| recent adaptations in humans answer key: Understanding Climate's Influence on Human Evolution National Research Council, Division on Earth and Life Studies, Board on Earth Sciences and Resources, Committee on the Earth System Context for Hominin Evolution, 2010-04-17 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. |

| recent adaptations in humans answer key: What Does it Mean to be Human? Richard Potts, Christopher Sloan, 2010 This generously illustrated book tells the story of the human family, showing how our species' physical traits and behaviors evolved over millions of years as our ancestors adapted to dramatic environmental changes. In What Does It Means to Be Human? Rick Potts, director of the Smithsonian's Human Origins Program, and Chris Sloan, National Geographic's paleoanthropolgy expert, delve into our distant past to explain when, why, and how we acquired the unique biological and cultural qualities that govern our most fundamental connections and interactions with other people and with the natural world. Drawing on the latest research, they conclude that we are the last survivors of a once-diverse family tree, and that our evolution was shaped by one of the most unstable eras in Earth's environmental history. The book presents a wealth of attractive new material especially developed for the Hall's displays, from life-like reconstructions of our ancestors sculpted by the acclaimed John Gurche to photographs from National Geographic and Smithsonian archives, along with informative graphics and illustrations. In coordination with the exhibit opening, the PBS program NOVA will present a related three-part television series, and the museum will launch a website expected to draw 40 million visitors. |

| recent adaptations in humans answer key: Human Dimension and Interior Space Julius Panero, Martin Zelnik, 2014-01-21 The study of human body measurements on a comparative basis is known as anthropometrics. Its applicability to the design process is seen in the physical fit, or interface, between the human body and the various components of interior space. Human Dimension and Interior Space is the first major anthropometrically based reference book of design standards for use by all those involved with the physical planning and detailing of interiors, including interior designers, architects, furniture designers, builders, industrial designers, and students of design. The use of anthropometric data, although no substitute for good design or sound professional judgment should be viewed as one of the many tools required in the design process. This comprehensive overview of anthropometrics consists of three parts. The first part deals with the theory and application of anthropometrics and includes a special section dealing with physically disabled and elderly people. It provides the designer with the fundamentals of anthropometrics and a basic understanding of how interior design standards are established. The second part contains easy-to-read, illustrated anthropometric tables, which provide the most current data available on human body size, organized by age and percentile groupings. Also included is data relative to the range of joint motion and body sizes of children. The third part contains hundreds of dimensioned drawings, illustrating in plan and section the proper anthropometrically based relationship between user and space. The types of spaces range from residential and commercial to recreational and institutional, and all dimensions include metric conversions. In the Epilogue, the authors challenge the interior design profession, the building industry, and the furniture manufacturer to seriously explore the problem of adjustability in design. They expose the fallacy of designing to accommodate the so-called average man, who, in fact, does not exist. Using government data, including studies prepared by Dr. Howard Stoudt, Dr. Albert Damon, and Dr. Ross McFarland, formerly of the Harvard School of Public Health, and Jean Roberts of the U.S. Public Health Service, Panero and Zelnik have devised a system of interior design reference standards, easily understood through a series of charts and situation drawings. With Human Dimension and Interior Space, these standards are now accessible to all designers of interior environments. |
| recent adaptations in humans answer key: The Story of the Human Body Daniel Lieberman, 2014-07-01 A landmark book of popular science that gives us a lucid and engaging account of how the human body evolved over millions of years—with charts and line drawings throughout. “Fascinating.... A readable introduction to the whole field and great on the making of our physicality.”—Nature In this book, Daniel E. Lieberman illuminates the major transformations that contributed to key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering; and how cultural changes like the Agricultural and Industrial Revolutions have impacted us physically. He shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning a paradox: greater longevity but increased chronic disease. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes even compel us to create a more salubrious environment and pursue better lifestyles. |

