How Sex Works: Why We Look, Smell, Taste, Feel, and Act the Way We Do
by Sharon Moalem

Birds do it, bees do it, but why do humans do it? In this wide-ranging look at the evolutionary reasons for sex, physiologist and evolutionary biologist Sharon Moalem says that it's all about shuffling the gene pool and getting rid of any unwelcome guests, such as viruses, that may have latched onto human DNA. But why is one particular person attracted to another? Moalem relays the latest research showing that smell plays a very important role in attraction, and that even our genes may influence one's smell, and thus a person's desirability, to others. Chapters also cover puberty, factors in attraction and arousal, sexually transmitted diseases, and birth control.
