Bøger af Marlene Zuk

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behaviour evolve?Drawing from a wealth of research, including her own on insects, Zuk answers this question by turning to a wide range of animals and animal behaviour. There are stories of cockatoos that dance to rock music, ants that heal their injured companions, dogs that exhibit signs of obsessive-compulsive disorder and so much more.For insights into animal intelligence, mating behaviour and an organism's ability to fight disease, she explores the behaviour of smart spiders, silent crickets and crafty crows. In each example, she clearly demonstrates how these traits were produced by the complex and diverse interactions of genes and the environment and urges us to consider how that same process evolves behaviour in us humans.Filled with delightful anecdotes and fresh insights, Dancing Cockatoos and the Dead Man Test helps us see both other animals and ourselves more clearly, demonstrating that animal behaviour can be remarkably similar to human behaviour and wonderfully complicated in its own right.

We treat disease as our enemy. Germs and infections are things we battle. But what if we've been giving them a bum rap? From the earliest days of life on earth, disease has evolved alongside us. And its presence isn't just natural but is also essential to our health. Drawing on the latest research, Zuk answers a fascinating range of questions about disease: Why do men die younger than women? Why are we attracted to our mates? Why does the 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 we have sex at all, rather than simply splitting off copies of ourselves like certain geckos? And how is our obsession with cleanliness making us sicker? In this witty, engaging book, evolutionary biologist Zuk makes us rethink our instincts as she argues that disease is our partner, not our foe. Reconsider the fearsome parasite!

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.
