This is not a learned behavior, psychologist Michael Tomasello argues. Through observations of young children in experiments he himself has designed, Tomasello shows that children are naturally--and uniquely--cooperative. Put through similar experiments, for example, apes demonstrate the ability to work together and share, but choose not to. As children grow, their almost reflexive desire to help--without expectation of reward--becomes shaped by culture. They become more aware of being a member of a group. Groups convey mutual expectations, and thus may either encourage or discourage altruism and collaboration. Either way, cooperation emerges as a distinctly human combination of innate and learned behavior. In Why We Cooperate, Tomasello's studies of young children and great apes help identify the underlying psychological processes that very likely supported humans' earliest forms of complex collaboration and, ultimately, our unique forms of cultural organization, from the evolution of tolerance and trust to the creation of such group-level structures as cultural norms and institutions. Scholars Carol Dweck, Joan Silk, Brian Skyrms, and Elizabeth Spelke respond to Tomasello's findings and explore the implications.

    With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the twenty-first century reader.

    Dennett, whom Chet Raymo of The Boston Globe calls "one of the most provocative thinkers on the planet," focuses his unerringly logical mind on the theory of natural selection, showing how Darwin's great idea transforms and illuminates our traditional view of humanity's place in the universe. Dennett vividly describes the theory itself and then extends Darwin's vision with impeccable arguments to their often surprising conclusions, challenging the views of some of the most famous scientists of our day.

    Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    After the Ice is the story of this momentous period--one in which a seemingly minor alteration in temperature could presage anything from the spread of lush woodland to the coming of apocalyptic floods--and one in which we find the origins of civilization itself.Drawing on the latest research in archaeology, human genetics, and environmental science, After the Ice takes the reader on a sweeping tour of 15,000 years of human history. Steven Mithen brings this world to life through the eyes of an imaginary modern traveler--John Lubbock, namesake of the great Victorian polymath and author of Prehistoric Times. With Lubbock, readers visit and observe communities and landscapes, experiencing prehistoric life--from aboriginal hunting parties in Tasmania, to the corralling of wild sheep in the central Sahara, to the efforts of the Guila Naquitz people in Oaxaca to combat drought with agricultural innovations.Part history, part science, part time travel, After the Ice offers an evocative and uniquely compelling portrayal of diverse cultures, lives, and landscapes that laid the foundations of the modern world.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?

    Through a series of entertaining, bite-sized chapters that combine anthropological insight with cutting-edge science, we gain fresh perspectives into our first hominin ancestors and ways to challenge perceptions about the traditional progression of evolution. With Lee as our guide, we discover that we indeed have always been a species of continuous change.

    This text offers radical but scientifically accurate thinking on the possibility of life on other planets.

    Now, with an astonishing new discovery, everything we thought we knew about primate origins could change. Lying inside a high-security vault, deep within the heart of one of the world's leading natural history museums, is the scientific find of a lifetime - a perfectly fossilized early primate, older than the previously most famous primate fossil, Lucy, by forty-four million years.  A secret until now, the fossil - "Ida" to the researchers who have painstakingly verified her provenance - is the most complete primate fossil ever found. Forty-seven million years old, Ida rewrites what we've assumed about the earliest primate origins. Her completeness is unparalleled - so much of what we understand about evolution comes from partial fossils and even single bones, but Ida's fossilization offers much more than that, from a haunting "skin shadow" to her stomach contents. And, remarkably, knowledge of her discovery and existence almost never saw the light of day. With exclusive access to the first scientists to study her, the award-winning science writer Colin Tudge tells the history of Ida and her place in the world. A magnificent, cutting-edge scientific detective story followed her discovery, and The Link offers a wide-ranging investigation into Ida and our earliest origins. At the same time, it opens a stunningly evocative window into our past and changes what we know about primate evolution and, ultimately, our own.

    This introductory book provides an overview of the key theoretical principles of human sociobiology and evolutionary psychology and shows how they illuminate the ways humans think and behave. The book takes as one of its main premises the idea that we think, feel, and act in ways that once enhanced the reproductive success of our ancestors.The book covers fundamental issues such as the origins and function of sexual reproduction, mating behavior, human mate choice, patterns of violence in families, altruistic behavior, the evolution of brain size and the origins of language, the modular mind, and the relationship between genes and culture. It also examines the larger implications of Darwinism for how we view ourselves as a species and our sense of ourselves as a moral animal. The book includes a valuable historical introduction to evolutionary theories of behavior and concludes with an examination of the social and political ramifications of evolutionary thought. It contains numerous diagrams and illustrations, comprehensive references, summaries, and suggestions for further reading.

    This introductory, one-semester text is designed for non-majors.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    Gee’s grand tour enthusiastically details the narrative underlying life’s erratic and often whimsical exploration of biological form and function.” —Adrian Woolfson, The Washington PostIn the tradition of Richard Dawkins, Bill Bryson, and Simon Winchester—An entertaining and uniquely informed narration of Life's life story.In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor.Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to form membrane-bound bubbles that were mostly-faithful copies of their parents—a foamy lather of soap-bubble cells standing as tiny clenched fists, defiant against the lifeless world. Life on this planet has continued in much the same way for millennia, adapting to literally every conceivable setback that living organisms could encounter and thriving, from these humblest beginnings to the thrilling and unlikely story of ourselves.In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor. Drawing on the very latest scientific understanding and writing in a clear, accessible style, he tells an enlightening tale of survival and persistence that illuminates the delicate balance within which life has always existed.
