Researchers Say Human Brain is Still Evolving

Oleg Alexandrov writes "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."

      It would be great if the human brain would evolve in such a way that it would be repulsive to zombies, and they wouldn't want to eat out brains any more.

      that's not far off. I was having serious problems I won't bore you with in my GI tract during a very depressed spell in my life. I went to a doctor who told me it was psychosomatic and that I should see a psychiatrist. I did, and I went onto SSRIs (Selective Serotonin Reuptake Inhibitors). I talked to him about the connection between stomach and mood and he told me that you have more serotonin in your stomach than you do in your brain.

      Oh yeah, he also told me that your sinuses are an erectile organ, and there are many people who report changes in the open- or closedness of their sinuses leading up to and during arousal.
