Kennewick Man, Ainus and Sunda


Two men were walking along the bank of the Columbia River in Washington, U.S. on July 28, 1996 when they came across a human skull, they quickly notified the autorities who inspected the area and, after a thorough search, managed to recover an almost complete skeleton, belonging to a man. This is how the "Kennewick Man" remains were discovered.


An initial inspection by an archaeologist [3] concluded that the man was not a Native American because the skull had a "caucasoid" appearance. A bone sample was sent to a laboratory and dated. We now know that these remains are between 8,000 and 9,500 years old. Which, by American standards is very ancient.


An act of Congress, The Native American Graves Protection and Repatriation Act (NAGPRA) was passed in 1990 with the goal of redressing the evils of the past, when Native American graves were profanated and their bones stolen and placed in Museums. The good intentions behind this legislation (which sought to return these remains to their original resting places in their tribal communities), has been distorted by the very extreme view held by some Native groups which are against any studies conducted on Paleo-Indian remains.


Actually most "modern" Native communities are relativley recent arrivals to their traditional tribal territories none go back more than one or two thousand years at most. Yet, they will go to court and in most cases succeed to get remains that date back thousands of years returned to "their homeland". In many cases the only link between the Paleoindians and the modern natives is the land where the remains were found.


Kennewick man was no exception, in 1996 some native groups took a hard stand and went to court to stop any further studies on his remains. Native American groups and the Federal Government of the U.S. combined their resources against the scientists who wanted to learn as much as possible from these extremely valuable ancient remains.


The legal battle took 8 years. In 1998 Kennewick man's bones were sent to the Burke Museum (Washington state) to protect them until the lawsuit was settled. They are still safeguarded at the Museum. [1]


The case was heard by a U.S. District Court which found that the remains could not be classified as "Native American". His ruling was appealed and the 9th Circuit Court of Appeals upheld that decision in 2004. So the remains, which were found on Federal land, are now in custody of the U.S. Army Corps of Engineers and will remain so indefintely unless the Natives can somehwo prove in the future that Kennewick was a Native American. [1]


What have we learnt from the remains?


The remains comprise an almost complete skeleton (only some bones from hands and feet and the sternum are missing) which belonged to a tall man (about 1.73 m - 5.67 ft.) between 40 and 55 years old.


Although his DNA was intact, the tests were done on two samples but were inconclusive! (more on this below).


He had the broken off remains of a flint leaf-shaped serrated projectile stuck in his right ilium (hip bone). The wound was partly healed and the stone spear tip was quite large: 20 x 54 mm (0.78 x 2.12 in), [2] however, "The extensive amount of bone that has grown around the stone point suggests that the point was in place for a considerable amount of time and was not the cause of death." [3]


The surprising part is the skull, the cranial index marks it as dolichocephalic (long and narrow skull) instead of bracycephalic (short and wide skull) as found among the modern Natives. His face was narrow instead of broad and had a pronounced chin. This and other features gave him a "caucasoid" appearance. Yet, surprisingly his teeth were Sundadont like those found among South Asians. [2]


A clay facial reconstruction gives him a very "Caucasian" look indeed, [6] below is another view of this Kennewick man's face: [7]

Sundadonty is not a Caucasian trait, it is part of the "Mongoloid dental complex" [4], which evolved locally in Sunda Land (insular Indonesia); very similar teeth are found among Aboriginal Australians which "are also generally like those of Jomonese and some Ainus, suggesting that members of the late Pleistocene Sundaland population could have initially colonized Sahulland as well as the continental shelf of East Asia northward to Hokkaido" [4].

East Asians to the north of Sunda (i.e. Chinese, Japanese, Koreans, Mongolians) all have Sinodonty (dental shoveling). In general people belonging to Mongoloid groups (North Eastern Asians and, also American Indians) have the highest frequency of shoveled incisors while the rest of the world has chiseled ones. Shoveling is caused by the Ectodysplasin receptor gene (EDAR), also associated with hair thickness and the size and quantity of sweat and mammary glands. It is frequent in Asian populations and absent in Europeans, Africans, Denisovans and the Mal'ta remains from Siberia who carry the ancestral allele. The mutation or introgression (admixed through direct contact with H. erectus) is believed to have appeared in central China >30 Kya, a late date in my opinion since it was obtained by simulations restrained by a 15 Kya date for peopling America, which is far to recent. [5]


His teeth


The sundadonty of Kennewick man is an interesting find because it links him to Sunda (Insular Southeast Asia) and the archaic population of Japan, the Ainus.


The map above shows a discontinuity in the Sundadont range (blue). It is the intromission of Sinodonty (yellow) which cuts off Sunda in the south from Taiwan, Hokkaido, the Kuril Islands, Sakhalin and the tip of Kamchatka in the north.


