TT, well in one way. But in fact this just pushes the earliest common ancestor back that far. This could have been inherited from an ancestor of the modern humans. So the modern human race doesn't have to be that old. I think it depends on how you define human. That is one of the things that is quite controversial. Just figuring out whether a fossil is a member of genus homo can be tricky. If this report winds up being accepted than it just says that whoever the common ancestor was probably a member of genus homo.

In fact the abstract points out that this could be a result of crossbreeding between modern humans and a related species the way they have found that there was crossbreeding between modern humans and Neanderthals.
