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. Now two pioneering scientists draw on their years of experience in paleontology, biology, chemistry, and astrobiology to deliver an eye-opening narrative using a generation’s worth of insights culled from new research.

When Charles Darwin finished The Origin of Species, he thought that he had explained every clue but one. Though his theory could explain many facts, Darwin knew that there was a significant event in the history of life that his theory did not explain. During this event, the "Cambrian explosion", many animals suddenly appeared in the fossil record without apparent ancestors in earlier layers of rock. In Darwin's Doubt, Stephen C. Meyer tells the story of the mystery surrounding this explosion of animal life.

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.

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.

In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. Lead researcher Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so. Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid.

Epigenetics is the science of living DNA, charting the chemical pathways that spur DNA into action by turning genes on and off. While the Human Genome Project of the early 2000s was hailed as the key to understanding human heredity and disease, that historic effort was just the beginning. It has taken epigenetics to fill in the picture, explaining how the fixed code of our genome is implemented in countless living processes.

Genome unravels the secrets of human nature without the usual reams of technical jargon. It shows outstanding breakthroughs in gene research, how we've gone from knowing almost nothing to knowing almost everything, and how our genes reveal more about our past, our evolution, and even our minds. Every important event in human history is written into our genes, whether it happened four billion or a few hundred years ago. All you need to know is where to look.

Throughout history, people have sought to reduce suffering, eliminate disease and enhance desirable qualities in their children. In the Victorian era eugenics, a full-blooded attempt to impose control over unruly biology, began to grow among the powerful and quickly spread to dozens of countries around the world. But these ideas are not merely historical: today, with new gene editing techniques, conversations are happening about tinkering with the DNA of our unborn children to make them smarter, fitter, stronger.

The scuba-diving philosopher and best-selling author of Other Minds explores the origins of animal consciousness. 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 flower-like worms, whose rooted bodies and intricate geometry are more reminiscent of plant life than anything recognisably animal. Yet these creatures are our cousins.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.

Nessa Carey’s The Epigenetics Revolution looks at how modern biology is rewriting our understanding of genetics, disease and inheritance....

What happens when your family tells you one thing, but a DNA test tells you another? Georgina Lawton grew up in a loving family but she didn’t look like anyone else. She has dark eyes, curly hair and brown skin. Both her parents were white. Georgina took a DNA test. The results changed her life forever. With millions around the world using 'do-it-yourself' DNA testing kits, Georgina follows the stories of those learning to live with the results.

Vor 100.000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70.000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens.

El ingenio de Millás y la sabiduría de Arsuaga unidos para contar la vida como la mejor de las historias.

The Martians explores the CIA's top-secret search for the Martians, multiple photos of strange anomalies, and the latest revelations about the environment and water on Mars. And most tantalizing of all: Did an ailing Martian race come to Earth in past eons and were they confused with gods? The questions concerning life on Mars - then and now - are many. The answers are astounding.

Riley Black brings us back in time to prehistoric seas, swamps, forests, and savannas where critical moments in plant evolution unfolded. Each chapter stars plants and animals alike, underscoring how the interactions between species have helped shape the world we call home. As the chapters move upwards in time, Black guides listeners along the burgeoning trunk of the Tree of Life, stopping to appreciate branches of an evolutionary story that links the world we know with one we can only just perceive now through the silent stone, from ancient roots to the present.

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.

After seeing his own cells used to grow clumps of new neurons - essentially mini-brains - Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves.

Carl Zimmer investigates one of the biggest questions of all: what is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilised egg is a living person, for example, and when we ought to declare a person legally dead.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.
