In an article today published in the New York Times titled 'Brain May Still Be Evolving, Studies Hint' it suggested that the genes which influence brain evolution are still active:
"Two genes involved in determining the size of the human brain have undergone substantial evolution in the last 60,000 years, researchers say, leading to the surprising suggestion that the brain is still undergoing rapid evolution.
The discovery adds 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.
It had been widely assumed until recently that human evolution more or less stopped 50,000 years ago."
Finally, they recognise that our species-evolution hasn't finished yet!
