Brain chemistry might explain different evolutionary development of humans and apes

What makes us humans different from our close relatives, the chimpanzees, gorillas and other apes? The answer might lie in the neurochemistry of a particular brain region that modulates behaviour: the striatum. The human striatum harbours much more dopamine than that of apes, which could be at the basis of human altruistic and empathic behaviour. Increased use of dopamine might also have been important for the development of monogamy during human evolution.
