Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

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.

From the very beginning, life on Earth has been defined by war. Today, those first wars continue to be fought around and literally inside us, influencing our individual behavior and that of civilization as a whole. War between populations - whether between different species or between rival groups of humans - is seen as an inevitable part of the evolutionary process. The popular concept of "the survival of the fittest" explains and often excuses these actions.

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.

Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?

In this classic volume, Peter Matthiessen exquisitely combines nature and travel writing to bring East Africa to vivid life. He skillfully and magically portrays the sights, scenes, and people he observed firsthand in several trips over the course of a dozen years: the daily lives of herdsmen and hunter-gatherers; the drama of the predator kills; the hundreds of exotic animals; the breathtaking landscapes; the area's turbulent natural, political, and social histories; and more.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

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.

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

Who are we, and how did we get here? These are two of the most fundamental and far-reaching questions facing scientists and cosmologists alike and have rested at the center of human intellectual endeavor since its beginning. They are questions that stretch across numerous disciplines. Philosophy, theology, evolutionary biology, and mathematics are just some of the fields looking to explain the emergence of human life.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

Engrossing and captivating, Editing Humanity takes listeners inside the fascinating world of a new gene editing technology called CRISPR, a high-powered genetic toolkit that enables scientists to not only engineer but to edit the DNA of any organism down to the individual building blocks of the genetic code. Davies introduces listeners to arguably the most profound scientific breakthrough of our time. He tracks the scientists on the front lines of its research to the patients whose powerful stories bring the narrative movingly to human scale.

In this engaging exploration, archaeologist Ian Hodder departs from the two prevailing modes of thought about human evolution: the older idea of constant advancement toward a civilized ideal and the newer one of a directionless process of natural selection. Instead, he proposes a theory of human evolution and history based on "entanglement," the ever-increasing mutual dependency between humans and things.

In his provocative new book, evolutionary biologist Jerry A. Coyne lays out in clear, dispassionate detail why the toolkit of science, based on reason and empirical study, is reliable, while that of religion - including faith, dogma, and revelation - leads to incorrect, untestable, or conflicting conclusions.

Dr. Carl Sagan takes us on a great adventure, offering his vivid and startling insight into the brain of man and beast, the origin of human intelligence, the function of our most haunting legends - and their amazing links to recent discoveries.

We’re constantly seeking answers to these fundamental human questions, and now, science has the answers. The foods we enjoy, the people we love, the emotions we feel, and the beliefs we hold can all be traced back to our DNA, germs, and environment. This witty, colloquial book is popular science at its best, describing in everyday language how genetics, epigenetics, microbiology, and psychology work together to influence our personality and actions.
