How did humans get big brains?
Over the last million years of evolution, our brain underwent a considerable increase in size and complexity, resulting in the exceptional cognitive abilities of the human species.
This brain enlargement is largely due to an increase in the number of neurons in the cerebral cortex, the outer part of the brain..
