Document Summary
In what way to dertebrate brains differ: all very similar. All things being equal, smaller animals have a proportionally larger brain cuvier (french scientist: smaller animals have greater proportion of their bodyweight dedicated to brain. Encephalization factor = a way of comparing bodyweight and brain weight: more comfortable. Natural order" intuitive sense of brain capacity encephalization factor = how far do you deviate form the expected" value/line. Humans deviate more from this line than any other animals. Measure of the importance of the role of the brain in species. Primates: bigger brains (in relation to body size, neocortical scaling greater (much of brain devoted to cerebrum/neocortex, some distinct architectures in neocortex not seen in non-primates. Evolution of grassland may have been a driver towards evolutionary change towards intelligence. Freeing forelimbs to allow hands to make tools etc: came out of trees, cultural explosion.
