There’s an excellent piece on human evolution in Newsweek, written for those of us who are not scientists. I think there are a couple of unclear points, but for the most part it’s a good update on the state of science. I did notice that things that have been around for some years seem to be considered brand new and exciting–exciting they certainly are, but the simple “begat” idea of human evolution has been weakening for a long time.
In any case, this is an article worth reading. I’ve seen the various pieces on more scientific blogs, but as an overview for the non-scientist, this one is good.
