Evolutionary theory in the theme that binds together these essays on such seemingly disparate topics as the feeding habits of flamingos, flowers and snails that change from male to female and sometimes back again, and the extinction from baseball of the .400 hitter.

Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how.

In The Other Big Bang, the evolutionary and developmental biologist Eric S. Haag explores the two-billion-year history of sex, from the first organisms on Earth to contemporary humans.

Robert Ardrey guides the listener on a remarkable journey of discovery through 20 million years of man's prehistory: from the days when his ancestors first emerged from the forests of Africa during the benevolent warmth and rains of the Miocene, through the unremitting drought of the Pliocene and the dramatic climactic shifts of the Pleistocene, down to those few thousand years past when man emerged at last onto the stage of recorded history as a fully evolved hunting animal.

Charles Darwin was just 22 when he went on his first voyage around the world in 1831. Darwin's father at first refused to allow his young son to go on the voyage. Fortunately, his father relented, and Darwin's journal is now considered by many to be the greatest scientific travel narrative ever written.

The Evolution of Creationism is a compelling exploration of the enduring conflict between evolutionary science and creationist ideology. From the initial reactions to Darwin’s On the Origin of Species to the modern legal battles over science education, this book delves into the historical, cultural, and political forces shaping the debate. Through detailed analysis of key events—such as the Huxley-Wilberforce debate, the Scopes Trial, and contemporary Intelligent Design movements—this book exposes the shifting strategies of creationists and the scientific responses that have countered...

Tribalism is one of the most complex and ancient evolutionary forces; it gave us the capacity for cooperation and competition, and allowed us to navigate increasingly complex social landscapes. It is so powerful that it can predict our behavior even better than race, class, gender, or religion. But in our vast modern world, has this blessing become a curse? Our Tribal Future explores a central paradox of our species: how altruism, community, kindness, and genocide are all driven by the same core adaptation.

James T. Costa takes listeners on a journey from Darwin's youth and travels on the HMS Beagle to Down House, his bustling home of 40 years. We accompany Darwin in his myriad pursuits against the backdrop of his enduring marriage, chronic illness, grief at the loss of three children, and joy in scientific revelation. At each chapter's end, Costa shows how we, too, can investigate the wonders of nature at work, with directions on how to re-create Darwin's experiments.

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.

Are humans unwitting partners in evolution with psychedelic plants? Darwin’s Pharmacy shows they are by weaving the evolutionary theory of sexual selection and the study of rhetoric together with the science and literature of psychedelic drugs. Long suppressed as components of the human tool kit, psychedelic plants can be usefully modeled as “eloquence adjuncts” that intensify a crucial component of sexual selection in humans: discourse.

Today's generation is bombarded with theories about humankind and its origins. The danger for Christians lies in the wealth of misinformation and miscommunication about simple biblical truths such as: (1) How and when the world began, (2) Whether humans are unique or merely a happenstance of evolution, (3) The distinction between humankind and other living creatures, (4) The evolution of life on this planet, and (5) The spiritual dimensions of the human soul.

We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies, and television shows proliferate that attempt to answer this question and explore it. In Out There, Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer).

Why are conditions like autism, asthma, obesity, and allergies exploding at unprecedented rates? Why are we living longer, getting smarter, having far fewer kids? If Darwin were alive today, how would he explain this new world?

But the quest to unravel life's genesis is not just a story of big ideas. It is also a compelling human story, rich in personalities, conflicts, and surprising twists and turns. Along the way the journey takes in some of the greatest discoveries in modern biology, from evolution and cells to DNA and life's family tree. It is also a search whose end may finally be in sight. In The Genesis Quest, Michael Marshall shows how the quest to understand life's beginning is also a journey to discover the true nature of life, and by extension our place in the universe.

Our ability to think about the future is one of the most powerful tools at our disposal. In The Invention of Tomorrow, cognitive scientists Thomas Suddendorf, Jonathan Redshaw, and Adam Bulley argue that its emergence transformed humans from unremarkable primates to creatures that hold the destiny of the planet in their hands. Drawing on their own cutting-edge research, the authors break down the science of foresight, showing us where it comes from, how it works, and how it made our world.

In Wild Sex, Dr. Carin Bondar takes listeners on an enthralling tour of the animal kingdom as she explores the diverse world of sex in the wild. She looks at the evolution of sexual organs (and how they've shaped social hierarchies), tactics of seduction, and the mechanics of sex. She investigates a wide range of topics, from whether animals experience pleasure from sex to what happens when females hold the reproductive power.

Vor 100.000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70.000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens.

Darwin considered humans one part of the web of life, not the apex of a natural hierarchy. Yet today many maintain that we are the most intelligent, virtuous, successful species that ever lived. This flawed thinking enables us to exploit the earth towards our own exclusive ends, throwing us into a perilous planetary imbalance. But is this view and way of life inevitable? The Arrogant Ape shows that human exceptionalism is an ideology that relies more on human culture than our biology, more on delusion and faith than on evidence.

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.

Si la historia de la Tierra se redujera a un año, nuestra especie surgiría en los últimos treinta minutos. Pero la vida ha existido durante 3.700 millones de años, la mayor parte de la historia de nuestro planeta y más de una cuarta parte de la edad del universo. ¿Qué hicieron esos organismos durante todo este tiempo?
