How did the female body drive 200 million years of human evolution? Why do women live longer than men? Why are women more likely to get Alzheimer’s? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? Is sexism useful for evolution? And why, seriously why, do women have to sweat through our sheets every night when we hit menopause? These questions are producing some truly exciting science – and in this book, with boundless curiosity and sharp wit, Cat Bohannon covers the past 200 million years to explain the specific science behind the development of the female sex: “We have to put the female body in the picture. If we don't, it's not just feminism that's compromised. Modern medicine, neurobiology, paleoanthropology, even evolutionary biology all take a hit when we ignore the fact that half of us have breasts.”
