Our world has ended five times: It has been broiled, frozen, poison gassed, smothered, and pelted by asteroids. In The Ends of the World, Peter Brannen dives into deep time, exploring Earth's past dead ends, and in the process offers us a glimpse of our possible future. Many scientists now believe that the climate shifts of the 21st century have analogs in these five extinctions.

This adventure in science and imagination, which the Medical Tribune said might herald "a Copernican revolution for the life sciences", leads the listener through unexplored jungles and uncharted aspects of mind to the heart of knowledge. In a first-person narrative of scientific discovery that opens new perspectives on biology, anthropology, and the limits of rationalism, The Cosmic Serpent reveals how startlingly different the world around us appears when we open our minds to it.

Mary Anning was only 12 years old when, in 1811, she discovered the first dinosaur skeleton - of an ichthyosaur - while fossil hunting on the cliffs of Lyme Regis, England. Until Mary's incredible discovery, it was widely believed that animals did not become extinct.

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.

Sound interesting? The author thinks so too! Listen to Bully for Brontosaurus and learn about natural history.

Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be.

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.

To better understand the inner workings of our bodies and to trace the origins of many of today's most common diseases, we have to turn to unexpected sources: worms, flies, and even fish.

Feathers are an evolutionary marvel: Aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?

If the history of the Earth were compressed down to a year, our species would arise in the last thirty minutes or so of the final hour. But life itself is not such a late arrival: It has existed on Earth for something like 3.7 billion years—most of our planet’s history and over a quarter of the age of the universe (as far as we can tell). What have these organisms—bacteria, animals, plants, and the rest—done in all this time? In Living on Earth, the philosopher Peter Godfrey-Smith proposes a new way of understanding how the actions of living beings have shaped our planet.

Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.

The idea of a missing link between humanity and our animal ancestors predates evolution and popular science and actually has religious roots in the deist concept of the Great Chain of Being. Yet, the metaphor has lodged itself in the contemporary imagination, and new fossil discoveries are often hailed in headlines as revealing the elusive transitional step, the moment when we stopped being "animal" and started being "human". In The Accidental Species, Henry Gee, longtime paleontology editor at Nature, takes aim at this misleading notion.

With stories that entertain as much as they inform, renowned evolutionist David Sloan Wilson outlines the basic principles of evolution and shows how, when properly understood, they can illuminate the length and breadth of creation, from the origin of life to the nature of religion.

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.

Who are we? How do scientists define Homo sapiens, and how does our species differ from the extinct hominins that came before us? In this accessible account palaeoarchaeologist Paul Pettitt shows how the latest scientific advances, especially in genetics, are revolutionizing our understanding of human evolution. Pettitt reveals the extraordinary story of how our ancestors adapted to unforgiving and relentlessly changing climates, leading to remarkable innovations in art, technology, and society that we are only now beginning to comprehend.

Why do so many of us have trouble falling asleep? Why do our thoughts spin in wild directions after dark? More important: why do we dream? In this groundbreaking new book, investigative journalist and anthropologist Scott Carney sets out to discover how the sleeping world reverberates in the waking one. Unlock the power of the immune system at the same time you dig deeply into the source of creativity. Discover the evolutionary process that forges both memory and emotions.

The entirety of the human brain’s 4-billion-year story can be summarised as the culmination of five evolutionary breakthroughs, starting from the very first brains, all the way to the modern human brains. Each breakthrough emerged from new sets of brain modifications, and equipped animals with a new suite of intellectual faculties. These five breakthroughs are the organising map to this book, and they make up our itinerary for our adventure back in time. Each breakthrough also has fascinating corollaries to breakthroughs in AI.

Charles Darwin’s theory of evolution now forms the basis for all the life sciences, but it ignited widespread controversy upon its 1859 publication. The idea that humans and animals might have evolved from a common source came as a shock to readers at the time, and people struggle with the implications of Darwin’s theory to this day. But Darwin foresaw this resistance and argued his case with extensive examples and rigorous logic - and his theory continues to push us toward a deeper understanding of life on Earth.

What is life? In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect.

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs - they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken - imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time.
