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.

Once, we humans could only observe evolution. Suddenly, we had conquered it. And yet, in Life as We Made It, evolutionary biologist Beth Shapiro argues that - despite how amazing our new technologies are - our ability to alter the course of evolution isn’t new. What is new is that where once we shaped evolution through brute force, we can now do it as artisans. That power comes not a moment too soon. If we are going to survive in the next few centuries, we must revise the book of life.

Having worked on numerous high-profile genetic investigations, including one focused on the famed Iceman of the Italian Alps, Bryan Sykes has become a premier authority on human genetics. In DNA USA, Sykes examines the unique fabric of the population of the United States - one of the world’s most genetically variegated countries. His fascinating discoveries offer new insights into the biological profile of the great melting pot.

"Probability Zero represents the most rigorous mathematical challenge to Neo-Darwinian theory ever published. Period." —Frank J. Tipler, Professor of Mathematical Physics, Tulane University THE BONFIRE OF MODERN BIOLOGY For over a century, the Theory of Evolution by Natural Selection has served as the secular creation myth of the modern world. It has been hailed as the origin of the species, the foundation of modern biology, the cornerstone of the Enlightenment, and the universal acid that redefined Man's place in the universe. But after 150 years of storytelling, the scientific myths ...

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

Human life, and how we came to be, is one of the greatest scientific and philosophical questions of our time. This compact and accessible book presents a modern view of human evolution. Written by a leading authority, it lucidly and engagingly explains not only the evolutionary process, but the technologies currently used to unravel the evolutionary past and emergence of Homo sapiens.

The authors of the New York Times bestseller Super Brain present a bold new understanding of our genes and how simple changes in lifestyle can boost genetic activity. The leap into "radical well-being" is a promise waiting to be fulfilled. "You are not simply the sum total of...

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

The emerging field of evolutionary psychology remains controversial, perhaps especially among Christians. Yet according to Justin Barrett and Pamela Ebstyne King, it can be a powerful tool for understanding human nature and our distinctively human purpose. Thriving with Stone Age Minds provides an introduction to evolutionary psychology, explaining key concepts like hyper-sociality, information gathering, and self-control.

Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.

NEW YORK TIMES BESTSELLER The legendary biologist and bestselling author mounts a timely and passionate defense of science and clear thinking with this career-spanning collection of essays, including twenty pieces published in the United States for the first time. For decades, Richard...

DNA is the genetic material that defines us as individuals. Over the last two decades, it has emerged as a powerful tool for solving crimes and determining guilt and innocence. But, very recently, an important new aspect of DNA has been revealed: it contains a detailed record of evolution. That is, DNA is a living chronicle of how the marvelous creatures that inhabit our planet have adapted to its many environments, from the freezing waters of the Antarctic to the lush canopy of the rain forest.

Almost daily, headlines announce newly discovered links between cancers and their genetic causes. Science journalist Jessica Wapner vividly relates the backstory behind those headlines, reconstructing the crucial breakthroughs, explaining the science behind them, and giving due to the dozens of researchers, doctors, and patients whose curiosity and determination restored the promise of a future to the more than 50,000 people diagnosed each year with chronic myeloid leukemia (CML).

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 serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

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.

As we approach a great turning point in history when technology is poised to redefine what it means to be human, The Fourth Age offers fascinating insight into AI, robotics, and their extraordinary implications for our species. “If you only read just one book about the AI revolution, make it...

Being human entails an astonishingly complex interplay of biology and culture, and while there are important differences between women and men, there is a lot more variation and overlap than we may realize. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed.

On his popular science blog, Pharyngula, PZ Myers has entertained millions of fans with his infectious love of evolutionary science and his equally infectious disdain for creationism, biblical literalism, intelligent design theory, and other products of godly illogic. This funny and fearless book collects and expands on some of his most popular writings, giving the religious fanaticism of our times the gleeful disrespect it deserves by skewering the apocalyptic fantasies, magical thinking, hypocrisies, and pseudoscientific theories advanced by religious fundamentalists of all stripes.

In Regenesis, George Church and science writer Ed Regis explore the possibilities of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies - far from the out-of-control nightmare depicted in science fiction - have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span.
