This excellent piece on the genetics of the Ainu shows that they are in fact very different from Japanese, Koreans, Okinawans, Chinese and in fact all other East Asians. The best explanation for this is that the Australoid Ainu are the remains of the ancient Northeast Asians before they transitioned to Mongoloids 9,000 years ago.
Lonely leaf on a long branch. Look how remarkably different the Ainu are from all other East Asians.
They are now seen as Australoids and not as Caucasians as they were erroneously thought to be for a long time. The reason they were thought to be Caucasoids is because when you cross an Australoid with a Mongoloid, you often end up with a rather Caucasoid phenotype.
An old photo of a Hokkaido Ainu man, probably from the 19th Century. Note the Caucasoid phenotype. It was this resemblance that caused people to assign them to Caucasoids, but genetic tests later disproved this. Early anthropologists said the Ainu looked like “Norwegians”.
In fact, the Ainu may be the best remnants of the ancient East Asian race which may have had its beginnings around Lake Baikal 35,000 years ago. However, we know that the Ainu are related to the Jomonese, and the Jomonese can be traced all the way back to Thailand 16,000 YBP. Around that time, it is thought that the Ainu in the form of the Murrayan people journeyed to Australia, forming one of the main components of the Aborigine people. Around this same time, they may have gone to the Philippines, for their reports that one of the very ancient Filipino groups may have had an Ainu appearance.
The Ainu are the blue triangles trailing off the right. The Okinawans are the closest to the Ainu, and even they are not that close.
Interestingly, ancient Amerindians from 9-12,000 YBP have an Australoid appearance. The skulls from 9000 YBP appear Ainuid or Polynesian and the earlier skulls line up with Negritos, Papuans and Aborigines. This implies that the ancient Northeast Asians or Siberians from around the Altai region who immigrated to North America 9-12,000 YBP may have been an Ainuid people.
