Two new Homo fossils are described in this week’s Nature showing that H. erectus and H. habilis had co-existed for nearly half a million years.

Rather than ask, “This is really interesting. I wonder what this means?” some seem content to sit back, quote Scripture, and gleefully say “See! I was right all along! Case closed!”

These discoveries do not put evolution in doubt. Just as your mother’s life most likely substantially overlapped with your own, the persistence of a parental species so that it overlaps in time with its daughter species is not a challenge to evolution at all. Here is an excellent post by PZ Myers on just this.

Also a paleoanthropologist weighs in.
