Sarah Hrdy argues that if human babies were to survive in a world of scarce resources, they would need to be cared for, not only by their mothers but also by siblings, aunts, fathers, friends—and, with any luck, grandmothers. Out of this complicated and contingent form of childrearing, says Hrdy, came the human capacity for understanding others.

What does it mean to be female? Sarah Blaffer Hrdy--a sociobiologist and a feminist--believes that evolutionary biology can provide some surprising answers. Surprising to those feminists who mistakenly think that biology can only work against women. And surprising to those biologists who incorrectly believe that natural selection operates only on males. In The Woman That Never Evolved we are introduced to our nearest female relatives competitive, independent, sexually assertive primates who have every bit as much at stake in the evolutionary game as their male counterparts do. These females compete among themselves for rank and resources, but will bond together for mutual defense. They risk their lives to protect their young, yet consort with the very male who murdered their offspring when successful reproduction depends upon it. They tolerate other breeding females if food is plentiful, but chase them away when monogamy is the optimal strategy. When "promiscuity" is an advantage, female primates--like their human cousins--exhibit a sexual appetite that ensures a range of breeding partners. From case after case we are led to the conclusion that the sexually passive, noncompetitive, all-nurturing woman of prevailing myth never could have evolved within the primate order. Yet males are almost universally dominant over females in primate species, and Homo sapiens is no exception. As we see from this book, women are in some ways the most oppressed of all female primates. Sarah Blaffer Hrdy is convinced that to redress sexual inequality in human societies, we must first understand its evolutionary origins. We cannot travel back in time to meet our own remote ancestors, but we can study those surrogates we have--the other living primates. If women --and not biology--are to control their own destiny, they must understand the past and, as this book shows us, the biological legacy they have inherited.

"The Langurs of Abu will for many years remain one of the major studies of wild primates, both for its observational and theoretical content." --Alison Jolly Sexual combat is not a monopoly of the human species. As Sarah Blaffer Hrdy argues in this spellbinding book, war between male and female animals has deep roots in evolutionary history. Her account of family life among hanuman langurs--the black-faced, gray monkeys inhabiting much of the Indian subcontinent--is written with force, wit, and at times, sorrow. Male hanumans, in pursuit of genetic success, routinely kill babies sired by their competitors. The mothers of endangered infants counter with various strategems to deceive the males and prevent destruction of their own offspring. Competition and selfishness are dominant themes of langur society. Competition among males for access to females, competition among females for access to food resources, and disregard by one female for the well-being of another's infant--these are some very common examples. Yet there are also moments of heroic self-sacrifice, as when an elderly female rushes to defend her troop and its babies from an invading, infancticidal male. The Langurs of Abu is the first book to analyze behavior of wild primates from the standpoint of both sexes. It is also a poignant and sophisticated exploration of primate behavior patterns from a feminist point of view. This book may inspire controversy; it will certainly be read with pleasure by anyone interested in animal behavior. Richly illustrated with photographs, seven in full color.

"A masterful synthesis of how it came to be that today men are taking care of very young babies given that this is unprecedented in the history of mammals, apes, and humans"--

Recent field studies of a variety of mammalian species reveal a surprisingly high frequency of infanticide - the killing of unweaned or otherwise maternally dependent offspring. Similarly, studies of birds, fish, amphibians, and invertebrates demonstrate egg and larval mortality in these species, a phenomenon directly analogous to infanticide in mammals. In this collection, Hausfater and Hrdy draw together work on animal and human infanticide and place these studies in a broad evolutionary and comparative perspective.Infanticide presents the theoretical background and taxonomic distribution of infanticide, infanticide in nonhuman primates, infanticide in rodents, and infanticide in humans. It examines closely sex allocation and sex ratio theory, surveys the phylogeny of mammalian interbirth intervals, and reviews data on sources of egg and larval mortality in a variety of invertebrate and lower vertebrate species. Dealing with infanticide in nonhuman primates, two chapters critically examine data on infanticide in langurs and its broader theoretical implications. By reviewing sources of infant mortality in populations of small mammals and new laboratory analyses of the causes and consequences of infanticide, this work explores such issues as the ontogeny of infanticide, proximate cues of infants and females which elicit infanticidal behavior in males, the genetical basis of infanticide, and the hormonal determinants.Hausfater and Sarah Blaffer Hrdy, through their selection of materials for this book, evaluate the frequency, causes, and function of infanticide. Historical, ethnographic, and recent data on infanticide are surveyed. "Infanticide" summarizes current research on the evolutionary origins and proximate causation of infanticide in animals and man. As such it will be indispensable reading for anthropologists and behavioral biologists as well as ecologists, psychologists, demographers, and epidemiologists.

The author dispels some of the myths about the nature of females and female sexuality, and suggests new hypotheses aboutthe evolution of women.

We are tempted to think of maternal instinct as a quality a woman has or lacks. But the belief that mothers instinctively nurture their offspring--one of the West's most cherished ideals and a view widely accepted even in scientific circles--has become increasingly controversial. Mother Nature presents a radical new way of understanding how mothers act and why, and how this new understanding is changing the way scientists think about how evolution works. Drawing on anthropology, history, literature, developmental psychology, and animal behavior, Sarah Hrdy examines the distinct biological and genetic elements that constitute maternal instinct. She strips away the biases implicit in conventional stereotypes of female nature to give us very different and provocative perspectives on maternal ambivalence, the links between maturity and ambition, mother love and sexual love, and why age-old tensions between the sexes persist--and are being played out today in efforts to control women's reproductive choices. Combining decades of research with her own experience as a mother, Hrdy makes clear in this remarkable book what it means--from a historical and evolutionary perspective--to be a mother and explains how this knowledge has transformed our understanding of human development and behavior.

Mother Nature is the big new popular science book for the end of the millennium. It starts from the standpoint of Darwinist evolutionary theory, but turns it on its head. It is the first such major book by a women, qho ia professor of SocioBiology at the University of California, trained in Anthropology and an expert on Primates in particular. She's also one of the few women members fo the US Academy of Sciences. It's not for nothing that Nature is known as Mother Nature. Evolution is controlled, Hrdy demonstrates, not by the male of species, but by the female who is more diverse, deadlier and more adaptable for her own and for evolutionary purposes (which are one and the same thing) than the male. It is thus the female who ultimately controls the perpetuation and evolution of her family/tribe/race/species right through nature. The notion of 'maternal instinct', with it baggage of self-sacrifice, gentleness and devotion, is not just a myth but a misapprehension. In fact, strong, aggressive 'maternal' behaviour is the ultimate manifestation of the 'selfish' gene.
