Skull Fossil Suggests Simpler Human Lineage

After eight years spent studying a 1.8-million-year-old skull uncovered in the Republic of Georgia, scientists have made a discovery that may rewrite the evolutionary history of our human genus Homo.

It would be a simpler story with fewer ancestral species. Early, diverse fossils — those currently recognized as coming from distinct species like Homo habilis, Homo erectus and others — may actually represent variation among members of a single, evolving lineage.

In other words, just as people look different from one another today, so did early hominids look different from one another, and the dissimilarity of the bones they left behind may have fooled scientists into thinking they came from different species.

Or not . . . it's more of an open question now. It seems to me that the biggest significance of the find is that hominids migrated out of Africa a lot earlier than previously thought.

Hmmm, now that could mean more instances of isolated populations, and more opportunities for divergent evolution. Back to square one.

I'm not a biologist, so take this with a grain of salt, but I'm skeptical that the discovery of this skull necessarily means the current model of human evolution is flawed. It may just mean that the species we find (Homo habilis, etc.) may be evolutionary "cousins" that descend from different, but related, species along the human-related evolutionary line, while modern humans descent from an entirely separate (but related) lineage.

Regardless, I just really hope the creationists don't use this discovery as "evidence" for their asinine worldview.

I'm very skeptical of this, I think there is a whole lot we don't know about human evolution, splits, lineages etc.
