Many evolutionary biologists believe the increased in the size of the brain relative to the body size in animals such as primates was driven by the demands of living in societies. This is known as the social – or Machiavellian – intelligence hypothesis.

- “Social interactions seem to impose important cognitive challenges that must be met by enhanced investment in certain brain regions”
