Indigenous Indians: genetic studies

Here are three genetic study reports. Two reports on Indian population
genetics appeared in Nature of 24 Sept. 2009 and another on the origins of
Zebu in South Asia in Molecular Biology and Evolution, Sept. 21, 2009.
These studies throw light on the indigenous evolution of human population and zebu
cattle in ancient India.
