Slashdot linked up news that some scientists are claiming to have discovered evidence that our brains are still evolving:

Two genes involved in determining the size of the human brain have undergone substantial evolution in the last 60,000 years, researchers say, suggesting that the brain is still undergoing rapid evolution.

The discovery adds further weight to the view that human evolution is still a work in progress, since previous instances of recent genetic change have come to light in genes that defend against disease and confer the ability to digest milk in adulthood.

The claim appears to already have set off a storm of controversy, and pretty much everyone seems to be admitting this is just one of several different interpretations of the data. The truth is, nobody's completely sure just what these genes actually do.
