“The earliest ancestors of old-world monkeys, apes and humans had surprisingly small brains, a new study shows.

This finding – based on a newly described fossil skull – means that large brains evolved independently in new- and old-world primates. It also suggests that evolutionary anthropologists may have to rethink some cherished theories about why such big, powerful brains evolved.”
