Human Brain Evolution: Scientists Identify Area That Separates Us From Primates

Apes are our closest animal relatives. We share 99.5 percent of our DNA material with them, but the 0.5 percent we do not share creates the vast differences between the two species. The differences are seen in physical features and intelligence. Most regions in our brain are, on a molecular level, very similar to primate brains. The various regions of the human brain have a similar structure and function as our primate relatives.
