Dramatic change in brain chemistry may be the ultimate basis of human evolution

Mary Ann Raghanti, Ph.D., compared neurochemical profiles in the striatum, a brain region that modulates social behavior, among humans, chimpanzees, gorillas, and monkeys and found a unique profile in humans.

Researchers at Kent State University find evidence that an early shift in brain chemistry may have given our earliest ancestors an edge-