This gap is currently occupied by sinodont populations (Chinese, Koreans and Japanese).


A simpe explanation for this discontinual distribution is that the sundadonts were the original people inhabiting the coastal areas of Oriental Asia and were later overlain or displaced to their current insular ranges by sinodonts in the central region (China, Korea, Japan).


Another option is that the Sundadonts moved from Sunda northwards, along the coastal areas in boats, or walked along the now submerged continental shelf alll the way to Hokkaido -the current Ainu territory (yet they seem to have failed occupying the main southern Japanese islands, or were later displaced from there by sinodonts).

Did a branch of these migratory sundadonts reach America before the sindonts whose dental pattern now prevails among Amerindians? or, since sinodonty is a Homo erectus trait, did the admixture leading to Amerindian sinodonty take place in America, between an early arrived sundadont H. sapiens population and the ancient H. erectus settlers in America?


Turner [8] proposes a theory where "Sundadonty or more likely proto-Sundadonty, [is] the ancestral pattern for all modern humans". He bases this on the "generalized" appearance of Southeast Asian population: "they possess various external physical features of many geographic races, although usually in relatively low frequency". Interestingly "when South Siberian teeth are compared with those of Sundadonts, they show remarkable similarities. Because South Siberian [...] hybrid condition retrodicts the probable dental pattern of the common ancestors of Europeans and Asians before these derived groups drifted to their distinctive patterns by late Pleistocene times..." [8].


So Sunda would be the source of this dental morphology, coinciding with the place from which Y chromosome Haplogroup C radiated into New Guinea, Australia, India, China and Northeast Asia. see my post on haplogroup C. South Siberians also have hg. C at low frequencies.


The Ainu


Regarding the Ainu people of northern Japan, their similarity to Sunda populations such as the Bataks of Sumatra and the Dayaks of Borneo (shee photos below) was reported back in 1872 [9]. More recently, Genetic studies link the Ainu to Amerindians, and one should reread those studies within the hypothesis mentioned above. Perhaps both groups (Amerindians and Ainu) share a common sundadont ancestor which is the main reason for the similarities detected in these genetic studies.

The impression I get is that they are two different kinds of Ainu.

His DNA


The DNA samples taken from the Kennewick man did not give any conclusive results. The tests were botched (since I don't believe in conspiracy theories, I can only guess that they were done in an inadequate manner or that the technology used was rudimentary, perhaps the samples were unwittingly contaminated, etc.). Below is the conclusions by the National Parks Service [3]:


"Thus, two separate amplifications from two different extractions suggested that Kennewick Man does not belong to haplogroup D (because the fragment was at least partially digested at np 5176 by Alu I restriction enzyme) while a single amplification from one of the two extractions suggests he might belong to haplogroup D. Given that at this point it was still unclear whether or not either of the two extractions were clean (i.e., uncontaminated), amplifications from the extracts had given conflicting information and neither extract had been successfully tested for the diagnostic markers for haplogroups B, C or X, it was impossible to determine to which, if any, of the common modern American Indian mtDNA haplogroups the Kennewick remains belong. At very most, our results provided, at this point, no evidence that the Kennewick remains belonged to haplogroups A, B or C [3]


In other words he does not belong to mtDNA haplogroups A, B or C. And the two tests gave differing results for hg. D (one was positive, the other negative). So he may or may not belong to haplogroup D. He may belong to X or M or any of the other haplogroups for which he was not tested.


I have not found any records regarding his Y chromosome analysis.


Closing Comments


Despite the theories put forth by some blogs and forums regarding a European origin for Kennewick man and the links they try to build between him and the Solutreans and Cro-Magnons of Europe, I am inclined towards an Asian origin for the Kennewick man


His sundadont teeth clearly set him apart from any modern Europeans. He is closer to the more ancient modern human migrants that reached Sunda, Sahul and what is now insular Eastern Asia in the Out of Africa initial migration some 70 kya. He probably represents this basic and most archaic line of modern humans who may have reached America not long after their departure from Africa. They do not, in my opinion, represent the more recent "white Europeans" as some propose (many of these forums have some white supremacist viewpoints, which I abhor).


A clear typing of his mtDNA and Y chromosomes will settle the issue of this man and lead us to ask interesting questions regarding why are there no contemporary Caucasoid-looking Native Americans? and maybe clarify what is the exact link between these Sundadont populations, perhaps some other gene similar to the EDAR of the sinodonts?


I will dig deeper into the Ainu, they intrigue me and I want to learn more about them.

