Figure 5.9 First entry of Y-chromosome lines into Central Asia. As with mtDNA (Figure 5.7), the entry routes correspond with major Asian rivers. Seth’s grandsons Polo and TAT entered to the west of the Himalayas, dominating North Asia. The rest of East Asian Y lines entered from the Indo-Pacific coast, with Ho dominating China and Southeast Asia, and Cain further north.

We have seen how the early beachcombers could have split successively at various points on their journey round the Indo-Pacific coast and how, by 40,000 years ago, they had colonized most of Asia and the Antipodes. The first inland branch going north from India gave rise to the Upper Palaeolithic hunters of the Central Asian Steppe; later branches forging up the great rivers of Southeast Asia ultimately gave rise to a populations we now call Mongoloid. Evidence for so-called Mongoloid types, however, did not appear in Asia until the time of the last glacial maximum, around 20,000 years ago. So the forces that produced this physical divergence may have continued to build up for a long time after the first Asians arrived in North Asia. This leads us on to the next climatic phase of our story – the Great Freeze.
