Books about the origins of humanity dominate bestseller lists, while national newspapers present breathless accounts of new archaeological findings and speculate about what those findings tell us about our earliest ancestors. We are obsessed with prehistory—and, in this respect, our current era is no different from any other in the last three hundred years. In this coruscating work, acclaimed historian Stefanos Geroulanos demonstrates how claims about the earliest humans not only shaped Western intellectual culture, but gave rise to our modern world.

A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century. In 2013, Lee Berger, a National Geographic explorer-in-residence, heard of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators - men and women small and adventurous enough to be able to squeeze through eight-inch tunnels to reach a sunless cave forty feet underground. It worked.

The study of human evolution is advancing rapidly. Newly discovered fossil evidence is adding ever more pieces to the puzzle of our past, while revolutionary technological advances in the study of ancient DNA are completely reshaping theories of early human populations and migrations. In this Very Short Introduction, Bernard Wood traces the history of paleoanthropology from its beginnings in the 18th century to the very latest fossil finds.

The Imperiled Ocean by ocean journalist Laura Trethewey is a deeply reported work of narrative journalism that follows people as they head out to sea. What they discover holds inspiring and dire implications for the life of the ocean - and for all of us back on land.

What gives the human brain the creative ability that defines us all as individuals? Although the silicon version is hard on its heels, the brain remains the most remarkable computer in existence. Leading us through cognitive theory, neuroscience and Darwinian evolution with his trademark wit and wisdom, Michael Corballis explains what we know - and don't know - about our minds. How do we know if we’re really the top dogs in brain power?

The COVID-19 pandemic has brought forth global anxiety about linkages between the environment and society at a fundamental structural level. Earthly Order: How Natural Laws Define Human Life provides an accessible exposition of the latest foundational knowledge on how natural and social systems science can inform planetary crises. Humanity has either tried to conquer or capitulate to natural order, whereas we should be seeking to understand latent structures and patterns that permeate all systems and develop an "earthly order," that is socially functional and sustainable.

Africa has long been considered the cradle of life - where life and humans evolved - but somewhere west of Munich, Germany, paleoclimatologist and paleontologist Madelaine Böhme and her team make a discovery that is beyond anything they ever imagined: the 12-million-year-old bones of an ancient ape - Danuvius guggenmos - which makes headlines around the world and defies prevailing theories of human history and where human life began.

Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

“[A] winningly obsessive history of our relationship with underground places” (The Guardian), from sacred caves and derelict subway stations to nuclear bunkers and ancient underground cities—an exploration of the history, science, architecture, and mythology of the worlds beneath our feet...

Ranging from prehistory to the 21st century, The Great Sea is above all the history of human interaction across a region that has brought together many of the great civilizations of antiquity as well as the rival empires of medieval and modern times.

Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted audiobook offers a new, holistic way of thinking about energy and water - a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure continuing sustainability.

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.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?
