This Penguin Classics edition is edited with an introduction by James Moore and Adrian Desmond.In The Origin of Species, Charles Darwin refused to discuss human evolution, believing the subject too 'surrounded with prejudices'. He had been reworking his notes since the 1830s, but only with trepidation did he finally publish The Descent of Man in 1871. The book notoriously put apes in our family tree and made the races one family, diversified by 'sexual selection' - Darwin's provocative theory that female choice among competing males leads to diverging racial characteristics. Named by Sigmund Freud as 'one of the ten most significant books' ever written, Darwin's Descent of Man continues to shape the way we think about what it is that makes us uniquely human.In their introduction, James Moore and Adrian Desmond, acclaimed biographers of Charles Darwin, call for a radical re-assessment of the book, arguing that its core ideas on race were fired by Darwin's hatred of slavery. The text is the second and definitive edition and this volume also contains suggestions for further reading, a chronology and biographical sketches of prominent individuals mentioned.Charles Darwin (1809-82), a Victorian scientist and naturalist, has become one of the most famous figures of science to date. The advent of On the Origin of Species by Means of Natural Selection in 1859 challenged and contradicted all contemporary biological and religious beliefs.If you enjoyed The Descent of Man, you might like Darwin's On the Origin of Species, also available in Penguin Classics.

    From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

    Elizabeth Blackburn discovered a biological indicator called telomerase, the enzyme that replenishes telomeres, which protect our genetic heritage. Dr. Blackburn and Dr. Elissa Epel's research shows that the length and health of one's telomeres are a biological underpinning of the long-hypothesized mind-body connection. They and other scientists have found that changes we can make to our daily habits can protect our telomeres and increase our health spans (the number of years we remain healthy, active, and disease-free).THE TELOMERE EFFECT reveals how Blackburn and Epel's findings, together with research from colleagues around the world, cumulatively show that sleep quality, exercise, aspects of diet, and even certain chemicals profoundly affect our telomeres, and that chronic stress, negative thoughts, strained relationships, and even the wrong neighborhoods can eat away at them. Drawing from this scientific body of knowledge, they share lists of foods and suggest amounts and types of exercise that are healthy for our telomeres, mind tricks you can use to protect yourself from stress, and information about how to protect your children against developing shorter telomeres, from pregnancy through adolescence. And they describe how we can improve our health spans at the community level, with neighborhoods characterized by trust, green spaces, and safe streets. THE TELOMERE EFFECT will make you reassess how you live your life on a day-to-day basis. It is the first book to explain how we age at a cellular level and how we can make simple changes to keep our chromosomes and cells healthy, allowing us to stay disease-free longer and live more vital and meaningful lives.

    The 10,000 Year Explosion: How Civilization Accelerated Human Evolution

    . . . Anyone with the slightest interest in biology should read this book."--The New York Times Book Review"A marvelous museum of the past four billion years on earth--capacious, jammed with treasures, full of learning and wide-eyed wonder."--The Boston GlobeFrom its origins on the still-forming planet to the recent emergence of Homo sapiens--one of the world's leading paleontologists offers an absorbing account of how and why life on earth developed as it did. Interlacing the tale of his own adventures in the field with vivid descriptions of creatures who emerged and disappeared in the long march of geologic time, Richard Fortey sheds light upon a fascinating array of evolutionary wonders, mysteries, and debates. Brimming with wit, literary style, and the joy of discovery, this is an indispensable book that will delight the general reader and the scientist alike."A drama bolder and more sweeping than Gone with the Wind . . . a pleasure to read."--Science"A beautifully written and structured work . . . packed with lucid expositions of science."--Natural History

    The complex behavior of birds recounted here demonstrates that birds have sophisticated mental abilities previously unrecognized by conventional avian research. Ackerman supports her thesis with descriptions of the behavior of an entertaining variety of birds from across the world. She brings scientific research alive with personal field observations and accounts of her encounters with colorful and fascinating birds. Throughout, Ackerman reminds readers that birds are thinking beings--their brains are wired differently than those of mammals, giving them increased brain power despite their small size. She further makes the case that bird intelligence shows that humankind is not alone in using language and tools or constructing complex structures and manipulating other creatures.

