In this masterwork, Russell H. Tuttle synthesizes a vast research literature in primate evolution and behavior to explain how apes and humans evolved in relation to one another, and why humans became a bipedal, tool-making, culture-inventing species distinct from other hominoids. Along the way, he refutes the influential theory that men are essentially killer apes—sophisticated but instinctively aggressive and destructive beings. Situating humans in a broad context, Tuttle musters convincing evidence from morphology and recent fossil discoveries to reveal what early primates ate, where they slept, how they learned to walk upright, how brain and hand anatomy evolved simultaneously, and what else happened evolutionarily to cause humans to diverge from their closest relatives. Despite our genomic similarities with bonobos, chimpanzees, and gorillas, humans are unique among primates in occupying a symbolic niche of values and beliefs based on symbolically mediated cognitive processes. Although apes exhibit behaviors that strongly suggest they can think, salient elements of human culture—speech, mating proscriptions, kinship structures, and moral codes—are symbolic systems that are not manifest in ape niches. This encyclopedic volume is both a milestone in primatological research and a critique of what is known and yet to be discovered about human and ape potential.

The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

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.

The astonishing new story of human origins Was Darwin wrong when he traced our origins to Africa? The Real Planet of the Apes makes the explosive claim that it was in Europe, not Africa, where apes evolved the most important hallmarks of our human lineage. In this compelling and accessible book, David Begun, one of the world’s leading paleoanthropologists, transports readers to an epoch in the remote past when the Earth was home to many migratory populations of ape species. Begun draws on the latest astonishing discoveries in the fossil record, as well as his own experiences conducting field expeditions, to offer a sweeping evolutionary history of great apes and humans. He tells the story of how one of the earliest members of our evolutionary group evolved from lemur-like monkeys in the primeval forests of Africa. Begun then vividly describes how, over the next ten million years, these hominoids expanded into Europe and Asia and evolved climbing and hanging adaptations, longer maturation times, and larger brains. As the climate deteriorated in Europe, these apes either died out or migrated south, reinvading the African continent and giving rise to the lineages of African great apes, and, ultimately, humans. Presenting startling new insights, The Real Planet of the Apes fundamentally alters our understanding of human origins.

In this New York Times bestseller and longlist nominee for the National Book Award, “our greatest living chronicler of the natural world” (The New York Times), David Quammen explains how recent discoveries in molecular biology affect our understanding of evolution and life’s history. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important; we now know that roughly eight percent of the human genome arrived sideways by viral infection—a type of HGT. In The Tangled Tree, “the grandest tale in biology….David Quammen presents the science—and the scientists involved—with patience, candor, and flair” (Nature). We learn about the major players, such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. “David Quammen proves to be an immensely well-informed guide to a complex story” (The Wall Street Journal). In The Tangled Tree, he explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. “The Tangled Tree is a source of wonder….Quammen has written a deep and daring intellectual adventure” (The Boston Globe).

Detailing the unfolding discovery of a crucial link in our evolution, this book is written in the voice of Walker, whose involvement with Proconsul began when his graduate supervisor analyzed the tree-climbing adaptations in the arm and hand of this extinct creature. Today, Proconsul is the best-known fossil ape in the world.
