WHY DO HUMANS HAVE LARGER BRAINS?


Humans have the largest brains in proportion to their body mass with the exception of ants whose brains make up 15% of their body mass. There are various theories about why this is so: the first is the trade off hypothesis, the second is the social brain theory, the third is the evolutionary advantage theory and the fourth is diet. Do your research and find out more about these theories and write an essay in which you discuss the reasons why humans have larger brains.
