Microcephalin and ASPM Genes Determine Human Brain Size - Genetics and Public Health Blog

Microcephalin and ASPM Genes Determine Human Brain Size - Genetics and Public Health Blog: "In the last 60,000 years, the human brain has continued to evolve. Two genes--microcephalin and ASPM--appear to play a role in determining the size of the human brain. They were first discovered in studies of microcephaly, a congenital disease in which people are born with smaller than average brains.

Brain size, however, isn't necessarily correlated with intelligence. The genes may be useful in some tangential way, such as increased fertility or resistance to disease. "
