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 10 riveting episodes, paleoanthropologist Elen Feuerriegel takes you on an unrivaled tour of the human fossil record in search of the biological and behavioral underpinnings of our very “humanness”.

Who are we, and how did we get here? These are two of the most fundamental and far-reaching questions facing scientists and cosmologists alike and have rested at the center of human intellectual endeavor since its beginning. They are questions that stretch across numerous disciplines. Philosophy, theology, evolutionary biology, and mathematics are just some of the fields looking to explain the emergence of human life.

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.

In a tour de force of science and logic, the best-selling author of Darwin's Black Box combines genetics, laboratory results, and mathematics to prove, once and for all, that the universe and life on Earth are designed.

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.

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.

In The Ancestor's Tale, evolutionary biologist Richard Dawkins offers a masterwork: an exhilarating reverse tour through evolution, from present-day humans back to the microbial beginnings of life four billion years ago. Throughout the journey, Dawkins spins entertaining, insightful stories and sheds light on topics such as speciation, sexual selection, and extinction. The Ancestor's Tale is at once an essential education in evolutionary theory and riveting in its telling.

Why is the genome of a salamander 40 times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution - and human society - really works.

«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.

The New York Times best-selling author of Darwin’s Doubt presents groundbreaking scientific evidence of the existence of God, based on breakthroughs in physics, cosmology, and biology.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How?

As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference.
It’s a frightening prospect, as each of the Earth’s past major disasters—from meteor strikes to bombardment by cosmic radiation—resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation—humans have, more than once, narrowly avoided extinction just
during the last million years—but every single time a few creatures survived, evolving to adapt to the harshest of conditions.
This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death.
Newitz’s remarkable and fascinating journey through the science of mass extinctions is a powerful argument about human ingenuity and our ability to change. In a world populated by doomsday preppers and media commentators obsessively forecasting our demise, Scatter, Adapt, and Remember is a compelling voice of hope. It leads us away from apocalyptic thinking into a future where we live to build a better world—on this planet and perhaps on others. Readers of this book will be equipped scientifically, intellectually, and emotionally to face whatever the future holds.

"El cerebro vive en un cuarto oscuro". "Tal es el gran misterio al que nos enfrentamos", afirma Arsuaga en este libro en el que el sapiens y el neandertal afrontan el mayor desafío de su proyecto en común, el más complejo, el que supone abrir una puerta a lo ignorado. Vivimos con la paradoja de que, pese a los avances de la neurociencia en los últimos años, el cerebro, que rige nuestra conexión con el mundo, continúa siendo el gran desconocido.

How did life begin? It is perhaps the most important question science has ever asked. Over the centuries, the search for an answer has been entwined with some of science's most revolutionary advances, including van Leeuwenhoek's microscope, Darwin's theory of evolution, and Crick and Watson's unveiling of DNA.

What would it be like to visit the ancient landscapes of the past? To experience the Jurassic or Cambrian worlds, to wander among these other lands, as creatures extinct for millions of years roam? In this mesmerizing debut, award-winning palaeontologist Thomas Halliday gives us a breath-taking up-close encounter with worlds that are normally unimaginably distant.

De la mano de uno de los historiadores más interesantes de la actualidad, he aquí la fascinante interpretación de Yuval Noah Harari sobre la historia de la humanidad. Bestseller nacional e internacional, este libro explora las formas en que la biología y la historia nos han definido y han mejorado nuestra comprensión de lo que significa ser "humano".

The Voyage of the Beagle - or, to give it its full title, Journal of researches into the Natural History and Geology of the Countries visited during the Voyage round the World of H.M.S. Beagle under command of Captain FitzRoy, R.N. - is much more than merely an account of Darwin's scientific observations in his 1831 - 36 travels across the globe: it is fine travel writing in its own right.

No hay ningún plan de alimentación funcional para todo el mundo: lo que a unos les sienta bien, a otros puede hacerles daño. ¿Cómo se explica? Por el código genético, que es absolutamente único en cada persona.

How did humans come to be who we are? In his marvelous, eccentric, and widely lauded book Being a Beast, legal scholar, veterinary surgeon, and naturalist extraordinaire Charles Foster set out to understand the consciousness of animal species by living as a badger, otter, fox, deer, and swift. Now, he inhabits three crucial periods of human development to understand the consciousness of perhaps the strangest animal of all—the human being.
