In Depth
Although Nakalipithecus is so far only known from a jaw bone, Nakalipithecus has been a major contribution to our understanding of hominid evolution specifically regarding hominines, including the ancestors of humans. For some time there have been two competing theories regarding the ancient origins of our own direct ancestors, concerning either an African or Asian origin. Our own immediate ancestors seem to be African, but their ancestors have seemed to be from Asia. What the discovery of Nakalipithecus has shown us that early appearing and primitive members of the Homininae (the group that humans are classed in) were actually living in Africa at the same approximate time as ancestral forms in Asia, perhaps even earlier. What this means (and unless future research proves otherwise), is that the Asian origin of homonines theory is no longer as convincing as it used to be.
