The Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature by Geoffrey Miller is a groundbreaking exploration of human evolution. In this book, Miller presents a novel theory: that the human mind itself evolved as a result of sexual selection. Rather than merely being a side effect of surplus brain size, traits such as consciousness, morality, creativity, language, and art were actually sexual attractors. Miller draws on Darwin’s theory of sexual selection, which he argues has been overshadowed by Darwin’s theory of natural selection.
