Book Description
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).

Book Description
This text provides an elementary level discussion of recent theory relating to the evolutionary and adaptive aspects of reproductive behaviour. The relation between ultimate and proximate levels of explanation is the major theme of the book. Two new chapters in this edition incorporate findings from recent research and there is also new material on humans, physiology, and development. Sex and reproductive behaviour are examined from an evolutionary comparative perspective and numerous empirical studies and examples are cited.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Geary (psychology and anthropology, U. of Missouri-Columbia) thinks culturally constructed gender roles alone cannot account for the differences in the social behavior of men and women. He turns to Darwin's theory of sexual selection as the best avenue for understanding. His main focus is how th etwo elements of competition between males and of females selecting mates has influenced human behavior over the centuries and across cultures.

Book Description
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.

Book Description
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.
