages on the California coast which appear to be related to the Algonquin Family, possibly a case of Survival on the Fringes as a new wave of invaders migrated from the Bering Strait.

The Algonquins appear to have been semi-nomadic semi-horticulturalists. They grew corn and squash and beans, and also moved around hunting game and gathering wild plants as necessary.

Where we see red admixture in Haak’s graph, that means Siberian people. Where we see dark blue + orange + teal, that’s typical European. Most likely this means that the Algonquins in Haak’s data have some recent European ancestors due to a lot of inter-marriage happening over the past few hundred years in their part of the world. (The Chipewyans live in a much more isolated part of the continent.) However, some of that DNA might also have come with them when they migrated to North America years and yeas ago, due to their ancient Siberian ancestors having merged with an off-shoot of the same groups that modern Europeans are descended from. This is a likely explanation for the Aleuts and Tlingit peoples, whose dark blue and teal patches definitely look similar to those of other Siberian peoples. (Although, interestingly, they lack the red. Maybe the red was a later addition, or just didn’t make it over there in as large quantities.)

The Eskimo I have spoken of before; they appear to have wiped out everyone else in their immediate area. They live around the coastal rim of Alaska and northern Canada.

The Aleuts likely represent some kind of merger between the Eskimo and other Siberian peoples.

 

My summary interpretation:

Wave One: The Green People. Traces of their DNA appear to be in the Ojibwe, Eskimos, and Chileans, so they may have covered most of North and South America at one time.

Wave Two: The Pink People. They wiped out the vast majority of the Green people throughout North America, but as migration thinned their numbers, they ended up intermarrying instead of killing some of the Greens down in Central and South America.

The Green People only survived in any significant numbers deep in the rainforest, where the Pink People couldn’t reach. These Greens became the Karitiana.

Wave Three: The Brown people. These guys wiped out all of the Pink people in northwest Canada and Alaska, but as migration to the east thinned their numbers, they had to inter-marry with the local Pinks. This mixed group became the Algonquins, while the unmixed Browns became the Chipewyans.

Few Browns managed to push their way south, either because they just haven’t had enough time, or because they aren’t suited to the hotter climate. Either way, most of the Pink People went unconquered to the south, allowing the Pima and their neighbors to flourish.

Wave Four: The Eskimo, who wiped out most of the other people in their area.
