Breaking news; see this NY Times story. Two separate genes for brain size have been shown to have developed rapidly in recent times under selection, one since -37,000 (Cro-Magnon era), the other since only -5300 (neolithic, just before writing invented). The papers describing the research are in the current issue of Science.

great article! the work will have major repercussions and start a lot of other followup research I think

Here is a press release about this work from the Howard Hughes Medical Institute, and another HHMI link about Bruce Lahn
