We spend roughly a third of our lives in bed, but for millions of us, not all of that time is spent sleeping. We strive for eight hours per night, only to lie awake thanks to stress, our ever-present devices, a new baby, or that 4pm coffee you thought you needed. As sleep scientist and recovering insomniac Merijn van de Laar shows, we’re hardly the first to experience this. When homo sapiens evolved hundreds of thousands of years ago, when saber-toothed tigers were their biggest nighttime worry, wakefulness served to protect one’s tribe at night.

Over the past 20 years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.

For most of us, the story of mammal evolution starts after the asteroid impact that killed the dinosaurs, but over the last 20 years, scientists have uncovered new fossils and used new technologies that have upended this story. In Beasts Before Us, paleontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over 300 million years ago. They made the world theirs long before the rise of dinosaurs.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that Earth is around 4.6 billion years old, and the first four billion years of its development are known as the Precambrian period.

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.

In Origin Story, medical historian Howard Markel recounts the two-year period (1858 to 1860) of Darwin's writing of On the Origin of Species through its spectacular success and controversy. Simultaneously, Markel delves into the mysterious health symptoms Darwin developed, combing the literature to emerge with a cogent diagnosis of a case that has long fascinated medical historians.

No one wants to overeat. And certainly no one wants to overeat for years, become overweight, and end up with a high risk of diabetes or heart disease--yet two thirds of Americans do precisely that. Even though we know better, we often eat too much. Why does our behavior betray our own intentions to be lean and healthy? The problem, argues obesity and neuroscience researcher Stephan J. Guyenet, is not necessarily a lack of willpower or an incorrect understanding of what to eat.

«Nos encantaría descubrir que cada especie tiene un reloj biológico en sus células, porque, de existir ese reloj y si fuéramos capaces de dar con él, quizá pudiéramos pararlo y de ese modo volvernos eternos», le plantea Arsuaga a Millás en este libro en el que la ciencia se entrelaza con la literatura. El paleontólogo desvela aspectos esenciales de nuestra existencia al escritor, y se debate sobre la conveniencia de transmitir su visión azarosa de la vida a un Millás a dieta que descubre que la vejez es un país en el que todavía se siente extranjero.

Why do so many of us have trouble falling asleep? Why do our thoughts spin in wild directions after dark? More important: why do we dream? In this groundbreaking new book, investigative journalist and anthropologist Scott Carney sets out to discover how the sleeping world reverberates in the waking one. Unlock the power of the immune system at the same time you dig deeply into the source of creativity. Discover the evolutionary process that forges both memory and emotions.

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behavior evolve?

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.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

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.

Spontaneous generation of living organisms - life arising without progenitor or seed - was a common belief in the time of Aristotle. Over the next 2,000 years, support for spontaneous generation slowly retreated to its final stronghold: spontaneous formation of the first living organism.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.

Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be.

To better understand the inner workings of our bodies and to trace the origins of many of today's most common diseases, we have to turn to unexpected sources: worms, flies, and even fish.

In A Story of Us, they present this rich narrative and explain how the evolution of our genes relates to the evolution of our cultures. Newson and Richerson take listeners through seven stages of human evolution, beginning seven million years ago with the apes that were the ancestors of humans and today's chimps and bonobos. The story ends in the present day and offers a glimpse into the future.

Religious fundamentalists and biblical literalists present any number of arguments that attempt to disprove evolution. Those with a sympathetic ear often fail to critically examine these creationist claims, leading to an ill-informed public and, perhaps more troubling, ill-advised public policy. As Aron Ra makes clear, however, every single argument deployed by creationists in their attacks on evolution is founded on fundamental scientific, religious, and historical falsehoods - all of them.

While plenty of entertaining books have been written about the history of alcohol and other intoxicants, none have offered a comprehensive, convincing answer to the basic question of why humans want to get high in the first place. Drunk elegantly cuts through the tangle of urban legends and anecdotal impressions that surround our notions of intoxication to provide the first rigorous, scientifically grounded explanation for our love of alcohol.
