A comparative look at the brain sizes of different species.
(via Frontiers)
Brain size is interesting if you compare it to body size. The larger the body, the more brain is needed to control it (muscles, glands, sensation etc.), but it is not a constant relationship. Humans have a brain-body mass ratio of 1/40. Horses 1/600. Small birds 1/14.
