Richard O. Prum

A major reimagining of how evolutionary forces work, revealing how mating preferences--what Darwin termed "the taste for the beautiful"--create the extraordinary range of ornament in the animal world. In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

How Darwin's Forgotten Theory of Mate Choice Shapes the Animal World - and Us

The Evolution of Beauty

A major reimagining of how evolutionary forces work, revealing how mating preferences—what Darwin termed "the taste for the beautiful"—create the extraordinary range of ornament in the animal world. "A delicious read, both seductive and mutinous.... Minutely detailed, exquisitely observant, deeply informed, and often tenderly sensual."—New York Times Book Review In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves.

An award-winning biologist and writer applies queer feminist theory to developmental genetics, arguing that individuals are not essentially male or female. The idea that gender is a performance—a tenet of queer feminist theory since the nineties—has spread from college classrooms to popular culture. This transformative concept has sparked reappraisals of social expectations as well as debate over not just gender, but sex: what it is, what it means, and how we know it. Most scientific and biomedical research over the past seventy years has assumed and reinforced a binary concept of biological sex, though some scientists point out that male and female are just two outcomes in a world rich in sexual diversity. In Performance All the Way Down, MacArthur Fellow and Pulitzer Prize finalist Richard O. Prum brings feminist thought into conversation with biology, arguing that the sexual binary is not essential to human genes, chromosomes, or embryos. Our genomes are not blueprints, algorithms, or recipes for the physical representation of our individual sexual essences or fates. In accessible language, Prum shows that when we look closely at the science, we see that gene expression is a material action in the world, a performance through which the individual regulates and achieves its own becoming. A fertilized zygote matures into an organism with tissues and organs, neurological control, immune defenses, psychological mechanisms, and gender and sexual behavior through a performative continuum. This complex hierarchy of self-enactment reflects the evolved agency of individual genes, molecules, cells, and tissues. Rejecting the notion of an intractable divide between the humanities and the sciences, Prum proves that the contributions of queer and feminist theorists can help scientists understand the human body in new ways, yielding key insights into genetics, developmental biology, physiology. Sure to inspire discussion, Performance All the Way Down is a book about biology for feminists, a book about feminist theory for biologists, and a book for anyone curious about how our sexual bodies grow.

Genes, Development, and Sexual Difference

Performance All the Way Down

"We are living through a time of enormous cultural change involving broad reconsideration of ideas about individual sex, gender, their boundaries, their meanings, and their mutabilities. There is a growing realization of the diversity of lived gender identities and sexual experiences. Performance All the Way Down is a manifesto for today. It initiates needed dialogue between feminist thought and the science of sex by explaining all the avenues of sexual differentiation from zygote to gendered adult to argue, with an absorbing clarity, against the existence of the sexual binary. Richard O. Prum, author of The Evolution of Beauty, turns his attention in this book from beauty to sex. What is sex? And what does it mean, scientifically, to question the essentialist, binary concept of sex? Performance All the Way Down poses a new view on these complex questions. For Prum argues that the ways in which a single-celled, fertilized zygote becomes a complex, conscious organism with gender and sexual behavior is best described scientifically as a complex performative continuum. His idea of the performative phenotype challenges the twentieth century isolation of developmental biology from evolutionary biology and the strict conception of gene-level selection, providing an alternative view of what being genetic actually means"--
