Single gene differentiates human brain from other

WillWare writes "Articles at New Scientist and EurekAlert discuss a finding that a single mutated gene may account for the larger size of human brains relative to those of other primates. The gene involved appears to influence or control the muscle mass used by the jaw in biting. In humans the bite muscle is weak, and consequently the skull is permitted to grow larger and permit the brain to do likewise. This might affect the feasibility of the Open-source Bonobo project."
