.. is definitely benefiting from its relationship from human beings,” she states. But that sort of marriage isn’t a thing that is simple to pinpoint employing DNA alone.
this can be a great commence, suggests Greger Larson, a paleogenomicist at Oxford, and it sets the stage for making use of historical chromosomal DNA to even more refine the story of ancient cats.
