The Origin of Humankind is Richard Leakey's personal view of the development of Homo sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: Once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes.

Breakthroughs in genetics present us with a promise and a predicament. The promise is that we will soon be able to treat and prevent a host of debilitating diseases. The predicament is that our newfound genetic knowledge may enable us to manipulate our nature - to enhance our genetic traits and those of our children. Although most people find at least some forms of genetic engineering disquieting, it is not easy to articulate why.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

Biology is undergoing a quiet but profound transformation. Several aspects of the standard picture of how life works—the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular machines, of cells as entities with fixed identities, and more—have been exposed as incomplete, misleading, or wrong. In How Life Works, Philip Ball explores the new biology, revealing life to be a far richer, more ingenious affair than we had guessed.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. In spite - or even because - of the disgraceful hostility provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.

In his classic study The Expanding Circle, Peter Singer argues that altruism began as a genetically based drive to protect one's kin and community members but has developed into a consciously chosen ethic with an expanding circle of moral concern. Drawing on philosophy and evolutionary psychology, he demonstrates that human ethics cannot be explained by biology alone.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

In one of the great ironies of the modern world, the science that was expected to solve life’s mysteries has done just the opposite. New discoveries have led to more unanswered questions, created deeper mysteries, and brought us to the brink of forbidden territory when it comes to explaining our origin and existence. New York Times best-selling author and 2018 Templeton Award nominee Gregg Braden crosses the traditional boundaries of science and spirituality to answer the timeless question at the core of our existence.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

"Creativity is the unique and defining trait of our species, and its ultimate goal, self-understanding", begins Edward O. Wilson's sweeping examination of the humanities and its relationship to the sciences. By studying fields as diverse as paleontology, evolutionary biology, and neuroscience, Wilson demonstrates that human creativity began not 10,000 years ago, as we have long assumed, but over 100,000 years ago in the Paleolithic Age.

Best-selling author Brian Fagan brings early humans out of the deep freeze with his trademark mix of erudition, cutting-edge science, and vivid storytelling. Cro-Magnon reveals human society in its infancy, facing enormous environmental challenges - including a rival species of humans, the Neanderthals. For ten millennia, Cro-Magnons lived side by side with Neanderthals, an encounter that Fagan fills with drama.

The domestic cat—your cat—has, from its evolutionary origins in Africa, been transformed in comparatively little time into one of the most successful and diverse species on the planet. Jonathan Losos, writing as both a scientist and a cat lover, explores how researchers today are unraveling the secrets of the cat, past and present, using all the tools of modern technology, from GPS tracking (you’d be amazed where those backyard cats roam) and genomics (what is your so-called Siamese cat . . . really?) to forensic archaeology.

Why do minds exist? How did mud and stone develop into beings that can experience longing, regret, love, and compassion - beings that are aware of their own experience? Until recently, science offered few answers to these existential questions. Journey of the Mind is the first book to offer a unified account of the mind that explains how consciousness, language, the Self, and civilization emerged incrementally out of chaos.

An almost limitless archive of our history lies hidden inside our bodies, and this book traces the ancient story of Scotland from that scientific viewpoint. The mushrooming of genetic studies, of DNA analysis, is rewriting history in spectacular fashion. In Scotland: A Genetic Journey, Alistair Moffat explores the history that is printed on our genes, and in a remarkable new approach, uncovers the detail of where Scots are from, where they have journeyed, and who they are - and in so doing, vividly colors in a DNA map of Scotland.

Known as the ‘four horsemen’ of New Atheism, these four big thinkers of the 21st century met only once. Their electrifying examination of ideas on this remarkable occasion was intense and wide-ranging. Everything that was said as they agreed and disagreed with one another, interrogated ideas and exchanged insights - about religion and atheism, science and sense - speaks with urgency to our present age.

Preeminent paleoanthropologist Meave Leakey brings us along on her remarkable journey to reveal the diversity of our early pre-human ancestors and how past climate change drove their evolution. She offers a fresh account of our past, as recent breakthroughs have allowed new analysis of her team’s fossil findings and vastly expanded our understanding of our ancestors. Meave’s own personal story is replete with drama, from thrilling discoveries on the shores of Lake Turkana to run-ins with armed herders and every manner of wildlife, to raising her children....

An Olympic athlete. An award-winning novelist. A successful entrepreneur. All raised under one roof. What can we learn from those families whose children aim high and succeed, sometimes in widely varied fields? Just as important: What were the costs along the way, and what can we glean from their travails and triumphs? The acclaimed New York Times journalist Susan Dominus offers compelling profiles of six such families in search of the factors that led to their success—was it an inherited quality, a specific way of parenting, the influence of a sibling, or a twist of luck?

Maternal instinct - the all-consuming, utterly selfless love that mothers lavish on their children - has long been assumed to be an innate, indeed defining element of a woman's nature. But is it? In this provocative, groundbreaking audiobook, renowned anthropologist (and mother) Sarah Blaffer Hrdy shares a radical new vision of motherhood and its crucial role in human evolution. Hrdy strips away stereotypes and gender-biased myths to demonstrate that traditional views of maternal behavior are essentially wishful thinking codified as objective observation.
