つい最近まで、動物には複雑な思考はないとされ、研究もほとんどされてこなかった。ところが近年、動物の認知やコミュニケーションに関する研究が進むと、驚くべきことが分かってきた。例えば、小鳥のシジュウカラは仲間にウソをついてエサを得るそうだ。

What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the "Hockey Stick", a chart showing global temperature data over the past 1,000 years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.

There has been a lot of ink devoted to discussions of how robots will replace us and take our jobs. But MIT Media Lab researcher and technology policy expert Kate Darling argues just the opposite, and that treating robots with a bit of humanity, more like the way we treat animals, will actually serve us better.

A heartwarming account of the trials and triumphs a hummingbird rehabber encounters while caring for her tiny, fragile patients. This personal narrative is filled with the science and magic surrounding these fascinating creatures.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

The question of teaching evolution in the public schools is a continuing and frequently heated political issue in America. From Tennessee's Scopes Trial in 1925 to recent battles that have erupted in Louisiana, Kansas, Ohio, and countless other localities, the critics and supporters of evolution have fought nonstop over the role of science and religion in American public life. In American Genesis, Jeffrey P. Moran explores the ways in which the evolution debate has reverberated beyond the confines of state legislatures and courthouses.

A true scientific pause-resister that traces a remarkable scientific breakthrough (the isolation of endorphins in the brain) as dedicated scientists race - not only with their fellow scientists - but against time and the profit hungry giant pharmaceutical companies. This audiobook chronicles the fascinating discovery of endorphins, the body's natural painkiller.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

Qui aurait dit, il y a seulement quelques années, que les plantes étaient capables de réagir au vol d'une abeille, ou les corbeaux de réconforter un congénère blessé ? Qu'il suffisait aux poulpes d'observer un comportement pour le mémoriser, ou que des singes avaient créé un protolangage en associant plusieurs sons dans un même cri ? Non, Sapiens n'a pas le monopole de l'intelligence !

Our brains are more powerful than we ever realised. Too often, we assume that people's natures are fixed, immutable. For sufferers of depression, anxiety, ADHD, addiction, or the after-effects of stroke, this can be a difficult thought. For those with extreme conditions, such as locked-in syndrome or psychopathy, it can feel as if there is no hope at all. However, in Your Brain Knows More Than You Think, leading neurobiologist Niels Birbaumer turns these assumptions on their head.

In this revealing romp through the mysteries of human perception, University of California psychologist and researcher Lawrence Rosenblum explores the astonishing abilities of the five senses - skills of which most of us are remarkably unaware. Drawing on groundbreaking insights into the brain's plasticity and integrative powers, including findings from his own research, Rosenblum examines how our brains use the subtlest information to perceive the world.

The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behavior and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes.

What do you do when your world ends? At 28 years old, Krista Schlyer sold almost everything she owned and packed the rest of it in a station wagon bound for the American wild. Her two best friends joined her - one a grumpy, grieving introvert, the other a feisty dog - and together they sought out every national park, historic site, forest, and wilderness they could get to before their money ran out or their minds gave in.

Beginning in his kayak in his home waters of eastern Long Island, Carl Safina's The View from Lazy Point takes us through the four seasons to the four points of the compass, from the high Arctic south to Antarctica, across the warm belly of the tropics from the Caribbean to the west Pacific, then home again.

Every summer for two decades, Ted Leeson and a maverick group of close companions have returned to an old ranch house on the bench-land overlooking the Madison River. Trout and fly fishing may be at the heart of their ritual return, but their experience goes far beyond the fishing. Leeson contemplates both the human and natural landscape brilliantly....

An end to Roderick L. Haig-Brown’s seasons cycle, Fisherman’s Summer is a book that can be listened to again and again, for both knowledge and pleasure. In this installment, he focuses again on the rivers of his native British Columbia such as the Campbell, the Columbia, and the Nimpkish. Among his vast wealth of knowledge concerning fly fishing, listeners are also exposed to his wise reflections.

Today, taxonomy is viewed by many as an outdated field, one nearly irrelevant to the rest of science and of even less interest to the rest of the world. Now, as Carol Kaesuk Yoon reminds us in Naming Nature, taxonomy is critically important, because it turns out to be much more than mere science. It is also the latest incarnation of a long-unrecognized human practice that has gone on across the globe, in every culture, in every language since before time: the deeply human act of ordering and naming the living world.
