Can simulating evolution on a computer explain our enormous brains?

Compared to the rest of the animal kingdom, the human brain is way out of whack.

Our brains are roughly six times larger than what you would expect for a placental mammal of our stature, scientists say.

So why did humans evolve to have such large brains when other animals...Read more
