Barley cultivation was developed in the Indus Valley. - Stephen Oppenheimer

We find the highest rates and greatest diversity of the M17 line in Pakistan, India, and eastern Iran, and low rates in the Caucasus. M17 is not only more diverse in South Asia than in Central Asia, but diversity characterizes its presence in isolated tribal groups in the South, thus undermining any theory of M17 as a marker of a “male Aryan invasion” of India. One average estimate for the origin of this line in India is as much as 51,000 years. All this suggests that M17 could have found his way initially from India or Pakistan, through Kashmir, then via Central Asia and Russia, before finally coming into Europe. (Oppenheimer, 2003: 152)

First, that the Europeans’ genetic homeland was originally in South Asia in the Pakistan/Gulf region over 50,000 years ago; and second, that the Europeans’ ancestors followed at least two widely separated routes to arrive, ultimately, in the same cold but rich garden. The earliest of these routes was the Fertile Crescent. The second early route from South Asia to Europe may have been up the Indus into Kashmir and on to Central Asia, where perhaps more than 40,000 years ago hunters first started bringing down game as large as mammoths.

Another geneticist, S. Oppenheimer, offers independent confirmation (2003) that there was no Aryan entry, either male or female; he focuses on the M17, or so-called “Caucasoid” (=Aryan!), genetic marker: “South Asia is logically the ultimate origin of M17 and his ancestors; and sure enough we find highest rates and greatest diversity of the M17 line in Pakistan, India and eastern Iran, and low rates in the Caucasus. M17 is not only more diverse in South Asia than in Central Asia but diversity characterizes its presence in isolated tribal groups in the south, thus undermining any theory of M17 as a marker of a ‘male Aryan invasion’ of India” .
