River buffalo ‘first domesticated in India’

Scientists at the Central University of Kerala, Kasaragod, and the CSIR - Centre for Cellular and Molecular Biology, Hyderabad, have produced genetic evidence to establish that the river buffalo was first domesticated in India, from where it reached Mesopotamia and spread to other parts of the world.

A team comprising M. Nagarajan and Koodali Nimisha from the Central University and Satish Kumar from the CSIR centre have unravelled the domestication history of the river buffalo ( Bubalus bubalis ) by analyzing more than 400 DNA sequences representing buffalo populations in India, Pakistan, Iran, and Egypt. The domestication history of the river buffalo has been the subject of debate for many decades, mainly due to the lack of clear archaeological evidence and scientific data, though it was believed that the animal was domesticated from the Asian wild buffalo ( Bubalus arnee ), a few thousand years ago.

The scientists have now come up with evidence to prove that the river buffalo was first domesticated in the northwestern region of India, probably in the places of distribution of the present day Mehsana, Surati, and Pandharpuri breeds.

The study concludes that the domestication process involved a continuous influx of wild buffalo genes into the Indian domestic stocks after the initial domestication event.

The findings have been published in ‘Genome Biology and Evolution,’ an open access journal published by the Society for Molecular Biology and Evolution.

The domestication process has been traced back to the period prior to the mature phase of the Indus Valley civilisation (3300 BC to 1400 BC). [...] thehindu.com/