    No one can stop him--but he walks away. A miracle? No...dysentery. Microbes saved the Roman Empire. Nearly a millennium later, the microbes of the Black Death ended the Middle Ages, making possible the Renaissance, western democracy, and the scientific revolution. Soon after, microbes ravaged the Americas, paving the way for their European conquest. Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species. The "good side" of history's worst epidemics The surprising debt we owe to killer diseases Where diseases came from... ...and where they may be going Children of pestilence: disease and civilization From Egypt to Mexico, the Romans to Attila the Hun STDs, sexual behavior, and culture How microbes may shape cultural cycles of puritanism and promiscuity

    The renowned family of paleontologists—Louis Leakey, Mary Leakey, and their son Richard Leakey—has vastly expanded our understanding of human evolution. 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. In fascinating sections on how and why modern humans developed a social organization, culture, and personal behavior, Leakey has much of interest to say about the development of art, language, and human consciousness.

    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 A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off and transformed our understanding of sexual selection, shedding new light on human behavior in the process.Drawing on cutting-edge work in neuroscience and evolutionary biology, as well as his own important studies of the tiny T�ngara frog deep in the jungles of Panama, Ryan explores the key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers to these questions lie in the brain--particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males. This theory of how sexual beauty evolves explains its astonishing diversity and provides new insights about the degree to which our own perception of beauty resembles that of other animals.Vividly written and filled with fascinating stories, A Taste for the Beautiful will change how you think about beauty and attraction.

    They were hunter-gatherers, consummate foraging experts, but taking the world as they found it. Then a revolution occurred – our ancestors’ interaction with other species changed. They began to tame them. The human population boomed; civilization began.In her new book, Tamed, Alice Roberts uncovers the amazing deep history of ten familiar species with incredible wild pasts: dogs, apples and wheat; cattle; potatoes and chickens; rice, maize, and horses – and, finally, humans. Alice Roberts not only reveals how becoming part of our world changed these animals and plants, but shows how they became our allies, essential to the survival and success of our own species – and to our future.Enlightening, wide-ranging and endlessly fascinating, Tamed is an epic story, encompassing hundreds of thousands of years of history and archaeology alongside cutting-edge genetics and anthropology. Yet it is also a deeply personal journey that will change how we see ourselves and the species on which we have left our mark.

    The answers will surprise and delight you as Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human.Temple Grandin meets Stephen Pinker in this engaging and informative look at what goes on inside the minds of dogs—from a cognitive scientist with a background at The New Yorker.With more than 52 million pet dogs in America today, it’s clear we are a nation of unabashed dog-lovers. Yet the relationship between dogs and humans remains a fascinating mystery, as no one really knows what goes on in the canine mind. Now, in Inside of a Dog, Alexandra Horowitz fuses her perspectives as both scientist and dog-owner to deliver a fresh look at the world of dogs—as seen from the animal’s point of view. Inspired by her years of living with her own dog, Pumpernickel, who was a constant source of delight and mystery, Horowitz’s mind became filled with questions and ideas. In crisp, clear prose, she draws on her research in the field of dog cognition to give readers a sense of a dog’s perceptual and cognitive abilities—and paints a picture of what the canine experience is like. Horowitz’s own scientific journey, and the insights she uncovered, allowed her to understand her dog better and appreciate her more.Containing up-to-the minute research and providing many moments of dog-behavior recognition, this lively and absorbing book helps dog owners to see their best friend’s behavior in a different, and revealing light, allowing them to understand their pets and enjoy their company even more.

    Based on her work at the Santa Fe Institute and drawing on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. Richly illustrated, Complexity: A Guided Tour--winner of the 2010 Phi Beta Kappa Book Award in Science--offers a wide-ranging overview of the ideas underlying complex systems science, the current research at the forefront of this field, and the prospects for its contribution to solving some of the most important scientific questions of our time.

    But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human.From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.

    One of the most important achievements of the past millennium, it did for biology what Galileo did for astronomy: made it into a single science rather than a collection of unrelated facts. Important though Origin remains, its examples and intricate Victorian prose are now a century and a half old. They are ripe for renewal and reaffirmation. Writing as "Darwin's ghost," eminent geneticist Steve Jones updates this seminal work—and restates evolution's case for the 21st century.Jones is a writer of engaging wit and dazzling erudition and has been called "the British Carl Sagan." Using modern examples—the AIDS virus, the puzzles of sexual selection, the physiology and psychology of pets, and the unparalleled genetic success of our own species—he shows the power and immediacy of Darwin's great argument and makes us appreciate how it makes life make sense. Eye-opening and entertaining, filled with astonishing facts, amusing anecdotes, and the very latest research, Darwin's Ghost is contemporary science writing at its very best.

    New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.
