Too early to settle the Aryan migration debate

With genetic data currently available, it is difficult to deduce the direction of migration either into India or out of India during the Bronze Age

On June 17, The Hindu published an article by Tony Joseph (“How genetics is settling the Aryan migration debate”) on current genetic research in India and stated that “scientists are converging” on the Aryan migration to the Subcontinent around 2000-1500 BC. This conclusion was mainly based on the results obtained from the paternally inherited markers (Y chromosome), published on March 23, 2017 in a scientific journal, BMC Evolutionary Biology, by a team of 16 co-authors including Martin P. Richards of the University of Huddersfield, which compiled and analysed Y chromosome data mainly from the targeted South Asian populations living in the U.K. and U.S. However, anyone who understands the complexity of Indian population will appreciate that Indians living outside the Subcontinent do not reflect the full diversity of India, as the majority of them are from caste populations with limited subset of regions.
