In this dynamic account, award-winning science writer Ann Gibbons chronicles an extraordinary quest to answer the most primal of questions: When and where was the dawn of humankind?Following four intensely competitive international teams of scientists in a heated race to find the “missing link”–the fossil of the earliest human ancestor–Gibbons ventures to Africa, where she encounters a fascinating array of fossil hunters: Tim White, the irreverent Californian who discovered the partial skeleton of a primate that lived 4.4 million years ago in Ethiopia; French paleontologist Michel Brunet, who uncovers a skull in Chad that could date the beginnings of humankind to seven million years ago; and two other groups–one led by zoologist Meave Leakey, the other by British geologist Martin Pickford and his French paleontologist partner, Brigitte Senut–who enter the race with landmark discoveries of their own. Through scrupulous research and vivid first-person reporting, The First Human reveals the perils and the promises of fossil hunting on a grand competitive scale.
In 2001, scientists were finally able to determine the full human genome sequence, and with the discovery began a genomic voyage back in time. Since then, we have sequenced the full genomes of a number of mankind's primate relatives at a remarkable rate. The genomes of the common chimpanzee (2005) and bonobo (2012), orangutan (2011), gorilla (2012), and macaque monkey (2007) have already been identified, and the determination of other primate genomes is well underway. Researchers are beginning to unravel our full genomic history, comparing it with closely related species to answer age-old questions about how and when we evolved. For the first time, we are finding our own ancestors in our genome and are thereby gleaning new information about our evolutionary past. In Ancestors in Our Genome, molecular anthropologist Eugene E. Harris presents us with a complete and up-to-date account of the evolution of the human genome and our species. Written from the perspective of population genetics, and in simple terms, the book traces human origins back to their source among our earliest human ancestors, and explains many of the most intriguing questions that genome scientists are currently working to answer. For example, what does the high level of discordance among the gene trees of humans and the African great apes tell us about our respective separations from our common ancestor? Was our separation from the apes fast or slow, and when and why did it occur? Where, when, and how did our modern species evolve? How do we search across genomes to find the genomic underpinnings of our large and complex brains and language abilities? How can we find the genomic bases for life at high altitudes, for lactose tolerance, resistance to disease, and for our different skin pigmentations? How and when did we interbreed with Neandertals and the recently discovered ancient Denisovans of Asia? Harris draws upon extensive experience researching primate evolution in order to deliver a lively and thorough history of human evolution. Ancestors in Our Genome is the most complete discussion of our current understanding of the human genome available.
This breakthrough book brings science into history to offer a dazzling new vision of humanity across time. Team-written by leading experts in a variety of fields, it maps events, cultures, and eras across millions of years to present a new scale for understanding the human body, energy and ecosystems, language, food, kinship, migration, and more.
The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture. The Earth's geological record suggests that some evolutionary events were coincident with substantial changes in African and Eurasian climate, raising the possibility that critical junctures in human evolution and behavioral development may have been affected by the environmental characteristics of the areas where hominins evolved. Understanding Climate's Change on Human Evolution explores the opportunities of using scientific research to improve our understanding of how climate may have helped shape our species. Improved climate records for specific regions will be required before it is possible to evaluate how critical resources for hominins, especially water and vegetation, would have been distributed on the landscape during key intervals of hominin history. Existing records contain substantial temporal gaps. The book's initiatives are presented in two major research themes: first, determining the impacts of climate change and climate variability on human evolution and dispersal; and second, integrating climate modeling, environmental records, and biotic responses. Understanding Climate's Change on Human Evolution suggests a new scientific program for international climate and human evolution studies that involve an exploration initiative to locate new fossil sites and to broaden the geographic and temporal sampling of the fossil and archeological record; a comprehensive and integrative scientific drilling program in lakes, lake bed outcrops, and ocean basins surrounding the regions where hominins evolved and a major investment in climate modeling experiments for key time intervals and regions that are critical to understanding human evolution.
