Instead, human brains think up all sorts of other, rather non-Darwinian things to do.…

The male and female human brains are different. Some of the better documented differences are similar to differences seen in other mammals. They are hard to find, very small, and may or may not be of great significance. Obviously, some are very important because they probably relate to such things as the ability … or…
