Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution.Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents? How have cultural innovations affected the growth and spread of populations? What is the connection between genes and languages? Always provocative and often astonishing, Cavalli-Sforza explains why there is no genetic basis for racial classification.

    New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.

    Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.

    Brian Arthur puts forth the first complete theory of the origins and evolution of technology, in a major work that achieves for the invention of new technologies what Darwin’s theory achieved for the emergence of new species. Brian Arthur is a pioneer of complexity theory and the discoverer of the highly influential "theory of increasing returns," which took Silicon Valley by storm, famously explaining why some high-tech companies achieve breakaway success. Now, in this long-awaited and ground-breaking book, he solves the great outstanding puzzle of technology—where do transformative new technologies come from?—putting forth the first full theory of how new technologies emerge and offering a definitive answer to the mystery of why some cultures—Silicon Valley, Cambridge, England in the 1920s—are so extraordinarily inventive. He has discovered that rather than springing from insight moments of individual genius, new technologies arise in a process akin to evolution. Technology evolves by creating itself out of itself, much as a coral reef builds itself from activities of small organisms. Drawing on a wealth of examples, from the most ancient to cutting-edge inventions of today, Arthur takes readers on a delightful intellectual journey, bringing to life the wonders of this process of technological evolution. The Nature of Technology is the work of one of our greatest thinkers at the top of his game, composing a classic for our times that is sure to generate wide acclaim.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    Created primarily for medical and premedical students, 'Neuroscience' emphasizes the structure of the nervous system, the correlation of structure and function, and the structure/function relationships particularly pertinent to the practice of medicine.

    By examining fossils and DNA, Shubin shows us that our hands actually resemble fish fins, our head is organized like that of a long-extinct jawless fish, and major parts of our genome look and function like those of worms and bacteria.Shubin makes us see ourselves and our world in a completely new light. Your Inner Fish is science writing at its finest-enlightening, accessible, and told with irresistible enthusiasm.

    The Big Questions series is designed to let renowned experts address the 20 most fundamental and frequently asked questions of a major branch of science or philosophy. Each 3,000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, and provides answers based on the latest research. This ambitious project is a unique distillation of humanity's best ideas. In "The Big Questions: Evolution," Francisco Ayala answers the 20 key questions: What is evolution? Was Darwin right? What is natural selection? What is survival of the fittest? Is evolution a random process? What is a species? What are chromosomes, genes and DNA? How do genes build bodies? What is molecular evolution? How did life begin? What is the tree of life? Am I really a monkey? What does the fossil record tell us? What is the missing link? Is intelligence inherited? Will humans continue to evolve? Can I clone myself? Where does morality come from? Is language a uniquely human attribute? Is Creationism true?

    Unlike Origin, this book focuses on human ancestry and offers a concise, nontechnical survey of the state of mid-nineteenth-century knowledge about primate and human paleontology and ethology.Man's Place in Nature concurs with Darwin's assertion of the absence of a physiologic and psychic structural line of demarcation between humans and apes. Huxley ventures further than Darwin, however, by making the first attempt to apply the principles of evolution directly to the human race (an issue that Darwin skirted). Despite Huxley's acknowledgements of the wide gulf represented by the human capacity for rational speech and language, some Victorian readers were scandalized by the application of Darwinian theory to humans and by Huxley's evidence of the fundamental similarities between the human brain and the ape brain.A landmark of scientific progress, this immensely readable book reflects the stylistic gifts that made its author a popular public speaker.

    Each clique of scientists has a part of the story correct, but new evidence shows they are all fundamentally wrong.On the one side, we have academics highlighting the astonishing fossil record of China with multiple sites now producing modern human fossils aged between 80 - 120 thousand years, or older. Several extremely ancient fossil finds in China, including Dali, Maba and Jinniushan, place archaic Homo sapiens in this region up to 260,000 years ago.On the other side, we have scientists pointing to Africa's impressive fossil record with its evidence of potential ancestors going back around 6 million years. The evidence of extreme genetic diversity among Africans and the discovery of 300,000-year-old archaic Homo sapiens fossils in Morocco tends to further support the idea that humans came out from Africa. We can understand why both sides are so sure of their positions, and why the debate continues. While leading academics focussed on their own agendas, they overlooked significant evidence. Between the two poles of Out of Africa and Out of Asia Theory, exists a 'Middle Way'. The Forgotten Exodus: The Into Africa Theory of Human Evolution, reveals that within the known fossil record, the current genetic studies and recent paleoclimate models there is compelling evidence for a superior theory of human origins, representing a paradigm displacement.The Into Africa Theory does not dispute the evidence placing the earliest hominins in Africa.However, it does not agree with the consensus view that Homo sapiens emerged there first and later migrated to Eurasia.The Into Africa Theory recognises the extraordinary evidence for critical stages in our development occurring in East and Southeast Asia. It is abundantly clear that as a new concerted effort to gather and evaluate fossil evidence begins in earnest we see astonishing new discoveries. The Into Africa Theorydisputes the claims of Out of Africa and Out of Asia(or Europe) adherents over the starting point for the migration which populated Eurasia approximately 60,000 years ago and identifies the actual location.Amazing facts that you will encounter:-Homo heidelbergensis was not ancestral to modern humans -Denisovan fossils in Siberia carried DNAfrom Australian Aboriginals-An Indonesian supervolcano brought about the end for multiple hominin species-Climate catastrophe locked humans in Africa from 73,000 to 59,000 years ago-There is no African fossil DNA over 10,000 years in age-While supposedly isolated, Aboriginal Australians interbred with Denisovans 44,000 years agoYou will gain access to a long-forgotten conversation involving the famous evolutionary scientists Allan Wilson and Rebecca Cann, in which they admitted that their data suggested Aboriginal Australians were ancestral to all modern humans.Learn why the appearance of the haplogroups foundational to Eurasians, L3 and CT, had to come from a population incursion rather than an in-situ mutation.Explore the cutting-edge scientific findings of 2016 and 2017 alongside a broad range of anomalies long suppressed or ignored in academic circles.The Forgotten Exodus' author Bruce R. Fenton began his journey towards a new understanding of human origins after an expedition to a mysterious megalithic complex in the Ecuadorian Amazon. The Information Systems professional and lifelong scholar of ancient cultures, found himself tracing the threads of the human story across six continents and through 6,000,000 years of history. You will come away with a unique view of humanity and a sense of excitement for revelations still set to arrive. This book reminds all of us that we have a collective ability to overcome enormous obstacles.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA.We learn that Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species’ interactions. His findings have not only redrawn our family tree, but recast the fundamentals of human history—the biological beginnings of fully modern Homo sapiens, the direct ancestors of all people alive today.A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.

    De Waal reminds readers through his account of the chimps' sexual rivalries and coalitions, and intelligent rather than instinctual actions, that the roots of politics are older than humanity.

    Its authors present a new view of cognition that has important social and ethical implications, for, they assert, the only world we humans can have is the one we create together through the actions of our coexistence. Written for a general audience as well as for students, scholars, and scientists and abundantly illustrated with examples from biology, linguistics, and new social and cultural phenomena, this revised edition includes a new afterword by Dr. Varela, in which he discusses the effect the book has had in the years since its first publication.