The discoveries of the last decade have brought about a completely revised understanding of human evolution due to the recent advances in genetics, palaeontology, ecology, archaeology, geography, and climate science. Written by two leading authorities in the fields of physical anthropology and molecular evolution, Processes in Human Evolution presents a reconsidered overview of hominid evolution, synthesising data and approaches from a range of inter-disciplinary fields. The authors pay particular attention to population migrations - since these are crucial in understanding the origin and dispersion of the different genera and species in each continent - and to the emergence of the lithic cultures and their impact on the evolution of cognitive capacities. Processes in Human Evolution is intended as a primary textbook for university courses on human evolution, and may also be used as supplementary reading in advanced undergraduate and graduate courses. It is also suitable for a more general audience seeking a readable but up-to-date and inclusive treatment of human origins and evolution.
"Splendid and important... Scientifically rigorous and written with a clarity and candor that create a gripping tale... [Böhme's] account of the history of Europe's lost apes is imbued with the sweat, grime, and triumph that is the lot of the fieldworker, and carries great authority." —Tim Flannery, The New York Review of Books In this "fascinating forensic inquiry into human origins" (Kirkus STARRED Review), a renowned paleontologist takes readers behind-the-scenes of one of the most groundbreaking archaeological digs in recent history. Somewhere west of Munich, paleontologist Madelaine Böhme and her colleagues dig for clues to the origins of humankind. What they discover is beyond anything they ever imagined: the twelve-million-year-old bones of Danuvius guggenmosi make headlines around the world. This ancient ape defies prevailing theories of human history—his skeletal adaptations suggest a new common ancestor between apes and humans, one that dwelled in Europe, not Africa. Might the great apes that traveled from Africa to Europe before Danuvius's time be the key to understanding our own origins? All this and more is explored in Ancient Bones. Using her expertise as a paleoclimatologist and paleontologist, Böhme pieces together an awe-inspiring picture of great apes that crossed land bridges from Africa to Europe millions of years ago, evolving in response to the challenging conditions they found. She also takes us behind the scenes of her research, introducing us to former theories of human evolution (complete with helpful maps and diagrams), and walks us through musty museum overflow storage where she finds forgotten fossils with yellowed labels, before taking us along to the momentous dig where she and the team unearthed Danuvius guggenmosi himself—and the incredible reverberations his discovery caused around the world. Praise for Ancient Bones: "Readable and thought-provoking. Madelaine Böhme is an iconoclast whose fossil discoveries have challenged long-standing ideas on the origins of the ancestors of apes and humans." —Steve Brusatte, New York Times-bestselling author of The Rise and Fall of the Dinosaurs "An inherently fascinating, impressively informative, and exceptionally thought-provoking read." —Midwest Book Review "An impressive introduction to the burgeoning recalibration of paleoanthropology." —Kirkus Reviews (starred review)
The epic story of our evolution in seven big steps! How did we become who we are? With trademark wit, acclaimed science writer Pamela S. Turner breaks down human evolution into the seven most important steps leading to Homo sapiens. How, when, and why did we: 1.stand up, 2.smash rocks, 3.get swelled heads, 4.take a hike, 5.invent barbecue, 6.start talking (and never shut up), and 7.become storytellers? This fascinating, wickedly funny account of our evolutionary journey turns science into an irresistible story. Vetted by experts at the Smithsonian's Human Origins Program, the book also features incredibly detailed portraits by celebrated paleo-artist John Gurche that bring our early ancestors to life.
A renowned biologist provides a sweeping chronicle of more than four billion years of life on Earth, shedding new light on evolutionary theory and history, sexual selection, speciation, extinction, and genetics.
The evolution of bipedalism - the story of why our ancestors stood up - is examined in this text, which presents an entirely new account of how four legged apes became two legged hominids. Kingdon also addresses the problems caused by the proliferation of hominid fossil species, of which up to 20 have been listed.
