University of Toronto Press Biology of Sex

Biology of Sex is an interesting, lively, and intellectually challenging introduction to the biology of sex. Mills analyzes the biological basis of sex by introducing genetic, physiological, and evolutionary principles. In order to explain the biological aspects of human sex, he uses direct and intriguing comparisons with the many variations in sexual systems among non-human organisms. Text boxes provide fascinating examples of non-human species that cannibalize their partners during copulation, that do not fall within one of two biological sexes, and that "trick" others into raising their young. The author also explores questions such as "Is sex only for reproduction?" and "Why is sex fun?" Intended primarily for readers without a science background, Biology of Sex provides novel content from the non-human world to introduce the complex subject of sex and reproduction.
