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 Nonverbal Communication in Close Relationships written by Robert J. Sternberg and published by Springer Nature. This book was released on 2022-03-15 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date compendium of knowledge on the secret language of close relationships, namely nonverbal routes of communication. In close relationships, as everyone learns sooner or later, the usefulness of words can be somewhat limited, because people (a) mean different things by the same words, (b) mean the same thing by different words, (c) sometimes find it hard to express their feelings in words, and (d) lie. Nonverbal signals therefore often provide the best means of communication. The book points out how decoding (interpreting) nonverbal signals is a major key to success, because often what people say wholly belies how they feel—nonverbal signals reveal their true feelings rather than what they want other people to think their feelings are. This book helps decode those secret signals. The book is written by the leading worldwide experts in the field of nonverbal communication to ensure accuracy, comprehensiveness, and timeliness.

Download or read book Biology of Sex written by Alex Mills and published by University of Toronto Press. This book was released on 2018-05-25 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology of Sex is a lively and intellectually challenging textbook. Mills analyzes the biological basis of sex by considering genetic, physiological, and evolutionary principles. In order to explain the biological aspects of human sex, he uses direct and intriguing comparisons with the many variations in sexual systems among non-human organisms. Text boxes provide fascinating examples: non-human species that cannibalize their partners during copulation, organisms that do not fall within one of two biological sexes, and species that “trick” others into raising their young. The author also explores questions such as: “Is sex only for reproduction?”, “Why is sex pleasurable?”, and “What are the roots of sexual conflict?” Intended primarily for readers without a science background, Biology of Sex provides novel content from the human and non-human worlds to introduce the complex subject of sex and reproduction.
Download or read book Sexual Selection And the Descent of Man written by Bernard Grant Campbell and published by Transaction Publishers. This book was released on with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just over one hundred and thirty years ago Charles Darwin, in The Descent of Man and Selection in Relation to Sex (1871), developed remarkably accurate conclusions about man's ancestry, based on a review of general comparative anatomy and psychology in which he regarded sexual selection as a necessary part of the evolutionary process. But the attention of biologists turned to the more general concept of natural selection, in which sexual selection plays a complex role that has been little understood. This volume significantly broadens the scope of modern evolutionary biology by looking at this important and long neglected concept of great importance. In this book, which is the first full discussion of sexual selection since 1871, leading biologists bring modern genetic theory and behavior observation to bear on the subject. The distinguished authors consider many aspects of sexual selection in many species, including man, within the context of contemporary evolutionary theory and research. The result is a remarkably original and well-rounded view of the whole concept that will be invaluable especially to students of evolution and human sexual behavior. The lucid authority of the contributors and the importance of the topic will interest all who share in man's perennial fascination with his own history. The book will be of central importance to a wide variety of professionals, including biologists, anthropologists, and geneticists. It will be an invaluable supplementary text for courses in vertebrate biology, theory of evolution, genetics, and physical anthropology. It is especially important with the emergence of alternative explanations of human development, under the rubric of creationism and doctrines of intelligent design. Bernard G. Campbell is professor of anthropology at the University of California, Los Angeles. Born in Weybridge, England, he received his Ph.D. from the University of Cambridge in 1957, and has been a lecturer in anthropology at Cambridge and Harvard Universities. Among his many contributions to the field of anthropology is Human Evolution: An Introduction to Man's Adaptations.
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 The Evolution of Sex written by John Maynard Smith and published by Cambridge University Press. This book was released on 1978-08-24 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of why organisms reproduce sexually is still a matter of controversy. In this account, Professor Maynard Smith considers the selective forces responsible for the origin and evolution of sexual reproduction and genetic recombination, using quantitative population genetics arguments to support his ideas. The relative importance of individual and group selection processes are also considered. the aim is to give a clear statement of the theoretical issues, and present enough of the evidence to show what kinds of facts are relevant. It is hoped that where crucial evidence is missing, experimentalists and field workers may be encouraged to collect the relevant data. The author does not claim to solve all the problems he raises, but this clear and well-argued account should provide stimulating reading for advanced undergraduate students and research workers in evolutionary theory.
Download or read book The Theory of Sex Allocation MPB 18 Volume 18 written by Eric L. Charnov and published by Princeton University Press. This book was released on 2020-03-31 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive treatment of sex allocation from the standpoint of modern evolutionary theory. It shows how the determination of sex ratio, resource allocation to sperm versus egg within simultaneous hermaphroditism, and the evolution of sex reversal can he explained as examples of a single process. The genetical theory, developed mostly with graphical arguments, also specifies when hermaphroditism and dioecy are themselves evolutionary stable. The work balances theory with field and laboratory research, providing critical tests of the theory by empirical studies of sex ratio in parasitoid wasps and mites, sex reversal in shrimp and coral reef fish, and allocation of resources to pollen versus seeds in higher plants. In addition, the author oilers an encyclopedic review of the field and laboratory work of other scientists, reviews many as yet untested hypotheses in sex allocation, and points toward numerous plant and animal systems that hold promise for future tests.
Download or read book Lost Sex written by Isa Schön and published by Springer Science & Business Media. This book was released on 2009-09-22 with total page 617 pages. 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.
Download or read book Dr Tatiana s Sex Advice to All Creation written by Olivia Judson and published by Metropolitan Books. This book was released on 2003-05-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sex guide for all living things and a hilarious natural history in the form of letters to and answers from the preeminent sexpert in all creation. Dr. Tatiana's Sex Advice to All Creation is a unique guidebook to sex. It reveals, for example, when necrophilia is acceptable and who should commit bestiality with whom. It discloses the best time to have a sex change, how to have a virgin birth, and when to eat your lover. It also advises on more mundane matters -- such as male pregnancy and the joys of a detachable penis. Entertaining, funny, and marvelously illuminating, the book comprises letters from all creatures worried about their bizarre sex lives to the wise Dr. Tatiana (a.k.a. Olivia Judson), the only sex columnist in creation with a prodigious knowledge of evolutionary biology. Fusing natural history with advice to the lovelorn, blending wit and rigor, she is able to reassure her anxious correspondents that although the acts they describe might sound appalling and unnatural, they are all perfectly normal -- so long as you are not a human. In the process, she explains the science behind it all, from Darwin's theory of sexual selection to why sexual reproduction exists at all. Applying human standards to the natural world, in the end she reveals the wonders of both. "Delightful . . . Easy to understand and hard to resist, it's sex education at its prime -- accurate, comprehensive, and hilarious." -- Newsweek
Download or read book The Mating Mind written by Geoffrey Miller and published by Anchor. This book was released on 2011-12-21 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: At once a pioneering study of evolution and an accessible and lively reading experience, a book that offers the most convincing—and radical—explanation for how and why the human mind evolved. Consciousness, morality, creativity, language, and art: these are the traits that make us human. Scientists have traditionally explained these qualities as merely a side effect of surplus brain size, but Miller argues that they were sexual attractors, not side effects. He bases his argument on Darwin’ s theory of sexual selection, which until now has played second fiddle to Darwin’ s theory of natural selection, and draws on ideas and research from a wide range of fields, including psychology, economics, history, and pop culture. Witty, powerfully argued, and continually thought-provoking, The Mating Mind is a landmark in our understanding of our own species.
