Jeff gets a jaw-shaped no-prize for bringing us this interesting summary of a new genetic finding in human origins research. A group of biologists and, of all things, a team of plastic surgeons have discovered a single mutation related to jaw size that may have been what kicked the genus Homo down the road to, well, us.

Unfortunately the article is long on sensationalism and very short on cogent details, so some of it doesn't make much sense. Still, a very interesting finding, hopefully BBCnews or NewScientist will put up a more detailed article soon. But you heard it here first! :)

Update: Yup, New Scientist has a much better summary. AP had better quotes (Wolpoff and Lovejoy are two of the top scientists in the field), but kudos to NS for actually explaining the damned thing.
