Human Biology

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

Referring to Lewis Carroll's Red Queen from Through the Looking-Glass, a character who has to keep running to stay in the same place, Matt Ridley demonstrates why sex is humanity's best strategy for outwitting its constantly mutating internal predators.

This revised edition of Human Nature begins a new phase in the most important intellectual controversy of this generation: Is human behavior controlled by the species' biological heritage? Does this heritage limit human destiny?

With characteristic pungency and simplicity of style, the author of Sociobiology challenges old prejudices and current misconceptions about the nature-nurture debate.

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.

At first glance, human history is full of remarkable feats of intelligence. We invented writing. Produced incredible achievements in music, the arts, and the sciences. We’ve built sprawling cities and traveled across oceans—and space—and expanded to every part of the globe. Yet, human exceptionalism can be a double-edged sword. With our unique cognitive prowess comes severe consequences, including existential angst, violence, discrimination, and the creation of a world teetering towards climate catastrophe. Understood side-by-side, human exceptionalism begins to look more like a curse.

A giant of archaeology, Colin Renfrew has immeasurably improved our understanding of human history. In this passionately argued work, he offers a concise summary of prehistory - human existence that predates the development of written records - while challenging the very definition of prehistory itself.

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.

The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book.

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.

In this groundbreaking new book, researchers Andrew Newberg and Eugene d'Aquili offer an explanation that is at once profoundly simple and scientifically precise: The religious impulse is rooted in the biology of the brain. In Why God Won't Go Away, Newberg and d'Aquili document their pioneering explorations in the field of neurotheology, an emerging discipline dedicated to understanding the complex relationship between spirituality and the brain.

Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Works presents captivating new ideas and surprising answers to questions about contraception, fertility, circumcision, menopause, STDs, homosexuality, orgasms, and more. This is an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.

An eye-opening look into why our bodies work - or don’t - the way they do. From blurry vision to crooked teeth, ACLs (anterior cruciate ligaments) that tear at alarming rates and spines that seem to spend a lifetime falling apart, it’s surprising that human beings have beaten the odds as a species. After all, we’re the only survivors on our branch of the tree of life. In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us from where we inherited our adaptable, achy, brilliant bodies in the process of evolution.

Finally, answers to all those strange questions you'd like to ask your own doctor but haven't had the guts (or more likely the time) to do so.

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.

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.

There is a scientific revolution stirring in the field of human perception. Research has shown that the extraordinary sensory powers of our animal friends can help us better understand the same powers that lie dormant within us....

Our species has amassed unprecedented knowledge of nature, which we have tried to use to seize control of life and bend the planet to our will. In A Natural History of the Future, biologist Rob Dunn argues that such efforts are futile. We may see ourselves as life’s overlords, but we are instead at its mercy. In the evolution of antibiotic resistance, the power of natural selection to create biodiversity, and even the surprising life of the London Underground, Dunn finds laws of life that no human activity can annul.

Explore each organ of the body in this immersive audiobook adaptation of Kay's Anatomy, read by world-wide multi-million bestselling author and former doctor Adam Kay with a full cast of voices, including Mark Gatiss, Sandi Toksvig, Andy Nyman and Lolly Adefope.

Many people believe that, at its core, biological sex is a fundamental, diverging force in our development. According to this familiar story, differences between the sexes are shaped by past evolutionary pressures - women are more cautious and parenting-focused, men seek status to attract more mates - re-created in each generation by sex hormones and male and female brains. This, in turn, is the basis of supposedly entrenched inequalities in our modern societies.

The study of human evolution is advancing rapidly. Newly discovered fossil evidence is adding ever more pieces to the puzzle of our past, while revolutionary technological advances in the study of ancient DNA are completely reshaping theories of early human populations and migrations. In this Very Short Introduction, Bernard Wood traces the history of paleoanthropology from its beginnings in the 18th century to the very latest fossil finds.
