Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

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.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

All of life is profoundly shaped by the daily, monthly, and yearly cycles of our planet, and all creatures have internal timekeeping systems that rely on cues from the surrounding environment. With modern technology, we are changing our environments—and by proxy, the ecosystems around us—to override these innate rhythms of life. But at what cost? Life in Sync reveals how Earth’s rotations shape our biology, what human sleep cycles looked like before the advent of artificial light, and why technology can’t free us from the constraints of our circadian clocks.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

This audiobook narrated by Christopher Ragland describes the revolution in science that is transforming our understanding of extinct life.

We're living through a golden age of paleontological research that, in the last couple of decades, has radically changed our understanding of dinosaurs. Through candid interviews with the world's top paleontologists, Professor Ben Garrod reveals new dinosaur facts from cutting edge research into the greatest animals ever to walk the planet.

In this entertaining book, Donald R. Prothero explores the astonishing connections between climate and life through the ages, telling the remarkable stories of the scientists who made crucial discoveries. Journeying through the intertwined evolution of climate and life, he tackles questions such as: Why do we have phytoplankton to thank for the air we breathe? What kind of climate was necessary for the rise of the dinosaurs-or the mammals, their successors? When and how have climatic changes caused mass extinctions?

In the 19th and early 20th centuries, North American and European governments generously funded the discoveries of such famous paleontologists and geologists as Henry de la Beche, William Buckland, Richard Owen, Thomas Hawkins, Edward Drinker Cope, O. C. Marsh, and Charles W. Gilmore. In this book, Jane Davidson explores the motivation behind this rush to fund exploration, arguing that eagerness to discover strategic resources like coal deposits was further fueled by patrons who had a genuine passion for paleontology and the fascinating creatures that were being unearthed.

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.

At stake in the "Science Wars" that have raged in academe and in the media is nothing less than the standing of science in our culture. One side argues that science is a "social construct," that it does not discover facts about the world, but rather constructs artifacts disguised as objective truths. This view threatens the authority of science and rejects science's claims to objectivity, rationality, and disinterested inquiry. Drawing Out Leviathan examines this argument in the light of some major debates about dinosaurs.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.

This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies.

In the middle of New York City lies a neighborhood where all secrets are valuable, all assets are liquid, and all deals are sealed with a blessing rather than a contract. Welcome to the diamond district. Ninety percent of all diamonds that enter America pass through these few blocks, but the inner workings of this mysterious world are known only to the people who inhabit it.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?
