Current thinking on diet and brain evolution?

[QUOTE="Laroxe, post: 6284349, member: 555853"] There are always problems in ideas that talk about things in the environment driving evolution, this is a bit back to front really, things have to be present to be selected and presumably a larger brain would help in securing adequate food. Other primates are often quite happy to scavenge meat and some hunt so its very difficult to make any sort of generalised guess about the early diet of human groups. It seems that very quickly chose to concentrate in areas that had high protein food sources like coastlines or near rivers and we certainly didn't evolve to live in a particular environment following a particular lifestyle. In terms of the brain the main issue would be its high energy requirements rather than protien rich foods. Our big advantage was in our adaptability and as mentioned our cooperative nature. While meat is certainly a nutritionally dense food source humans can survive quite well on a plant based diet for this to be a controlling factor in brain development we would have to imagine a state of chronic starvation really and that would still effect brain development.
