In Maneater, Nagami discusses the shocking and amazing cases of bacterial and viral infections she has encountered in her career as an infectious disease specialist. Through personal accounts, she reveals the facts about some of the deadliest diseases: the warning signs, treatments, and most compellingly, what it feels like to make the medical and ethical decisions that can mean the difference between life and death.

    In this highly informative and entertaining book, the founder of the vibrant new field of evolutionary consumption illuminates the relevance of our biological heritage to our daily lives as consumers. While culture is important, the author shows that innate evolutionary forces deeply influence the foods we eat, the gifts we offer, the cosmetics and clothing styles we choose to make ourselves more attractive to potential mates, and even the cultural products that stimulate our imaginations (such as art, music, and religion). This book demonstrates that most acts of consumption can be mapped onto four key Darwinian drives—namely, survival (we prefer foods high in calories); reproduction (we use products as sexual signals); kin selection (we naturally exchange gifts with family members); and reciprocal altruism (we enjoy offering gifts to close friends). The author further highlights the analogous behaviors that exist between human consumers and a wide range of animals.

    The fastest-growing segment of the population, those beyond the age of fifty, are no longer content to simply cope with the losses of age. Mental acuity and vitality are becoming a life-long pursuit. Now, the science of the mind is catching up with the Baby Boom generation. In this landmark book, renowned psychiatrist Gene Cohen challenges the long-held belief that our brain power inevitably declines as we age, and shows that there are actually positive changes taking place in our minds. Based on the latest studies of the brain, as well as moving stories of men and women in the second half of life, The Mature Mind reveals for the first time how we can continue to grow and flourish. Cohen's groundbreaking theory-the first to elaborate on the psychology of later life-describes how the mind gives us "inner pushes" and creates new opportunities for positive change throughout adult life. He shows how we can jump-start that growth at any age and under any circumstances, fine-tuning as we go, actively building brain reserves and new possibilities. The Mature Mind offers a profoundly different and intriguing look at ourselves, challenging old assumptions, raising bold new questions, and providing exciting answers grounded in science and the realities of everyday life.

    With plenty of engaging material, practice questions, and practical ideas, this updated edition contains everything your students need to succeed in Cambridge IGCSE biology.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    This discovery prompted a complete reevaluation of previous evidence for human origins.In the years since this dramatic discovery Johanson has continued to scour East Africa's Great rift Valley for the earliest evidence of human origins. In 1975 this team unearthed the "First Family", an unparalleled fossil assemblage of 13 individuals dating back to 3.2 million years ago; and in 1986 at the Rift's most famous location, Olduvai Gorge, this same team discovered a 1.8 million-year-old partial adult skeleton that necessitated a reassessment of the earliest members of our own genus Homo.Johanson's fieldwork continues unabated and recently more fossil members of Lucy's family have been found, including the 1992 discovery of the oldest, most complete skull of her species, with future research now planned for 1996 in the virtually unexplored regions of the most northern extension of the Rift Valley in Eritrea.From Lucy to Language is a summing up of this remarkable career and a stunning documentary of human life through time on Earth. It is a combination of the vital experience of field work and the intellectual rigor of primary research. It is the fusion of two great writing talents: Johanson and Blake Edgar, an accomplished science writer, editor of the California Academy of Sciences' Pacific Discovery, and co-author of Johanson's last book, Ancestors.From Lucy to Language is one of the greatest stories ever told, bracketing the timeline between bipedalism and human language. Part I addresses the central issues facing anyone seeking to decipher the mystery of human origins. In this section the authors provide answers to the basics -- "What are our closest living relatives?" -- tackle the controversial -- "What is race?" -- and contemplate the imponderables -- "Why did consciousness evolve?"From Lucy to Language is an encounter with the evidence. Early human fossils are hunted, discovered, identified, excavated, collected, preserved, labeled, cleaned, reconstructed, drawn, fondled, photographed, cast, compared, measured, revered, pondered, published, and argued over endlessly. Fossils like Lucy have become a talisman of sorts, promising to reveal the deepest secrets of our existence. In Part II the authors profile over fifty of the most significant early human fossils ever found. Each specimen is displayed in color and at actual size, most of them in multiple views. With them the authors present the cultural accoutrements associated with the fossils: stone tools which evidence increasing sophistication over time, the earliest stone, clay, and ivory art objects, and the culminating achievement of the dawn of human consciousness -- the magnificent rock and cave paintings of Europe, Africa, Australia, and the Americas.In the end From Lucy to Language is a reminder and a challenge. Like no species before us, we now seem poised to control vast parts of the planet and its life. We possess the power to influence, if not govern, evolution. For that reason, we must not forget our link to the natural world and our debt to natural selection. We need to "think deep", to add a dose of geologic time and evolutionary history to our perspective of who we are, where we came from, and where we are headed. This is the most poignant lesson this book has to offer.

    It develops an understanding of function and evolution into the discussion of anatomy of the various systems.

    As a sympathetic brain detective, Klawans deduced a great deal from his patients, not only about the immediate causes of their ailments but also about the evolutionary underpinnings of their behaviour.

    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.

    Science has seen its fair share of punch-ups over the years, but one debate, in the field of biology, has become notorious for its intensity. Over the last twenty years, Richard Dawkins and Stephen Jay Gould have engaged in a savage battle over evolution, which continues to rage even after Gould's death in 2002. Kim Sterelny moves beyond caricature to expose the real differences between the conceptions of evolution of these two leading scientists. He shows that the conflict extends beyond evolution to their very beliefs in science itself; and, in Gould?s case, to domains in which science plays no role at all.

    Now, a former Senior Editor for "Maxim gives a crash course on the men behind our favorite labels, including:

    For example, the common cold, measles, chicken pox, herpes and mumps, rubella, as well as less familiar examples, such as rabies, breakbone’ fever, hemorrhagic fevers like Ebola, and virus-induced cancers. Along the way, readers will learn about the behaviors and ultimate goals of viruses, gaining a deeper understanding of their importance in relation to the origins and the evolution of life, as well as they ways viruses have changed us at the most intimate level, to help make us quintessentially human.
