This compelling book introduces a bold new theory on this unsolved mystery. Author Richard Klein reexamines the archaeological evidence and brings in new discoveries in the study of the human brain. These studies detail the changes that enabled humans to think and behave in far more sophisticated ways than before, resulting in the incredibly rapid evolution of new skills. Richard Klein has been described as "the premier anthropologist in the country today" by Evolutionary Anthropology. Here, he and coauthor Blake Edgar shed new light on the full story of a truly fascinating period of evolution.Richard G. Klein, PhD (Palo Alto, CA), is a Professor of Anthropology at Stanford University. He is the author of the definitive academic book on the subject of the origins of human culture, The Human Career. Blake Edgar (San Francisco, CA) is the coauthor of the very successful From Lucy to Language, with Dr. Donald Johanson. He has written extensively for Discover, GEO, and numerous other magazines.

    Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personalaspects of being human.Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorterlifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns--the blank spots on the human evolutionarymap, the terra incognita of our own species--and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science atits cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations.Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the not-yet-known for those interested in stretching their scientific imaginations.

    But in Catching Fire, renowned primatologist Richard Wrangham presents a startling alternative: our evolutionary success is the result of cooking. In a groundbreaking theory of our origins, Wrangham shows that the shift from raw to cooked foods was the key factor in human evolution. when our ancestors adapted to using fire, humanity began.Once our hominid ancestors began cooking their food, the human digestive tract shrank and the brain grew. Time once spent chewing tough raw food could be used instead to hunt and to tend camp. Cooking became the basis for pair bonding and marriage, created the household, and even led to a sexual division of labor.Tracing the contemporary implications of our ancestors' diets, Catching Fire sheds new light on how we came to be the social, intelligent, and sexual species we are today. A pathbreaking new theory of human evolution, Catching Fire will provoke controversy and fascinate anyone interested in our ancient origins--or in our modern eating habits.--from the dustjacket

    She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of “reviving” extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia’s Pleistocene Park—a daring attempt to rebuild the mammoth’s ancient ecosystem in order to save earth from climate apocalypse. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field.But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and extinction philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an “unextinct” creature back into the wild? How can we care for these strange animals and ensure their comfort and safety—not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate?By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science.

    But countless questions remain about our great journey from the birthplace of Homo sapiens to the ends of the Earth. How did we end up where we are? When did we get there? Why do we display such a wide range of colors and features? The fossil record offers some answers, but exciting new genetic research reveals many more, since our DNA carries a complete chronicle of our species and its migrations. In Deep Ancestry, scientist and explorer Spencer Wells shows how tiny genetic changes add up over time into a fascinating story. Using scores of real-life examples, helpful analogies, and detailed diagrams and illustrations, he translates complicated concepts into accessible language and explains exactly how each and every individual's DNA contributes another piece to the jigsaw puzzle of human history. The book takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of population genetic DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe. Traveling backward through time from today's scattered billions to the handful of early humans who are ancestors to us all, Deep Ancestry shows how universal our human heritage really is. It combines sophisticated science with our compelling interest in family history and ethnic identity—and transcends humankind's shallow distinctions and superficial differences to touch the depths of our common origins.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    In addition to fieldwork and traditional methods, paleoanthropologists and archaeologists now draw upon genetics and other cutting-edge scientific techniques. In fifty chapters, Prehistoric Investigations tells the story of the many thought-provoking discoveries that have transformed our understanding of the distant past.

    Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring.In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

    Gases and dust particles ejected into the atmosphere changed weather patterns around the world, resulting in the infamous ''year without a summer'' in North America, food riots in Europe, and a widespread cholera epidemic. And the gloomy weather inspired Mary Shelley to write the gothic novel Frankenstein.This book tells the story of nine such epic volcanic events, explaining the related geology for the general reader and exploring the myriad ways in which the earth's volcanism has affected human history. Zeilinga de Boer and Sanders describe in depth how volcanic activity has had long-lasting effects on societies, cultures, and the environment. After introducing the origins and mechanisms of volcanism, the authors draw on ancient as well as modern accounts--from folklore to poetry and from philosophy to literature. Beginning with the Bronze Age eruption that caused the demise of Minoan Crete, the book tells the human and geological stories of eruptions of such volcanoes as Vesuvius, Krakatau, Mount Pel�e, and Tristan da Cunha. Along the way, it shows how volcanism shaped religion in Hawaii, permeated Icelandic mythology and literature, caused widespread population migrations, and spurred scientific discovery.From the prodigious eruption of Thera more than 3,600 years ago to the relative burp of Mount St. Helens in 1980, the results of volcanism attest to the enduring connections between geology and human destiny.

    "Reading The Neanderthal Enigma is like sitting down with a wonderful storyteller in the cave where stories began." -- Jonathan Weiner, author of The Beak of the Finch..

    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    It is based on the assumption that the human mind must have evolved; that self-consciousness must have a biological basis. It then uses plain language to take the reader through some difficult territory: the origins of language, the evolution of habits of thought, and the "mapping" of the world in the brain which creates awareness. It ends up with the controversial conclusion that the human mind is only a few degrees different from an animal's and that self-consciousness, memory, and higher emotions are all simple language-driven abilities which we pick up as children.

    It reads like a novel, but it is one of the most important scientific works ever published. The community is Gombe, on the shores of Lake Tangganyika, where the principal residents are chimpanzees and one extraordinary woman who is their student, protector, and historian. In her classic In the Shadow of Man, Jane Goodall wrote of her first ten years at Gombe. In Through a Window she brings the story up to the present, painting a much more complete and vivid portrait of our closest relative. We see the community split in two and a brutal war break out. We watch young Figan's relentless rise to power and old Mike's crushing defeat. We learn how one mother rears her children to succeed and another dooms them to failure. We witness horrifying murders, touching moments of affection, joyous births, and wrenching deaths. In short, we see every emotion known to humans stripped to its essence. In the mirror of chimpanzee life, we see ourselves reflected. Perhaps the best book ever written about animal behavior, Through a Window is also essential reading for anyone seeking a better grasp of human behavior.

    Probably most or even all of the above. The story of our home planet and the organisms spread across its surface is far more spectacular than any Hollywood blockbuster, filled with enough plot twists to rival a bestselling thriller. But only recently have we begun to piece together the whole mystery into a coherent narrative. Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing twenty first-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.Features original illustrations depicting Earth history and nearly 50 figures (maps, tables, photographs, graphs).

    In this gripping account, David Quammen takes the reader along on this astonishing quest to learn how, where from, and why these diseases emerge and asks the terrifying question: What might the next big one be?
