Evolution of the Human Brain :
Evolution of the Human Brain There is no relationship between brain size and intelligence
Brain size is generally correlated with body size
More informative to look at relative size of different brain regions
Evolution of theHuman Brain(continued) :
Evolution of theHuman Brain(continued) The brains of animals of different evolutionary age. The cerebrums are shown in yellow; the brainstems are shown in purple.
Evolution of the Human Brain (continued) :
Evolution of the Human Brain (continued) The human brain has increased in size during evolution
Most of the increase in size has occurred in the cerebrum
Increased convolutions in the cerebrum have served to increase the volume of the cerebral cortex
