Hace 13.000 años la evolución de las distintas sociedades humanas comenzó a tomar rumbos diferentes. La temprana domesticación de animales y el cultivo de plantas silvestres en el Creciente Fértil, China, Mesoamérica y otras zonas geográficas otorgó una ventaja inicial a sus habitantes. Sin embargo, los orígenes localizados de la agricultura y la ganadería son solo una parte de la explicación de los diferentes destinos. Las sociedades que superaron esta fase de cazadores-recolectores se encontraron con más probabilidades de desarrollo, supervivencia y poder bélico.

“There is no good reason why human societies should not be described and explained with the same precision and success as the rest of nature.” Thus argues evolutionary psychologist Pascal Boyer in this uniquely innovative book. Integrating recent insights from evolutionary biology, genetics, psychology, economics, and other fields, Boyer offers precise models of why humans engage in social behaviors such as forming families, tribes, and nations, or creating gender roles.

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.

At once a spirited defense of Darwinian explanations of biology and an elegant primer on evolution for the general listener, What Evolution Is poses the questions at the heart of evolutionary theory and considers how our improved understanding of evolution has affected the viewpoints and values of modern man.

What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

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.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

In The Genome Odyssey, Dr. Euan Ashley, Stanford professor of medicine and genetics, brings the breakthroughs of precision medicine to vivid life through the real diagnostic journeys of his patients and the tireless efforts of his fellow doctors and scientists as they hunt to prevent, predict, and beat disease.

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.

Darwin's theory of evolution is accepted by most educated Americans as simple fact. This easy acceptance, however, hides from us the many ways in which evolution - as an idea - shapes our thinking about a great many things. What if this idea is wrong? What if "evolution" is just a word that covers up scientific ignorance of how the wonders of the living world could have been created? Berkeley law professor Phillip Johnson looks at the evidence for Darwinistic evolution the way a lawyer would - with a cold dispassionate eye for logic and proof.

The Galapagos were once known to the sailors and pirates who encountered them as Las Encantadas: the enchanted islands, home to exotic creatures and dramatic volcanic scenery. In The Galapagos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its evolution from deserted wilderness to scientific resource (made famous by Charles Darwin) and global ecotourism hot spot.

Among the estimated 100 billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of "becoming" in each case. Since Newton, we have turned to physics to assess reality. But physics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science--and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. A new preface shows how this witty, playful, and daring book has revolutionized our understanding of sexuality.

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.

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

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.

This audiobook takes you on an exciting journey into the past to uncover the story of the Denisovans. Hidden deep in the Denisova Cave in Siberia, their remains went unnoticed for centuries. But when scientists discovered them, it changed what we knew about human history.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

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.
