Scientists Believe They Have Found Key Gene That Helped Human Brain Evolve From Apes

WASHINGTON Aug 17, 2006 (AP)— Scientists believe they have found a key gene that helped the human brain evolve from our chimp-like ancestors. In just a few million years, one area of the human genome seems to have evolved about 70 times faster than the rest of our genetic code. It appears to have a role in a rapid tripling of the size of the brain's crucial cerebral cortex, according to an article published Thursday in the journal Nature.

Study co-author David Haussler, director of the Center for Biomolecular Science and Engineering at the University of California, Santa Cruz, said his team found strong but still circumstantial evidence that a certain gene, called HAR1F, may provide an important answer to the question: "What makes humans brainier than other primates?" Human brains are triple the size of chimp brains.

However, the gene changed so fast that Clark said that he has a hard time believing it unless something unusual happened in a mutation. It's not part of normal evolution, he said. Haussler attributed the dramatic change to the stress of man getting out of trees and walking on two feet.