  1. The very appearence of the mongoloid phenotype is a mystery. From australoid to mongoloid is one big change, yet they are related in their genes, which is atested by the dental patterns - strongly influenced by genetics. I strongly believe that caucasoid phenotypes in the Americas are caused by retention of more australoid features. Europeans have put themselves as standard, but truth is that there is Mongoloid, Negroid and Australoid. Caucasians are in between, not in the extreme. Not surprisingly we tell european dentition from what it is not and not from what it is. Arrogance. :)

  2. My recollection is that the Spirit Cave Mummy from northern Nevada was speculated to have been related to Kennewick Man based on dental type, but also the blanket he was wrapped in's weaving was similar to a pattern found only in Borneo.
    One of his curators postulated early immigration by a "pan-pacific race", very closely resembling the path you suggest for Kennewick's family.
    Thanks for the wonderful site, I'll reply again when I've read everything.

  3. The Ainu connection is an interesting one I've often wondered about due to cultural similarities and the fact that the ocean currents directly link Japan to Haida Gwaii.

  5. First of all the 18th century racial theories are not valid. You can have literally two siblings and one can have what is more of the "Caucasian" trait, and the other can have less of those features. And this occurs in literally most groups all over the world.

    DNA is what is important, none of these groups are related at all to Europeans and in fact are some of the least related people to Europeans. The Ainu are Jomon, natives of Japan. Their origin is from old world Asians around 16,000+ years ago who made it into Japan during the ice age. These are not European people and less related to Europeans than Chinese people are to Europeans.
    The Ainu/Jomon are Asian in their DNA and related to north east Siberians and slightly to some northern native Americans.

    Also the Ainu specifically like other northern Asians have a large gap between their upper eyelash's and their eyebrow (creating a large gap in between).

    If you fill in this area with fat, they would have Asian looking eyes. They have a rather Asian structure (but just more sunk in).

    Also the more advanced population to reach Japan via boats around 3500 years ago were the Yayoi, which were a little taller and looked somewhat like a Korean, but with possible a narrower face which the old skulls show.

    The Jomon existed all throughout Japan (remember the Ainu are just one of the Jomon people). The Yayoi came in from the Korean peninsula so they landed first on Honshu.

    There were hairy Jomon people all over Honshu, one was the Emishi and there were many others as well. The Yayoi interbred with them.

    All Japanese people are part Yayoi and part Jomon. So the Japanese people shouldn't be talked about as if they have nothing to do with Jomon, which is all too common from your average internet idiot who doesn't know what they are talking about.

    Mainland Japanese are around on average 19% Jomon in DNA, the rest being from the Yayoi. The Ainu also are Japanese people, as are the Ryukyu Japanese who have a bit more Jomon DNA than mainland Honshu people.

    Virtually all people in Hokkaido have some Yayoi DNA also today (in fact many in Hokkaido are just like Honshu people today in their mix ratio), Japanese people are all mixed with these two groups, just to varying degrees.


    I make this comment as it's annoying to Japanese people when some western kids first find out about groups like the Jomon/Ainu and start referring to them as not being Japanese and then referring to Japanese people as if they are the original Yayoi. This is so ignorant.

    The Mongoloid people are no mystery, they are merely the same as proto-mongoloid skulls that just became a little finer in features and had a layer of fat fill out their eye socket more.

    They did not evolve from Australoid people either, nor is there DNA relation. Australoid people came out of Africa along southern Asia and into Australia. Australian Aboriginals are Australoids, so are Papua New Guinea people.

    East Asians arise from a different branch of people, Europeans and Asian people have a common ancestor some 45,000 years ago. East Asian DNA and European DNA is based off that, but both changed a lot and bred in with some existing hominid in their region as the migrated.


    BTW there has been more recent DNA testing on Kennewick man which determined that he is indeed highly related to native American people, and not European people.

    No scientists ever seriously claimed Kennewick man was a European in origin, the kid who found him said that and then some white nationalist sites picked it up. The fact is that the traits named "Caucasian" can exist in many different people. And they don't exist in all Europeans either, and they exist more strongly in Persian people than Europeans as well.

    You can have two siblings and one can have more of these "Caucasian" features. I would know as I am a white Australian and I have these features quite strongly, but my brother barely has them at all and his nose ridge doesn't poke out anywhere near as far as mine and he has more of a wide head and not the corners on the forehead line mine etc. I have a very strong Caucasian feature set, but my brother doesn't and we are clearly the same race though.

    This also happens in other groups of people,I have a Chinese friend and she has more Caucasian type features than her sister. I then see other Asians who have a whole combination of features, just as exists in other groups also.

    The point is, the original European people that made the racial theories were racists who wanted to deliberately choose features they liked and try to claim they are European features. And they would typically choose some pretty bad looking people from other places and claim they represent that race. Then they would call other people don't don't represent that bad example as "Caucasian looking" as in trying to take credit for it. They even used to misrepresent the Irish and claim they are subhumans and make stupid drawings of them that are totally not representative of the majority of Irish people.

    The point is that anyone who digs up these old theories (which white supremacist websites do all the time and use as a basis for their beliefs) are being very ignorant.
