To me it seems more likely that neither movement was via India, partly because there is no remnant population in India to support such a scenario. On the other hand it is very likely that any movement through anything approaching Central Asia would have been exterminated through that region periodically. <br /><br />I draw your attention to this recent paper on mt-DNA N, a haplogroup particularly diverse in Australia: <br /><br />http://www.pubfacts.com/detail/26053380/Carriers-of-Mitochondrial-DNA-Macrohaplogroup-N-Lineages-Reached-Australia-around-50000-Years-Ago-fo<br /><br />Also this one is relevant: <br /><br />https://faculty.washington.edu/wjs18/Pop_Structure/Science-2011-Rasmussen-94-8.pdf<br /><br />terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-88191267481223309602015-07-24T21:32:41.229-06:002015-07-24T21:32:41.229-06:00There is no doubt that Athabascans have Asian admi...There is no doubt that Athabascans have Asian admixture but it seems more pronounced in the paternally-inherited Y chromosomes than the maternally-inherited mtDNAs. Therefore, did they belong to families or armies? <br /><br />The small amount of Asian admixture in the southern Athabascan mtDNA sample is Aleut or Saqqaq-like. <br />G Horvathttps://www.blogger.com/profile/09821897990245113279noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-62911629073812840602015-07-24T14:09:20.478-06:002015-07-24T14:09:20.478-06:00While the Na-Dene are mainly Native American, a pr...While the Na-Dene are mainly Native American, a previous study, IIRC by Reich, found that there was a distinct new wave ca. the Bronze Age of migration that was particular to the Na-Dene.

Are you referring to what I would call admixture? <br /><br />Also, Vajda renamed his presentation "to avoid the impression that the linguistic evidence of genetic relatedness presented here can, on its own, determine exactly how peoples as geographically distant today as the Ket and Athabaskans have come to speak related languages."G Horvathttps://www.blogger.com/profile/09821897990245113279noreply@blogger.com
