Available in PDF, EPUB and Kindle. Book excerpt: Few things come more naturally to us than sex—or so it would seem. Yet to a chimpanzee, the sexual practices and customs we take for granted would appear odd indeed. He or she might wonder why we bother with inconveniences like clothes, why we prefer to make love on a bed, and why we fuss so needlessly over privacy. Evolution and Human Sexual Behavior invites us into the thought-experiment of imagining human sex from the vantage point of our primate cousins, in order to underscore the role of evolution in shaping all that happens, biologically and behaviorally, when romantic passions are aroused. Peter Gray and Justin Garcia provide an interdisciplinary synthesis that draws on the latest discoveries in evolutionary theory, genetics, neuroscience, comparative primate research, and cross-cultural sexuality studies. They are our guides through an exploration of the patterns and variations that exist in human sexuality, in chapters covering topics ranging from the evolution of sex differences and reproductive physiology to the origins of sexual play, monogamous unions, and the facts and fictions surrounding orgasm. Intended for generally curious readers of all stripes, this up-to-date, one-volume survey of the evolutionary science of human sexual behavior explains why sexuality has remained a core fascination of human beings throughout time and across cultures.

Available in PDF, EPUB and Kindle. Book excerpt: Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.

Available in PDF, EPUB and Kindle. Book excerpt: Darwins Secret Sex Problem What Darwin Ignored . . . For all his revolutionary insight into the fascinating processes of evolution so useful to current scientific research, health care, and technology, Darwin never seriously confronted the crucial, insurmountable gap in his grand theory between asexual replication and sexual reproduction. Nor could Darwins famed natural selection have provided simultaneous on-time delivery of the first male/female pair of millions of sexually unique species required for evolutions bedrock premise of common descenta fundamental flaw fatal to the romanticized microbe-to-man Evolution Story. Darwins Secret Sex Problem is a witty, engaging, scientifically sound exploration of perhaps the greatest secret of sexualitythe utter inability of Darwinian evolution to explain its origin (John E. Silvius, PhD, Senior Professor Emeritus of Biology, Cedarville University). I highly recommend this book by F. LaGard Smith, a nonspecialist whose careful research demonstrates that he understands the crucial issues surrounding evolutions fatal sex problem, and who has a remarkable ability to communicate complex concepts to a broad audience (Geoff Barnard, PhD, MA, retired Reproductive Endocrinologist and Cambridge University Research Scientist).

Available in PDF, EPUB and Kindle. Book excerpt: A noteworthy investigation of the Darwinian element in American fiction from the realist through the Freudian eras. theories of sexual selection and of the emotions are essential elements in American fiction from the late 1800s through the 1950s, particularly during the Freudian era and the years surrounding the Scopes trial. the Sex Problem, and what resulted was a great diversity of American narratives aligned with either Darwinian or a number of anti-Darwinian theories of evolution. Included are intriguing discussions of works by Frank Norris, Jack London, Stephen Crane, Theodore Dreiser, Gertrude Stein, Willa Cather, Sherwood Anderson, F. Scott Fitzgerald, five writers of the Harlem Renaissance, John Steinbeck, and Ernest Hemingway. Among the ideas explored are Darwin's theory of common descent; the question of man's place in nature; the possibility of evolutionary progress; the issues of heredity and eugenics; the Darwinian basis of Freud's theory of sexual repression; the quandary of male violence and the role of female choice in sexual selection; the power of and the problems o rracial and sexual selection; the power of and the problems of racial and sexual difference; and the ecological problems that arose directly from Darwin's theory of evolution. America's major narratives of human life and love and will be appreciated by literary scholars and readers interested in Darwinism and culture.
Download or read book Evolution and Gender written by Rosemary L. Hopcroft and published by Routledge. This book was released on 2015-12-22 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offering new research and analysis on the relation between gender and evolution, this book explains conflict between the sexes and the frequent emergence and stubborn continuation of patriarchal regimes that serve to control the behavior of women in societies around the world, both past and present. Women and men are different, on average. But that does not mean they are unequal. Indeed, understanding average differences is key to the full realization of equality in health care and other dimensions of social life. Hopcroft shows that gender differences in physiology, psychology, and behavior can be traced to slight differences in evolved traits between men and women. These differences exist because of sex differences in investment in offspring, which meant that, in the environment of evolution, some adaptive problems were more important for men to solve than for women, and vice versa. For men, the most important adaptive problem to solve was that of finding a mate. Men who did not solve this problem are not our ancestors. For women, the most important adaptive problem to solve was that of successfully bearing and raising children. Women who did not solve this problem are not our ancestors. These small differences underlie all the differences described in the book, including sex differences in mate preferences, physiology, cognition, aggression, status striving, and emotional experience. It can also help explain the differential treatment of children by parents, the differential success of boys and girls in modern schools, and sex differences in style of communication.

