Document Summary

Almost exponential brain size increase and encephalization. Encephalization quotient (eq): a formula allowing comparison of brain sizes of different species while holding body size constant. 1 represents an equal correlation of brain size to body size6. Group social interaction is more cognitively complex than most other behaviour. We need our big brains to carry out complex social interactions. Theory of mind we can understand what others are thinking. We are able to cooperarate to achieve a shared goal. Theory that our brains developed to communicate orally with complex language. Complex language is essential in teaching and learning is essential in passing on information to evolve. Language allows individuals to more accurately and directly express their desires and intentions. Language may have been developed as a method of dissembling, to give others an incorrect belief of what we are thinking/feeling, akin to lying, kind of, putting on a brave face etc. The general trend in encephalization has to predate language.
