Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. For some, there has never been a happier food era than today: a time of unusual herbs, farmers' markets, and internet recipe swaps.

This is a story about you. It is the history of who you are and how you came to be. It is unique to you, as it is for every one of the 100 billion modern humans who has ever drawn breath. But it is also our collective story, because in each of our genomes we carry the history of the whole of our species.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.

Lately, the most passionate advocates of the theory of evolution seem to present it as bad news. Scientists such as Richard Dawkins, Lawrence Krauss, and Sam Harris tell us that our most intimate actions, thoughts, and values are mere byproducts of thousands of generations of mindless adaptation. We are just one species among multitudes and therefore no more significant than any other living creature. Now comes Brown University biologist Kenneth R. Miller to make the case that this view betrays a gross misunderstanding of evolution.

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 September 1838, a young Englishman named Charles Darwin hit upon the idea that "natural selection" among competing individuals would lead to wondrous adaptations and species diversity. Twenty-one years passed between that epiphany and publication of On the Origin of Species. The human drama and scientific controversy of that time constitute a fascinating, tangled tale that illuminates this cautious naturalist who sparked an intellectual revolution.

Why did humans abandon hunting and gathering for sedentary communities dependent on livestock and cereal grains and governed by precursors of today's states? Most people believe that plant and animal domestication allowed humans, finally, to settle down and form agricultural villages, towns, and states, which made possible civilization, law, public order, and a presumably secure way of living. But archaeological and historical evidence challenges this narrative.

Why is the world the way it is? How did we get here? Does everything happen for a reason, or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world.

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

In this audiobook, The Human Odyssey, we explore the evolution of those characteristics that make us human. The first section looks at our family tree and why some branches survived and not others. Swings in climate are emerging as a factor in what traits succeeded and failed; meanwhile, DNA analyses show that Homo sapiens interbred with other human species, which played a key role in our survival.

Synthetic biology promises to reveal how life is created and how it can be re-created, enabling scientists to rewrite the rules of our reality. It could help us, for example, heal without prescription medications, grow meat without harvesting animals, or confront our looming climate catastrophe. Synthetic biology will determine the ways in which we conceive future generations and how we define family, how we identify disease and treat aging, where we make our homes, and how we nourish ourselves.

Just 150 years ago, most of our world was an unexplored wilderness. Our sense of its age was vastly off the mark. And what we believed to be the history of our own species consisted of fantastic myths and fairy tales; fossils, known for millennia, were seen as the bones of dragons and other imagined creatures. How did we learn so much so quickly? Remarkable Creatures celebrates the pioneers who replaced our fancies with the even more remarkable real story of how our world evolved.

Drawing on startling new evidence from the mapping of the genome, an explosive new account of the genetic basis of race and its role in the human story. Human evolution, the consensus view insists, ended in prehistory. Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years - to be lactose tolerant, for example, and to survive at high altitudes.

In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum - reviving Darwin's own views - thinks not.

Charles Darwin’s theories, first published more than 150 years ago, still set the paradigm of how we understand the evolution of life—but scientific advances of recent decades have radically altered that understanding. In fact the currently accepted history of life on Earth is flawed and out of date. Now two pioneering scientists, one already an award-winning popular author, deliver an eye-opening narrative that synthesizes a generation’s worth of insights from new research.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science--and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. A new preface shows how this witty, playful, and daring book has revolutionized our understanding of sexuality.

Hace 13.000 años la evolución de las distintas sociedades humanas comenzó a tomar rumbos diferentes. La temprana domesticación de animales y el cultivo de plantas silvestres en el Creciente Fértil, China, Mesoamérica y otras zonas geográficas otorgó una ventaja inicial a sus habitantes. Sin embargo, los orígenes localizados de la agricultura y la ganadería son solo una parte de la explicación de los diferentes destinos. Las sociedades que superaron esta fase de cazadores-recolectores se encontraron con más probabilidades de desarrollo, supervivencia y poder bélico.

What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells.

By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.
