A new study released in 2013 by Kanzawa-Kiriyama Hideaki shows that the Jomon population are genetically closer to Papuans and Melanesians, populations located in Oceania. The author also demonstrated that the Jomon have significant Denisovan admixture, which is also found among Papuans, Melanesians and some Negrito ethnic groups in the Philippines.
The study suggests that the Ainu and Ryukyuan populations of Japan retained much of their Jomon ancestry, however the Ainu received gene flow from neighboring populations such as Nivkhs and the Ryukyuans received genetic input from the Yayoi. In the principal component analysis, the Jomon were genetically close to Cambodians and were genetically more similar to Melanesians and Papuans when compared to other East Eurasians. Therefore the Japanese people may have significant amounts of Melanesian-like or Papuan-like ancestry in their genomes.
If the Jomon are part Denisovan, the Denisovan mix may have gone in quite early before 13,000 YBP. It went ~16,000 YBP or before when the proto-Jomon were living in Thailand. At this time, Denisovan mix also went into Papuans and Melanesians. So there was Denisovan mixing with ancient Australoid proto-Asians long ago, 15,000 YBP or earlier, somewhere in the Wallacea – Southeast Asian region.
I keep telling you guys this but none of you believe me. I have heard that the skulls are Australoid too, but I would have to look that up. Kennewick Man in the US, a Paleoindian, looks more like a Polynesian or an Ainu than any other living race. Polynesians are 1/2 Melanesian.
The Jomon are linked by skulls to skulls from Thailand 16,000 YBP. So the proto-Jomon lived in Thailand 16,000 YBP, and they must have gotten on boats and gone to Japan eventually, maybe by 13,000 YBP, where they formed the Ryukuyans and the Ainu. And what did the Jomon look like 16,000 YBP? Skulls from Thailand 25,000 YBP look like Aborigines.
There is some interesting evidence that some of the very earliest settlers to the Philippines, ~15,000 YBP, may have been Ainu-like from the way they are described. There is also good evidence that the Jomon people may have been a significant input to the Aborigines. The modern Aborigines are a mix between Atlanteans, who came 15-20,000 YBP and seem to be Ainuids, maybe from the Thailand Jomon, and Carpinterians, possibly from southeastern India from 10-15,000 YBP. 13,000 YBP, Southeastern Indians looked like Aborigines.
The Carpinterian-Atlantean mix was complete in Australia by maybe 12,000 YBP and the Aborigines were created. Prior to 17,000 YBP, the Aborigines seem to have looked very different. There are very early skulls from Australia before 20,000 YBP that are extremely robust and almost look like Homo Erectus.
So you can see that from a period of 13-25,000 YBP, people who looked like Aborigines were widespread across Asia from southeastern India to Thailand to Australia to the Philippines to Japan.
It is looking more and more like the proto-Asians or the pre-Mongoloid Asians were some sort of Australoid type. Evolution in Asia then went Australoid -> Mongoloid although it was not completed in certain places such as Melanesia, New Guinea, Australia and South India.
