The burgeoning new science of epigenetics offers a cornucopia of insights - some comforting, some frightening. For example, the male fetus may be especially vulnerable to certain common chemicals in our environment, in ways that damage not only his own sperm but also the sperm of his sons. And it’s epigenetics that causes identical twins to vary widely in their susceptibility to dementia and cancer. But here’s the good news: unlike mutations, epigenetic effects are reversible. Indeed, epigenetic engineering is the future of medicine.

Charles Darwin's foremost biographer, Janet Browne, delivers a vivid and accessible introduction to the book that permanently altered our understanding of what it is to be human. A sensation on its publication in 1859, The Origin of the Species profoundly shocked Victorian readers by calling into question the belief in a Creator with its description of evolution through natural selection. And Darwin's seminal work is nearly as controversial today.

Each of us began life as a single cell. From this humble origin, we embarked on a risky journey fraught with opportunities for disaster. Yet, amazingly, we reached our destination intact, emerging as dazzlingly complex, exquisitely engineered assemblages of trillions of cells. This metamorphosis constitutes one of nature's most spectacular yet commonplace magic tricks—and one of its most coveted secrets. In From One Cell, physician and researcher Ben Stanger offers a glimpse into what scientists are discovering about how life and the body take shape.

The extraordinary Siddhartha Mukherjee has written a biography of the gene as deft, brilliant, and illuminating as his extraordinarily successful biography of cancer. Weaving science, social history, and personal narrative to tell us the story of one of the most important conceptual breakthroughs of modern times, Mukherjee animates the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

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.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

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.

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.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

Explore the world through its most unlikely creatures: Cryptozoology, the study of hidden, monstrous, and legendary animals, is truly the art of discovering the unknown. Richard Freeman, Zoological Director of Centre for Fortean Zoology, has explored the corners of the five continents on the search for creatures that many people believe are non-existent. In this book, he shares the exciting stories of his investigations of the Yeti, Mongolian Deathworm, Loch Ness Monster, Orang-Pendak, Ninki-Naka, and more.

Penguin presents the audiobook edition of Blueprint, written and read by Robert Plomin. The blueprint for our individuality lies in the 1 percent of DNA that differs between people. Our intellectual capacity, our introversion or extraversion, our vulnerability to mental illness, even whether we are a morning person - all of these aspects of our personality are profoundly shaped by our inherited DNA differences.

The Origin of Humankind is Richard Leakey's personal view of the development of Homo sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: Once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes.

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.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

Leading archaeogeneticist Johannes Krause and journalist Thomas Trappe investigate what DNA can tell us about how we got where we are and what our future might be. They show how the first humans were defeated again and again and suffered fatal setbacks, and how Homo sapiens succeeded in conquering continents, overcoming natural borders, and bringing other species under its control. But the genetic blueprint that enabled us to get to the place where we are today had one flaw: it didn't factor in planetary boundaries.

Cooperation is the means by which life arose in the first place. It’s how we progressed through scale and complexity, from free-floating strands of genetic material, to nation states. But given what we know about the mechanisms of evolution, cooperation is also something of a puzzle. How does cooperation begin, when on a Darwinian level, all that the genes in your body care about is being passed on to the next generation? A biologist by training, Raihani looks at where and how collaborative behavior emerges throughout the animal kingdom, and what problems it solves.

When his missionary brother renounced faith in favor of atheism, Perry Marshall was plunged into crisis and doubt. He decided: “I”m going to let science make this decision for me.” He asked: “Is the hand at the end of my arm purposeful? Or is it purposeless?” He leapt into the void of evolution and the origin of life. He could not have begun to anticipate what he was about to discover. Living things were far more sophisticated than textbooks were saying.
