Charles Darwin and Selection in Relation to Sex in the Colors of Monkeys

This chapter explores how Darwin’s theory of sexual selection has structured research on primate coloration. Darwin was fascinated by the conspicuous colors displayed by many animals and pointed to primates as a particularly colorful and interesting group. The chapter provides an overview of Darwin’s theory of sexual selection, highlighting how different selective mechanisms can lead to the extravagant colors found in many primate species. The chapter then overviews both modern and historical studies of primate coloration, emphasizing how methodological advances and a resurgence of interest in sexual selection has led to a modern revival of Darwin’s ideas regarding primate coloration. Finally, the chapter concludes with a discussion of future questions and possible directions of this research. Darwin’s collected works clearly show that he was captivated by the bright colors displayed by many primates, and his theory of sexual selection remains the key to understanding the evolution of many of these impressive traits.
