Substantial progress on how modern humans settled and adapted to the Tibetan Plateau has been achieved in the past few years. In particular, genetic evidence suggests that peopling the Plateau was attributed mainly to the neolithic immigration initiated from northern China ~7 kilo years ago (kya). Furthermore, a very small proportion of genetic components showed a restricted distribution in the Tibetans and were estimated to be extraordinarily ancient, thus plausibly reflecting an early dispersal event onto the Plateau during the Late Pleistocene. This observation is in good agreement with the previous archeological records. Recently, a more extensive study, by analyzing archeological materials collected from 53 Neolithic and Bronze sites in northeast Tibetan Plateau, provides solid evidence in support of the Neolithic immigration into Tibet and, furthermore, suggests a permanent settlement on the high areas of the Plateau likely occurred till 3.6 kya. Although some inconsistency on dating the entrance exists between archeological and genetic studies, likely introduced by the methodology in time estimation, evidence from both disciplines supports the notion that the Tibetans can trace their origin to the Neolithic dispersal from northern China.
