Papua's Neolithic was not sufficiently developed I would guess, to undergo major expansion and it was adapted to the highland niche. Still who knows? I do suspect an incipient Neolithic in the related original South Asian populations though, and this might have extended in some form to Indochina, Indonesia? The Fertile Crescent+Coastal Migration element in Southeast Asia and Malays seems too widespread there to be just noise, and maybe some more suitable soil/climate regions were occupied by this mixed Neolithic people...<br />I'll see if I can get further clues on this later.Diogeneshttps://www.blogger.com/profile/00827839380414245914noreply@blogger.comtag:blogger.com,1999:blog-6443268110928728533.post-47828612542392226602011-04-09T15:50:27.240+01:002011-04-09T15:50:27.240+01:00I had in mind, Chukchi gray.

On the same lines, I wonder if the development of agriculture in New Guinea led to some gene flow back to Indonesia and Asia.Charles Nydorfhttps://www.blogger.com/profile/16291667302870991631noreply@blogger.comtag:blogger.com,1999:blog-6443268110928728533.post-35412487207576997302011-04-07T16:58:38.512+01:002011-04-07T16:58:38.512+01:00If you're mentioning grey in Chukchi and other...If you're mentioning grey in Chukchi and other Siberians, I think it's possible since Solutrean (and Clovis) technology was particularly impressive.<br />If you're speaking of Han and related Neolithic populations further South, I think a more likely explanation is that the Chinese or East Asian Neolithic is itself a "Siberian Belt"-derived Neolithic expansion. I don't have a large amount of confidence in any of this yet, still I think it's the simplest model to explain what we're seeing.Diogeneshttps://www.blogger.com/profile/00827839380414245914noreply@blogger.comtag:blogger.com,1999:blog-6443268110928728533.post-2405370721334696832011-04-07T13:54:28.965+01:002011-04-07T13:54:28.965+01:00There is a considerable amount of American Indian ...There is a considerable amount of American Indian gray that gets into Asia. Usually this kind of thing is said to be the result of the Asian origin of American Indians but I'm wondering about another possibility: Could a demographic expansion from South and Middle America have led to the diffusion of some genes back into Asia?Charles Nydorfhttps://www.blogger.com/profile/16291667302870991631noreply@blogger.com
