We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived and why we should emulate them are often based on speculation, not scientific evidence.

Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized, meaning that we are not biologically the same as our caveman ancestors. Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. And women don t go into shoe-shopping frenzies because their prehistoric foremothers gathered resources for their clans. As Zuk compellingly argues, such beliefs incorrectly assume that we re stuck finished evolving and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults ability to drink milk to the texture of our ear wax to show that we ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were meant to fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs.

From debunking the caveman diet to unraveling gender stereotypes, Zuk delivers an engrossing analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future."

It's time to leave behind the tired nature-versus-nurture debate. In Dancing Cockatoos and the Dead Man Test , Marlene Zuk asks a more fascinating question: How does behaviour evolve, and how is that process similar-and different-in people and animals? Drawing from a wealth of research, including her own on insects, she explores how genes and the environment work together to produce cockatoos that dance to rock music and ants that heal their injured companions. She follows the different paths cats and dogs took to living with humans and asks whether bees are domestic animals. In exploring intelligence, mating behaviour and fighting disease, Zuk turns to smart spiders, silent crickets and crafty crows. She shows how neither our behaviour nor that of other animals is dictated solely by genes, and that animal behaviour can be remarkably similar to human behaviour-and wonderfully complicated in its own right.

What is responsible for the differences between the sexes in so many animals, from the brilliant plumage of birds of paradise to the antlers on deer? And why are the traits that distinguish the sexes sometimes apparently detrimental to survival? Even when they look more or less alike, why do males and females sometimes behave differently? Questions like these have intrigued scientists and the public alike for many years, and new discoveries are showing us both how wildly variable the natural world is, and how some basic principles can help explain much of that variation. Like natural selection, sexual selection is a process that results from differential representation of genes in successive generations. Under sexual selection, however, the crucial characteristics that determine whether an individual reproduces depend on sexual competition, rather than survival ability. This Very Short Introduction considers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds, and how sexual conflict is resolved in different species. They conclude with a consideration of the thorny question of how, and even if, sexual selection theory applies to humans. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Scientific discoveries about the animal kingdom fuel ideological battles on many fronts, especially battles about sex and gender. We now know that male marmosets help take care of their offspring. Is this heartening news for today's stay-at-home dads? Recent studies show that many female birds once thought to be monogamous actually have chicks that are fathered outside the primary breeding pair. Does this information spell doom for traditional marriages? And bonobo apes take part in female-female sexual encounters. Does this mean that human homosexuality is natural? This highly provocative book clearly shows that these are the wrong kinds of questions to ask about animal behavior. Marlene Zuk, a respected biologist and a feminist, gives an eye-opening tour of some of the latest developments in our knowledge of animal sexuality and evolutionary biology. "Sexual Selections" exposes the anthropomorphism and gender politics that have colored our understanding of the natural world and shows how feminism can help move us away from our ideological biases. As she tells many amazing stories about animal behavior - whether of birds and apes or of rats and cockroaches - Zuk takes us to the places where our ideas about nature, gender, and culture collide. Writing in an engaging, conversational style, she discusses such politically charged topics as motherhood, the genetic basis for adultery, the female orgasm, menstruation, and homosexuality. She shows how feminism can give us the tools to examine sensitive issues such as these and to enhance our understanding of the natural world if we avoid using research to champion a feminist agenda and avoid using animals as ideological weapons. Zuk passionately asks us to learn to see the animal world on its own terms, with its splendid array of diversity and variation. This knowledge will give us a better understanding of animals and can ultimately change our assumptions about what is natural, normal, and even possible.

We treat disease as our enemy, and germs and infections as things we battle. But what if we've been giving them a bum rap? In this witty, engaging book, evolutionary biologist Zuk makes us rethink our instincts as she argues that disease is our partner, not our foe.From the earliest days of life on earth - parasites spurred the creation of complex life forms - disease has evolved alongside us, becoming not only natural but essential to our health. Drawing on the latest research and most unusual studies, Zuk explains the role of disease in answering a fascinating range of questions: Why do men die younger than women? Why are we attracted to our mates? Why does your average male bird not have a penis? Why do we - as well as insects, birds, pigs, cows, goats, and even plants - get STDs? Why do vultures have yellow heads and roosters have red wattles? Why do we have sex at all, rather than simply splitting off copies of ourselves like certain geckoes? And how is our obsession with cleanliness making us sicker?
