How four tools enabled humanity to control its destiny What enabled us to go from simple stone tools to smartphones? How did bands of hunter-gatherers evolve into multinational empires? Listeners of Sapiens will say a cognitive revolution - a dramatic evolutionary change that altered our brains, turning primitive humans into modern ones - caused a cultural explosion. In Transcendence, Gaia Vince argues instead that modern humans are the product of a nuanced coevolution of our genes, environment, and culture that goes back into deep time.

We harbor roughly the same number of microbes as we have cells. This complex ecosystem is crucial to our health, affecting many processes including immunity, child development, and bone density regulation. Research in this area has exploded, and in this audiobook, we highlight some of the most exciting work on how the microbiome develops, its influence on brain and behavior, and implications in both contributing to and treating various disorders.

"It's the animal in us," we often hear when we've been bad. But why not when we're good? Primates and Philosophers tackles this question by exploring the biological foundations of one of humanity's most valued traits: morality.In this provocative book, primatologist Frans de Waal argues that modern-day evolutionary biology takes far too dim a view of the natural world, emphasizing our "selfish" genes.

Over the past 20 years, Evolutionary Biologist Herman Pontzer has conducted ground-breaking studies across a range of settings, including pioneering fieldwork with Hadza hunter-gatherers in northern Tanzania. This book draws on his eye-opening research to show how, contrary to received wisdom, exercise does not increase our metabolism. Instead, we burn calories within a very narrow range: nearly 3,000 calories per day, no matter our activity level.

An estimated 10 percent of Americans are implanted with medical devices - like pacemakers, artificial hips, cardiac stents, etc. The overwhelming majority of high-risk implanted devices have never undergone a single clinical trial. The FDA lets device manufacturers decide whether to report serious complications or deaths that may have been caused by their products. Here, award-winning journalist Jeanne Lenzer brings these horrifying statistics to life through the story of one working-class man who, after his "cure" nearly kills him, ends up in a battle for justice.

Despite advances in health care, infectious microbes continue to be a formidable adversary to scientists and doctors. Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.

For decades Richard Dawkins has been the world's most brilliant scientific communicator, consistently illuminating the wonders of nature and attacking faulty logic. Science in the Soul brings together 42 essays, polemics, and paeans - culled from personal papers, newspapers, lectures, and online salons - all written with Dawkins' characteristic erudition, remorseless wit, and unjaded awe of the natural world.

Until recently, microglia were thought to be merely the brain’s housekeepers, helpfully removing damaged cells. But a recent groundbreaking discovery revealed them to be capable of terrifying Jekyll and Hyde behavior. When triggered - and anything that stirs up the immune system in the body can activate microglia - they can morph into destroyers, impacting a wide range of issues from memory problems and anxiety to depression and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers.

We are living through the most prosperous age in all of human history, yet we are listless, divided, and miserable. Wealth and comfort are unparalleled, but our political landscape is unmoored, and rates of suicide, lone­liness, and chronic illness continue to skyrocket. How do we explain the gap between these truths? And how should we respond? For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our troubles is clear: The accelerat­ing rate of change in the modern world has outstripped the capacity of our brains and bodies to adapt.

Humanity can make short work of the oceans' creatures. In 1741, hungry explorers discovered herds of Steller's sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It's a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail.

A riveting investigation of the myriad ways that parasites control how other creatures - including humans - think, feel, and act. These tiny organisms can live only inside another animal, and, as McAuliffe reveals, they have many evolutionary motives for manipulating their host's behavior. Far more often than appreciated, these puppeteers orchestrate the interplay between predator and prey.

Perfect for fans of horror and science alike, Rise of the Zombie Bugs offers a chilling yet enlightening look at the hidden world of parasites. It's a must-listen for anyone curious about the true terrors lurking in nature's undergrowth and the unnerving beauty of evolution's darker side.

As one of the most beautiful and intriguing birds found in nature, hummingbirds fascinate people around the world. The lightest birds in the sky, hummingbirds are capable of incredible feats, such as flying backwards, diving at speeds of 61 MPH, and beating their wings more than 60 times a second. Miraculous creatures, they are also incredibly vulnerable when they first emerge from their eggs. That’s where Brenda Sherburn comes in. With tenderness and patience, she rescues abandoned hummingbirds and nurses them back to health until they can fly away and live in the wild.

Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and - borrowing a famous phrase from philosopher Jeremy Bentham - the nonsense on stilts.

Sy Montgomery's popular 2011 Orion magazine piece, "Deep Intellect", about her friendship with a sensitive, sweet-natured octopus named Athena and the grief she felt at her death, went viral, indicating the widespread fascination with these mysterious, almost alien-like creatures. Since then Sy has practiced true immersion journalism, from New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, pursuing these wild, solitary shape-shifters.

Lewis Thomas has been compared to a philosopher who uses the language of biology. His fascinating observations on the quirkiness of the world's infinite creations causes the listener to ponder the workings of the cosmos through the most microscopic of life forms.

The latest and most bitterly contested battle in the culture war is the controversy over Darwin and intelligent design. But much of what you've heard about it is wrong. Jonathan Wells, a battle-hardened veteran with doctorates in biology and theology, sets the record straight.

Over billions of years, ancient fish evolved to walk on land, reptiles transformed into birds that fly, and apelike primates evolved into humans that walk on two legs, talk, and write. For more than a century, paleontologists have traveled the globe to find fossils that show how such changes have happened.

This is the only book that tells both sides of the story of germs: that they are critically important for our health and that the dangers of emerging pathogens continue to wreak havoc in our bodies and around the world.

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.