| recent adaptations in humans answer key: Adaptation and Natural Selection George Christopher Williams, 2018-10-30 Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate. |
| recent adaptations in humans answer key: Global Environmental Change National Research Council, Division of Behavioral and Social Sciences and Education, Board on Environmental Change and Society, Committee on the Human Dimensions of Global Change, 1991-02-01 Global environmental change often seems to be the most carefully examined issue of our time. Yet understanding the human sideâ€human causes of and responses to environmental changeâ€has not yet received sustained attention. Global Environmental Change offers a strategy for combining the efforts of natural and social scientists to better understand how our actions influence global change and how global change influences us. The volume is accessible to the nonscientist and provides a wide range of examples and case studies. It explores how the attitudes and actions of individuals, governments, and organizations intertwine to leave their mark on the health of the planet. The book focuses on establishing a framework for this new field of study, identifying problems that must be overcome if we are to deepen our understanding of the human dimensions of global change, presenting conclusions and recommendations. |
| recent adaptations in humans answer key: Review of the Draft Fourth National Climate Assessment National Academies of Sciences, Engineering, and Medicine, Division of Behavioral and Social Sciences and Education, Division on Earth and Life Studies, Board on Environmental Change and Society, Board on Atmospheric Sciences and Climate, Committee to Review the Draft Fourth National Climate Assessment, 2018-06-18 Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders. |
| recent adaptations in humans answer key: How Evolution Shapes Our Lives Jonathan B. Losos, Richard Lenski, 2016 It is easy to think of evolution as something that happened long ago, or that occurs only in nature, or that is so slow that its ongoing impact is virtually nonexistent when viewed from the perspective of a single human lifetime. But we now know that when natural selection is strong, evolutionary change can be very rapid. In this book, some of the world's leading scientists explore the implications of this reality for human life and society. With some twenty-five essays, this volume provides authoritative yet accessible explorations of why understanding evolution is crucial to human life--from dealing with climate change and ensuring our food supply, health, and economic survival to developing a richer and more accurate comprehension of society, culture, and even what it means to be human itself. Combining new essays with ones revised and updated from the acclaimed Princeton Guide to Evolution, this collection addresses the role of evolution in aging, cognition, cooperation, religion, the media, engineering, computer science, and many other areas. The result is a compelling and important book about how evolution matters to humans today. The contributors include Francisco J. Ayala, Dieter Ebert, Elizabeth Hannon, Richard E. Lenski, Tim Lewens, Jonathan B. Losos, Jacob A. Moorad, Mark Pagel, Robert T. Pennock, Daniel E. L. Promislow, Robert C. Richardson, Alan R. Templeton, and Carl Zimmer.-- |

| recent adaptations in humans answer key: First Steps Jeremy DeSilva, 2021-04-06 A Science News Best Science Book of the Year: “A brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution.” —Agustín Fuentes, PhD, author of The Creative Spark: How Imagination Made Humans Exceptional Winner of the W.W. Howells Book Prize from the American Anthropological Association Blending history, science, and culture, this highly engaging evolutionary story explores how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, this book shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities to our thirst for exploration and our use of language—and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Includes photographs “A book that strides confidently across this complex terrain, laying out what we know about how walking works, who started doing it, and when.” —The New York Times Book Review “DeSilva makes a solid scientific case with an expert history of human and ape evolution.” —Kirkus Reviews “A brisk jaunt through the history of bipedalism . . . will leave readers both informed and uplifted.” —Publishers Weekly “Breezy popular science at its best.” —Science News |
| recent adaptations in humans answer key: The Descent of Man, and Selection in Relation to Sex Charles Darwin, 2008-09-02 In the current resurgence of interest in the biological basis of animal behavior and social organization, the ideas and questions pursued by Charles Darwin remain fresh and insightful. This is especially true of The Descent of Man and Selection in Relation to Sex, Darwin's second most important work. This edition is a facsimile reprint of the first printing of the first edition (1871), not previously available in paperback. The work is divided into two parts. Part One marshals behavioral and morphological evidence to argue that humans evolved from other animals. Darwin shoes that human mental and emotional capacities, far from making human beings unique, are evidence of an animal origin and evolutionary development. Part Two is an extended discussion of the differences between the sexes of many species and how they arose as a result of selection. Here Darwin lays the foundation for much contemporary research by arguing that many characteristics of animals have evolved not in response to the selective pressures exerted by their physical and biological environment, but rather to confer an advantage in sexual competition. These two themes are drawn together in two final chapters on the role of sexual selection in humans. In their Introduction, Professors Bonner and May discuss the place of The Descent in its own time and relation to current work in biology and other disciplines. |
| recent adaptations in humans answer key: Climate Change and Indigenous Peoples in the United States Julie Koppel Maldonado, Benedict Colombi, Rajul Pandya, 2014-04-05 With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013. |
| recent adaptations in humans answer key: Catching Fire Richard Wrangham, 2010-08-06 In this stunningly original book, Richard Wrangham argues that it was cooking that caused the extraordinary transformation of our ancestors from apelike beings to Homo erectus. At the heart of Catching Fire lies an explosive new idea: the habit of eating cooked rather than raw food permitted the digestive tract to shrink and the human brain to grow, helped structure human society, and created the male-female division of labour. As our ancestors adapted to using fire, humans emerged as the cooking apes. Covering everything from food-labelling and overweight pets to raw-food faddists, Catching Fire offers a startlingly original argument about how we came to be the social, intelligent, and sexual species we are today. This notion is surprising, fresh and, in the hands of Richard Wrangham, utterly persuasive ... Big, new ideas do not come along often in evolution these days, but this is one. -Matt Ridley, author of Genome |

