Brain Size

Brain size is one aspect of animal anatomy and evolution. Both overall brain size and the size of substructures have been analysed, and the question of links between size and functioning - particularly intelligence - has often proved controversial. Brain size is sometimes measured by weight and sometimes by volume (via MRI scans or by skull volume).

Once the question mark has arisen in the human brain the answer must be found, if it takes a hundred years. A thousand years.
