And, as Dienekes points out, such a central hiatus may be exaggerated in the data because of contact/gene transfer.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-35774689786765975302010-11-26T19:01:03.777+02:002010-11-26T19:01:03.777+02:00The Luhya are among the least admixed populations ...The Luhya are among the least admixed populations in East Africa; they're almost unaltered Bantus. The ancestry of the Maasai, on the other hand, is very heterogeneous (Bantu, Nilotic, Afroasiatic).<br /><br />I also don't understand how ancient paleoanthropological finds in parts of Eurasia disprove a more recent Out of Africa scenario. There could simply have been other OOA migrations, except that their lineages did not survive.

Africa ...This is too premature to comment on this.<br /><br />Africa has more diversity and more ancestral groups. <br /><br />One of the groups may be OOA.<br /><br />All these Irulas, Mala, Madigas have high percentages of C,F,H compared to other Indian cast groups and Eurasians. This can not discount Eurasian haplo group map. CF-T. ????.<br /><br />Can we discount OOA based on this?.<br /><br />Also another interesting thing is India offers very few skeletal remains to find these traces other than live dna. India is full of stories and there are lot of stories about cross population of different species. May be Neanderthal mixture happened there and spread.South Central Haplohttps://www.blogger.com/profile/00916788636469000041noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-27168149553972677392010-11-26T04:01:55.593+02:002010-11-26T04:01:55.593+02:00"There is more and more evidence accumulating..."There is more and more evidence accumulating that there were two OOA - one of them around 120,000 years ago, and not as successful in spreading to other continents until the second one". <br /><br />Interestingly mtDNA and Y-hap evidence provide different origin dates for the two. The mtDNA fits the 120,000 year date (somewhat anyway) and the Y-hap fits better a more recent OoA. Perhaps the dates can be taken at face value in fact. That would make sense of your other comment: <br /><br />"it seems that the incredible flexibility modern humans showed after and only after ~50,000 years ago must have been caused by something tangible - be it a second OOA, or a first-time successful incorporation of local homo (Neanderthal, Heidelbergensis) contribution".terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-38723735118617434502010-11-25T14:22:39.246+02:002010-11-25T14:22:39.246+02:00The Irulas are the ones that have sometimes Africa...The <i>Irulas</i> are the ones that have sometimes African-like phenotypes, IIRC. <br /><br /><a href="http://upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Irulas1871.jpg/498px-Irulas1871.jpg" rel="nofollow"> upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Irulas1871.jpg/498px-Irulas1871.jpg </a> (the ones on the right) <br /><br />I'd like to see more studies about the Adaman islanders too (as they also have kind of African-like phenotypes).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7785493.post-18603883176792233782010-11-25T12:59:13.975+02:002010-11-25T12:59:13.975+02:00I think it makes sense.

There is more and more evidence accumulating that there were two OOA - one of them around 120,000 years ago, and not as successful in spreading to other continents until the second one. Something was still missing, to accomplish that. <br /><br />Toba clearly would have interfered --- but it would have only taken a very few thousand years to reach population saturation in India to then force further migration. We know the climate changed ~45,000 - 50,000 years ago, which helped - but something else happened shortly before to make things happen.<br /><br />To me, it seems that the incredible flexibility modern humans showed <i>after and only after</i> ~50,000 years ago must have been caused by something tangible - be it a second OOA, or a first-time successful incorporation of local homo (Neanderthal, Heidelbergensis) contribution.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.com
