DNA extracted from the bone belongs to a mysterious ancient hominin that last shared an ancestor with our species and Neanderthals about a million years ago.

An international team of scientists, including one from the University of Colorado Denver and another from the University of Colorado Anschutz Medical Campus in Aurora, announced the discovery Thursday of a new species of hominin, a small creature with a tiny brain that opens the door to a new way of thinking about our ancient ancestors.

But the new adult skull shows that the hominins combined this ancient feature with a small, lightly built «modern» face — one that the researchers say is virtually indistinguishable from H. sapiens.

But ancient - DNA sequencing is beginning to shed some light on the issue.11 For example, by comparing a human HAR sequence with the HAR sequence of an archaic hominin, researchers can estimate if the HAR mutated before, after, or during the time period of our common ancestor.12 This approach has revealed that the rate at which HAR mutations emerged was slightly higher before we split from Neanderthals and Denisovans.3, 13 As a result, most HAR mutations are millions of years old and shared with these extinct hominins (but not with chimpanzees).

«Once we've refined our technique to the point that we need smaller sample amounts and are able to obtain ancient hominin fossils from Africa, we may eventually be able to classify them into two groups — those that have Gc - CS and those that do not.

How these ancient hominins would have gotten to Indonesia from Africa is, of course, a mystery.