This book was released on 2020-03-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the relationship between various types of reproduction and the evolutionary process. Starting with the concept of meiosis, George C. Williams states the conditions under which an organism with both sexual and asexual reproductive capacities will employ each mode. He argues that in low-fecundity higher organisms, sexual reproduction is generally maladaptive, and persists because there is no ready means of developing an asexual alternative. The book then considers the evolutionary development of diverse forms of sexuality, such as anisogamy, hermaphroditism. and the evolution of differences between males and females in reproductive strategy. The final two chapters examine the effect of genetic recombination on the evolutionary process itself.

Download or read book Eros And Evolution written by Richard E Michod and published by Addison Wesley Publishing Company. This book was released on 1995-01-20 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bee lands on a blossom, a stag rears back his head in bellowing, a human couple lies exhausted in passionate embrace. The flower, the deer, the human, even the unseen virus - they all must have sex. But why? When we think of sex, we may think of the pleasure and pain it causes us. But there is a more fundamental problem of sex. It is the unresolved question of why sex exists at all. What are the consequences of sex that make it so important to us and so widespread in nature? The answer to this question lies not in our own attitudes and feelings about sex, but deep in our evolutionary past. Why did sex evolve as the means for reproduction for many species? Sex requires a huge commitment of time, energy, and resources, and it can even be physically dangerous. Sex is not the only path to reproduction - simple life forms do not practice sexual mating; offspring are produced by simple cell division. There are examples of higher life forms that practice asexual reproduction, in which the female reproduces alone. "Why sex?" is a question that was first raised by Charles Darwin in his Origin of the Species, and the answer has eluded biologists for over a century. In Eros and Evolution Richard Michod, a leading evolutionary biologist, begins his exploration into this question by pointing out the fatal flaws in the widely accepted "variation view", that sex is necessary for producing more diverse offspring than could be produced asexually. Chief among those flaws is the fact that sex undoes what it creates, producing a beneficial new combination of genes in one generation only to break it apart in the next. Michod argues that genetic variation and reproduction of organisms are side effects butnot the sole purpose of sex. According to his revolutionary theory, sex has a more far-reaching mission: to repair and overcome the genetic errorsdamages and mutations - that threaten life. With lucid explanations and intriguing excursions into our evolutionary past, this book shows how sex maintains the well-being of genes and in so doing, provides for the immortality of life itself. Yet, why sex exists is only part of the fascinating story in Eros and Evolution. This book also considers why it matters that sex exists. Michod deconstructs Darwin to explore such questions as "Why are there species?" and "Do organisms - as wonderfully designed as they are - really matter in evolution, or are they merely vehicles for the perpetuation of genes?" In the process he shows how what began as a necessary but mechanical process of gene repair has ended up forever changing the landscape of the living world.

Download or read book Sex Time and Power written by Leonard Shlain and published by Penguin. This book was released on 2004-08-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in the bestselling The Alphabet Versus the Goddess, Leonard Shlain’s provocative new book promises to change the way readers view themselves and where they came from. Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female’s pelvis and the increasing size of infants’ heads precipitated a crisis for the species. Natural selection allowed for the adaptation of the human female to this environmental stress by reconfiguring her hormonal cycles, entraining them with the periodicity of the moon. The results, however, did much more than ensure our existence; they imbued women with the concept of time, and gave them control over sex—a power that males sought to reclaim. And the possibility of achieving immortality through heirs drove men to construct patriarchal cultures that went on to dominate so much of human history. From the nature of courtship to the evolution of language, Shlain’s brilliant and wide-ranging exploration stimulates new thinking about very old matters.
Download or read book The Masterpiece of Nature written by Graham Bell and published by Routledge. This book was released on 2019-11-28 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, The Masterpiece of Nature examines sex as representative of the most important challenge to the modern theory of evolution. The book suggests that sex evolved, not as the result of normal Darwinian processes of natural selection, but through competition between populations or species - a hypothesis elsewhere almost universally discredited. The book also discusses the nature of sex and its consequences for the individual and for the population, as well as various other theories of sex. Since the value of these theories is held to reside wholly in their ability to predict the patterns of sexuality observed in nature, the book seeks to provide an extensive review of the circumstances in which sexuality is attenuated or lost throughout the animal kingdom, and these facts are then used to weigh up the merits of the rival theories. This book will be of interest to researchers in the area of genetics, ecology and evolutionary biology.
Download or read book Evolution s Rainbow written by Joan Roughgarden and published by Univ of California Press. This book was released on 2013-09-14 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality. Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.
