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.

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.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

Charles Darwin's foremost biographer, Janet Browne, delivers a vivid and accessible introduction to the book that permanently altered our understanding of what it is to be human. A sensation on its publication in 1859, The Origin of the Species profoundly shocked Victorian readers by calling into question the belief in a Creator with its description of evolution through natural selection. And Darwin's seminal work is nearly as controversial today.

We are on the cusp of a major transformation in healthcare—yet few people know it. At top hospitals and a few innovative health-tech startups, scientists are working closely with patients to dramatically extend their "healthspan"—the number of healthy years before disease sets in. In The Age of Scientific Wellness, two visionary leaders of this revolution in health take us on a thrilling journey to this new frontier of medicine.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.

How did human minds become so different from those of other animals? What accounts for our capacity to understand the way the physical world works, to think ourselves into the minds of others, to gossip, read, tell stories about the past, and imagine the future? These questions are not new: they have been debated by philosophers, psychologists, anthropologists, evolutionists, and neurobiologists over the course of centuries. One explanation widely accepted today is that humans have special cognitive instincts.

Biogeography is the study of geographic variation in all characteristics of life - ranging from genetic, morphological, and behavioral variation among regional populations of a species, to geographic trends in diversity of entire communities across our planet's surface. From the ancient hunters and gatherers to the earliest naturalists, Charles Darwin, Alfred Russel Wallace, and scientists today, the search for patterns in life has provided insights that proved invaluable for understanding the natural world.

With rapid advances in genomic technologies, genetic testing has become a key part of both clinical practice and research. Scientists are constantly discovering more about how genetics plays a role in health and disease, and healthcare providers are using this information to more accurately identify their patients' particular medical needs. Genetic information is also increasingly being used for a wide range of non-clinical purposes, such as exploring one's ancestry.

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.

Resistance to malaria. Blue eyes. Lactose tolerance. What do all of these traits have in common? Every one of them has emerged in the last 10,000 years.

In The Genealogical Adam and Eve, S. Joshua Swamidass tests a scientific hypothesis: What if the traditional account is somehow true, with the origins of Adam and Eve taking place alongside evolution? Building on well-established but overlooked science, Swamidass explains how it's possible for Adam and Eve to be rightly identified as the ancestors of everyone.

Life innovates constantly, producing perfectly adapted species—but there's a catch. Many animals and plants eke out seemingly unremarkable lives. Passive, constrained, modest, threatened. Then, in a blink of evolutionary time, they flourish spectacularly. Once we start to look, these 'sleeping beauties' crop up everywhere. But why? Looking at the book of life, from apex predators to keystone crops, and informed by his own cutting-edge experiments, renowned scientist Andreas Wagner demonstrates that innovations can come frequently and cheaply to nature, well before they are needed.

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species.

For many of us, the great scientific discoveries of the modern age—the Big Bang, evolution, quantum physics, relativity—point to an existence that is bleak, devoid of meaning, pointless. But in The Sacred Depths of Nature, eminent biologist Ursula Goodenough shows us that the scientific world view need not be a source of despair. Indeed, it can be a wellspring of solace and hope. This volume reconciles the modern scientific understanding of reality with our timeless spiritual yearnings for reverence and continuity.

Does human life have any meaning? Does the question even make sense today? For centuries, the question of the meaning or purpose of human life was assumed by scholars and theologians to have a religious answer: Life has meaning because humans were made in the image of a good god. In the 19th century, however, Charles Darwin's theory of evolution changed everything - and the human organism was seen to be more machine than spirit.

For all that science knows about the living world, notes David P. Barash, there are even more things we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

This momentous biography tells the story of the Huxleys: the Victorian natural historian T. H. Huxley ("Darwin's Bulldog") and his grandson, the scientist, conservationist, and zoologist Julian Huxley.

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.
