We know Tibet was well populated long before the neolithic, with times of expansion when climate allowed. Surely, much of Tibet's autosomal DNA goes back much further than the neolithic.<br /><br />I agree with the importance of the <i>valleys of the Hengduan Mountain range</i> - in the sense that they were the/a channel for the population of East and Northeast Asia ~50,000 ya - but from west to east.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.com
