The migration was certainly not 'coastal' in any meaningful use of the term. That would explain the 'Newar and Kathmandu harbor several deep-rooted Indian lineages'. <br /><br />"Our results revealed a predominantly East Asian-specific component in Tibet and Tamang, whereas Newar and Kathmandu are both characterized by a combination of East and South Central Asian lineages". <br /><br />Yes. The Himalayas represent a very steep cline the South and East Asian phenotype, with the cline being formed by a southward moving Mongoloid phenotype rather than a northward moving South Asian phenotype. <br /><br />"our results confirm that while the Himalayas acted as a geographic barrier for human movement from the Indian subcontinent to the Tibetan highland, it also served as a conduit for gene flow between Central and East Asia". <br /><br />Including a very ancient human movemetn east? I have long believed that Y-DNA C and mt-DNA N moved east along such a route. terrythttps://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-66879816395097829402013-06-03T23:00:11.699+03:002013-06-03T23:00:11.699+03:00IIRC, the archaeology shows the first human presen...IIRC, the archaeology shows the first human presence in Tibet at about 30 kya. Of course, new finds could alter the conclusion, but this data point ought to temper a reading of TMCRA estimates of >40 kya or >50 kya as indicating a modern human presence in Tibet that is that old.andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.com
