Our unique human brain

During human evolution, our forebrain became larger as our cerebral cortex increased in size. This means it had to become more folded to fit inside the skull. This gives the outside of the human brain its 'walnut' appearance. Humans have a larger cerebral cortex relative to the rest of the brain than any other animal. The cerebral cortex handles many of our unique skills, like language and problem solving.
