Cerebral development in chimpanzees: Human intelligence secrets revealed by chimp brain
Like humans, chimps are born with immature forebrains
In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, ...
