EATING FRUIT LINKED TO BIGGER BRAIN

Larger and more complex brains in humans and primates have been found to have a strong link to diet, particularly to fruit.  Researchers at New York University found that fruit-eating primates have around 25% more brain tissue than other plant-eating species.  They had two explanations: (ii) bigger brains probably evolved from the hunter/gatherer instinct, primates having to recall fruit locations and work out new ways to extract flesh from tough skins and (ii) fruit also have higher energy and nutrients than most plants and hence boost growth.  Full story:
