I saw another post on this early this week, so I had to dive into the paper and dig around a little. It definitely seems less conclusive than advocated by media outlets, they state "we consider four principle alternative interpretations of its phylogenetic position: Graecopithecus is a stem-hominine (last common ancestor of African apes and Homo), a gorillin, a panin, or a hominin." There is no genetic information available as I understand, phylogenic classification is all we've got based on the mandable and such. They clearly state here on of their principle interpretations is that the ancestor is a hominid, gorillin or panin. None of which are an end-all human ancestor. There is lots of evidence to suggest most of the great apes evolved in africa some 10 million years ago, and for now I'll say humans probably were a result of these conditions as well. Might get through all the videos through just to see.