| recent adaptations in humans answer key: A Troublesome Inheritance Nicholas Wade, 2014-05-06 Drawing on startling new evidence from the mapping of the genome, an explosive new account of the genetic basis of race and its role in the human story Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory. Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years—to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well. Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits—thrift, docility, nonviolence—have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These “values” obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews. Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation. |
| recent adaptations in humans answer key: The Secret of Our Success Joseph Henrich, 2017-10-17 How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness. |
| recent adaptations in humans answer key: Aerospace Health and Safety: Today and the Future Irina Mordukhovich, Mardi A. Crane-Godreau, Eileen Mcneely, Christopher Scheibler, 2023-11-20 Aviation plays vital roles in commerce, defense, science and leisure travel. Irrespective of the purpose of flight, crew and passengers are challenged by exposure to a variety of environmental conditions that can differ widely from work and travel environments on the surface of the Earth. With anticipated changes in aviation and space technology, new challenges to health and safety of crew and passengers can be expected. In this Research Topic, we welcome contributions from those whose work and interests are relevant to the health and safety of crew and passengers. This includes, but is not limited to, health and safety professionals, FAA examiners, corporate medical officers, aerospace and occupational physicians, physiologists, military and scientific team members, public health professionals, as well as engineers who are tasked with crew and passenger health and safety design projects. While 4.1 billion passengers fly on commercial airlines annually (and this figure is even higher when taking into account privately owned aircraft and military flight), for the most part aviation is safe. Passengers do arrive at their destinations with little concern to their own well-being and flight is generally well tolerated. However, older flyers, people with (diagnosed or undiagnosed) preexisting disease, and other vulnerable passengers (such as young children and pregnant women) may be at risk of complications and crew may be at special risk due to the frequency and duration of their many flight-related exposures. Health and safety issues for crew and passengers include but are not limited to: potentially severe circadian rhythm disruption, potential health effects of low-level cosmic ionizing radiation exposure at altitude, reduced oxygen delivery and tissue hypoxia at cabin pressurization, cabin air contamination by engine gases, toxic materials used in uniforms and some cabin seat materials, occupational noise, pesticides used for cabin disinsection, lack of adequate crew rest on layovers or between flights, cardiovascular demands of flight and effects of flight-related dehydration, the current absence of screening protocols especially in the context of a rising number of elderly and vulnerable flyers, lack of healthy nutrition at airports and in flight, availability of food and hydration as well as adequate cabin temperature under delay conditions, effects of alcohol use on flight-related physiological and behavioral health risks, anxiety and psychological distress associated with air travel, the effects of long-haul or ultra-long-haul flights on thromboembolic events as well as smoking cessation efforts and related psychological outcomes, job-related stress and harassment among crew. Cosmic ionizing and non-ionizing radiation exposure have drawn attention as have historic exposures of crew and passengers to second-hand cigarette smoke. The threat of political and interpersonal violence and altercations involving aviation cannot be overlooked. On-board medical emergencies run a wide gamut and the capacity to respond becomes more problematic as the duration of flights becomes longer or in the case of flight over oceans and the poles. In addition, in-flight and post flight embolisms and myocardial infarctions are more prevalent than might be expected. We hence encourage manuscripts that address in-flight medical response, including the capabilities on different types of aircraft on potential interventions by crew and medical volunteers. In addition, aviation as a vector for the carriage of disease is a significant concern to public health and security of populations world-wide, and we welcome submissions regarding infectious disease epidemiology and medicine as it relates to air travel. Insects and occasional unplanned travel by birds and rodents can present additional public health concerns. We are approaching an era where space travel may soon be increasingly common. Future flights for near-Earth orbit by leisure travelers and as well as travel to the moon and Mars raise a host of new questions with health and safety implications. What are the proposed health and safety accommodations going to be? Who will be allowed to travel? Perhaps the most interesting question is - who will make the rules? |
| recent adaptations in humans answer key: Childhood's End Arthur C. Clarke, 2012-11-30 In the Retro Hugo Award–nominated novel that inspired the Syfy miniseries, alien invaders bring peace to Earth—at a grave price: “A first-rate tour de force” (The New York Times). In the near future, enormous silver spaceships appear without warning over mankind’s largest cities. They belong to the Overlords, an alien race far superior to humanity in technological development. Their purpose is to dominate Earth. Their demands, however, are surprisingly benevolent: end war, poverty, and cruelty. Their presence, rather than signaling the end of humanity, ushers in a golden age . . . or so it seems. Without conflict, human culture and progress stagnate. As the years pass, it becomes clear that the Overlords have a hidden agenda for the evolution of the human race that may not be as benevolent as it seems. “Frighteningly logical, believable, and grimly prophetic . . .

