Ancient DNA traces the woolly mammoth's disappearance

ome time before sixty thousand years ago. Moreover, they found two distinct genetic groups, implying that mammoths had diverged in isolation for some time before merging back into a single population. The DNA further suggests that no later than forty thousand years ago, one of the groups died out, leaving only the second alive at the time of the mammoth’s last gasp.

“At a time when we should be very concerned about the potential extinction of many existing large mammals, studying those that occurred in the geologically recent past can provide many insights,” Lister said. “Our work, together with that of others, shows that the conditions for extinction can be set up long before the actual extinction event.”
