Abstract

Ancient DNA isolation from the tropical countries has been shown to be very difficult in the past. Here for the first time we have been successful in isolating ancient DNA from Indian cattle samples. We were able to obtain DNA and sequence the partial mitochondrial D-loop in 3 of the 15 bovine fossil samples ranging in age from 2000 BC to 1000 AD, and were able to further identify the most recent sample as being of Bos indicus origin. Our results on ancient DNA extraction from India will encourage other researchers in this field to carry out further studies of ancient DNA from Indian bovine samples. Our results represent the first successful extraction and amplification of bovine ancient DNA from India, and thus may pave the road for a better understanding of demographic and historical processes of cattle domestication that has taken place in this region.
