Family tree for cattle, other ruminants

Pairing a new approach to prepare ancient DNA with a new scientific technique developed specifically to genotype a cow, an MU animal scientist, along with a team of international researchers, created a very accurate and widespread “family tree” for cows and other ruminants, going back as far as 29 million years. This genetic information could allow researchers to understand the evolution of cattle, ruminants and other animals. This same technique also could be used to verify ancient relatives to humans, help farmers develop healthier and more efficient cattle, and assist researchers who are studying human diseases, as per the research, which is being published in this week’s edition of the Proceedings of the National Academy of Sciences (PNAS)……..