| recent adaptations in humans answer key: A Framework for K-12 Science Education National Research Council, Division of Behavioral and Social Sciences and Education, Board on Science Education, Committee on a Conceptual Framework for New K-12 Science Education Standards, 2012-02-28 Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments. |

| recent adaptations in humans answer key: The Art of Being Human Michael Wesch, 2018-08-07 Anthropology is the study of all humans in all times in all places. But it is so much more than that. Anthropology requires strength, valor, and courage, Nancy Scheper-Hughes noted. Pierre Bourdieu called anthropology a combat sport, an extreme sport as well as a tough and rigorous discipline. ... It teaches students not to be afraid of getting one's hands dirty, to get down in the dirt, and to commit yourself, body and mind. Susan Sontag called anthropology a heroic profession. What is the payoff for this heroic journey? You will find ideas that can carry you across rivers of doubt and over mountains of fear to find the the light and life of places forgotten. Real anthropology cannot be contained in a book. You have to go out and feel the world's jagged edges, wipe its dust from your brow, and at times, leave your blood in its soil. In this unique book, Dr. Michael Wesch shares many of his own adventures of being an anthropologist and what the science of human beings can tell us about the art of being human. This special first draft edition is a loose framework for more and more complete future chapters and writings. It serves as a companion to anth101.com, a free and open resource for instructors of cultural anthropology. This 2018 text is a revision of the first draft edition from 2017 and includes 7 new chapters. |

| recent adaptations in humans answer key: The Goodness Paradox Richard Wrangham, 2019-01-29 “A fascinating new analysis of human violence, filled with fresh ideas and gripping evidence from our primate cousins, historical forebears, and contemporary neighbors.” —Steven Pinker, author of The Better Angels of Our Nature We Homo sapiens can be the nicest of species and also the nastiest. What occurred during human evolution to account for this paradox? What are the two kinds of aggression that primates are prone to, and why did each evolve separately? How does the intensity of violence among humans compare with the aggressive behavior of other primates? How did humans domesticate themselves? And how were the acquisition of language and the practice of capital punishment determining factors in the rise of culture and civilization? Authoritative, provocative, and engaging, The Goodness Paradox offers a startlingly original theory of how, in the last 250 million years, humankind became an increasingly peaceful species in daily interactions even as its capacity for coolly planned and devastating violence remains undiminished. In tracing the evolutionary histories of reactive and proactive aggression, biological anthropologist Richard Wrangham forcefully and persuasively argues for the necessity of social tolerance and the control of savage divisiveness still haunting us today. |

| recent adaptations in humans answer key: Who We Are and How We Got Here David Reich, 2018-03-29 The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next? |
| recent adaptations in humans answer key: A Different Kind of Animal Robert Boyd, 2019-11-19 Human beings are a very different kind of animal. We have evolved to become the most dominant species on Earth. We have a larger geographical range and process more energy than any other creature alive. This astonishing transformation is usually explained in terms of cognitive ability--people are just smarter than all the rest. But in this compelling book, Robert Boyd argues that culture--our ability to learn from each other--has been the essential ingredient of our remarkable success. A Different Kind of Animal demonstrates that while people are smart, we are not nearly smart enough to have solved the vast array of problems that confronted our species as it spread across the globe. Over the past two million years, culture has evolved to enable human populations to accumulate superb local adaptations that no individual could ever have invented on their own. It has also made possible the evolution of social norms that allow humans to make common cause with large groups of unrelated individuals, a kind of society not seen anywhere else in nature. This unique combination of cultural adaptation and large-scale cooperation has transformed our species and assured our survival--making us the different kind of animal we are today. Based on the Tanner Lectures delivered at Princeton University, A Different Kind of Animal features challenging responses by biologist H. Allen Orr, philosopher Kim Sterelny, economist Paul Seabright, and evolutionary anthropologist Ruth Mace, as well as an introduction by Stephen Macedo.-- |

| recent adaptations in humans answer key: The Causes of Molecular Evolution John H. Gillespie, 1994-05-26 This work provides a unified theory that addresses the important problem of the origin and maintenance of genetic variation in natural populations. With modern molecular techniques, variation is found in all species, sometimes at astonishingly high levels. Yet, despite these observations, the forces that maintain variation within and between species have been difficult subjects of study. Because they act very weakly and operate over vast time scales, scientists must rely on indirect inferences and speculative mathematical models. However, despite these obstacles, many advances have been made. The author's research in molecular genetics, evolution, and bio-mathematics has enabled him to draw on this work, and present a coherent and valuable view of the field. The book is divided into three parts. The first consists of three chapters on protein evolution, DNA evolution, and molecular mechanisms. This section reviews the experimental observations on genetic variation. The second part gives a unified treatment of the mathematical theory of selection in a fluctuating environment. The final two chapters combine the earlier assessments in a treatment of the scientific status of two competing theories for the maintenance of genetic variation. Steeped in the enormous advances population genetics has made over the past 25 years, this book has proven highly popular among human geneticists, biologists, evolutionary theorists, and bio-mathematicians. |
