Human Biology

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

In this groundbreaking work, evolutionary biologist Jared Diamond stunningly dismantles racially based theories of human history by revealing the environmental factors actually responsible for history's broadest patterns. It is a story that spans 13,000 years of human history, beginning when Stone Age hunter-gatherers constituted the entire human population. Guns, Germs, and Steel is a world history that really is a history of all the world's peoples, a unified narrative of human life.

We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

Throughout history, even as daily life has exhibited calm and tolerance, war has never been far away, and even within societies, violence can be a threat. The Goodness Paradox gives a new and powerful argument for how and why this uncanny combination of peacefulness and violence crystallized after our ancestors acquired language in Africa a quarter of a million years ago.

Edward is a geeky 18-year-old student who lusts after his voluptuous science teacher, like every other boy in the school. The difference is Edward's a genius. Combining his love for hypnosis with his genius for electronics, he has invented a machine that will bend any woman's mind to his will. The science teacher is herself about to become the subject of an experiment.

How were graham crackers and Kellogg's cornflakes supposed to stop masturbation? Why was the Catholic church so insistent that sex could only be performed in the missionary position? In this book, you will find out why to testify meant to grab someone else’s testicles, and why young boys in Papua New Guinea thought they had to drink older men’s semen to attain puberty. St. Augustine believed that semen was a fluid that transmits Adam’s original sin to every unborn child, Chinese and Indian scholars thought that it gives a person vitality. This book will tell you the ancient secret of ...

Physiological constraints confine our bodies to less than one-fifth of the earth's surface. Beyond that fraction lie the extremes. What happens when we go to them? Dr. Kenneth Kamler has spent years observing exactly what happens. A vice president of the legendary Explorers Club, he has climbed, dived, sledded, floated, and trekked through some of the most treacherous and remote regions in the world. A consultant for NASA, Yale University, and the National Geographic Society, he has explored undersea caves, crossed the frozen Antarctic wastelands, and more.

Gluttony. Greed. Sloth. Pride. Envy. Lust. Anger. These are The Seven Deadly Sins, the vices of humankind that define immorality. But do these sins really represent moral failings, or are they simply important and useful biological functions that humans need to survive? Instead of being acts of immorality, are they really just a result of how our bodies, our psyches, and our brains in particular, are wired? In Seven Deadly Sins, Guy Leschziner, a professor of neurology, dares to turn much of what society thinks of as morality on its head and to ask these controversial questions.

For over three decades, Ray Kurzweil has been one of the most respected and provocative advocates of the role of technology in our future. In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: The union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

In the late 1600s, a distinguished English polymath, Robert Hooke, and an eccentric Dutch cloth merchant, Antonie van Leeuwenhoek, look down their handmade microscopes. What they see introduces a radical concept that sweeps through biology and medicine, touching virtually every aspect of the two sciences and altering both forever. It is the fact that complex living organisms are assemblages of tiny self-contained, self-regulating units. Our organs, our physiology, our selves—hearts, blood, brains—are built from these compartments. Hooke christens them 'cells'.

Early studies of the human brain used a simple method: Wait for misfortune to strike - strokes, seizures, infectious diseases, horrendous accidents - and see how victims coped. In many cases their survival was miraculous, if puzzling. Observers were amazed by the transformations that took place when different parts of the brain were destroyed, altering victims' personalities. With the lucid, masterful explanations and razor-sharp wit his fans have come to expect, Kean explores the brain's secret passageways.

We have lost the war on cancer. We spend $150 billion each year treating it, yet - a few innovations notwithstanding - a patient with cancer is as likely to die of it as one was 50 years ago. Most new drugs add mere months to one's life at agonizing physical and financial cost. In The First Cell, Azra Raza offers a searing account of how both medicine and our society (mis)treats cancer, how we can do better, and why we must.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology.

Ambika Kamath and Melina Packer reveal how scientists studying animal behavior have long projected human norms and values onto animals while seeking to understand them. When scientific studies conclude that these norms and values are natural in animals, it makes it easier to think of them as natural in humans too. And because scientists, historically and to this day, largely belong to elite, powerful segments of society, the norms and values embedded into animal behavior science match those of the already powerful.
