Migration was inferred from the Tibetan to the Han sample, with recent admixture in the opposite direction.<\/p>\n<\/blockquote>\n<p>2,750 years would place the divergence of modern Tibetans and Chinese a few hundred years before Confucius. In fact, it would technically post-date the first historically attested Chinese writing, from the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Shang_Dynasty\">Shang dynasty<\/a>.

There are many ways you can explain this sort of divergence time, but one way which I elucidated below is rather simple.
