Human Evolutionary Rate Study

There seems to be some interesting things going on with the recently reported study of rates of evolution in humans. We are getting reports of a wide range of rather startling conclusions being touted by the researchers who wrote this paper. These conclusions typically come from press releases, and then are regurgitated by press outlets, then read and reported by bloggers, and so on. Here is, in toto, the press release from the University of Wisconsin, where John Hawks, one of the authors of the study, works. I reproduce the press release here without further comment.

From an MIT press release:

A missing brain protein may be one of the culprits behind autism and other brain disorders, according to researchers at MIT’s Picower Institute for Learning and Memory.The protein, called CASK, helps in the development of synapses, which neurons use to communicate with one another and which underlie our ability to learn and remember. Improperly formed synapses could lead to mental retardation, and mutations in genes encoding certain synaptic proteins are associated with autism.
