Early Humans May Have Evolved Bigger Brains Eating Insects, Washington University in St. Louis Study

A new study, led by Washington University in St. Louis, suggests that seasonal diet changes may have played a role in the development of bigger brains and higher-level cognitive functions in human ancestors and other primates. The findings, published in the Journal of Human Evolution, show that figuring out how to survive on a lean-season diet of hard-to-reach ants, slugs and other bugs might have been the catalyst for early tool use.
