The evolution of human batin play an important role in the solving the complex problems and situation.
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. Brain size increased rapidly during human evolution due to the expansion of many brain regions, resulting in human brains being exceptionally larger than those of our closest relatives.
