This edited volume challenges popular notions of sex, gender and biology and features international, trans-disciplinary research. The book begins with an exploration of supposedly ´natural´ sexual differences, then looks at research in evolutionary biology and examines topics such as gender stereotypes in humans.

The first chapters explore important questions: What are the fundamental sex differences? How do genes and hormones influence an individual´s sex? Subsequent chapters concern topics including: sex stereotypes in the field of sexual conflict, how the focus on genes in evolutionary biology disregards other means of inheritance, and the development of Darwin´s theory of sex differences.

The last three chapters look at humans, discussing: an interdisciplinary approach to the evolution of sex differences in body height, biological versus social constructive perspectives on the gendering of voices and nature-culture arguments in the current political debate on paternity leave in Norway.
