Available in PDF, EPUB and Kindle. Book excerpt: “[A] deliciously written account of the evolution of sex, in all of its bizarre manifestations” by a noted paleontologist—"Read, blush, and enjoy!” (Jared Diamond, author of Guns, Germs, and Steel). We all know about the birds and the bees, but what about the ancient placoderm fishes and the dinosaurs? In 2008, paleontologist John A. Long and a team of researchers announced their discovery of a 380-million-year-old placoderm fish fossil, known as “the mother fish,” which revealed the earliest known example of internal fertilization. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction, or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on a lively tour through the sex lives of ancient fish and the unusual mating habits of arthropods, tortoises, and even a well-endowed Argentine Duck. Long discusses these discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance.
Download or read book Sex in Cetaceans written by Bernd Würsig and published by Springer Nature. This book was released on 2023-09-25 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex in Cetaceans provides an up-to-date review of multi-faceted aspects related to mating and reproduction in toothed and baleen whales. This open access book begins with discussions of sexual selection and anatomical traits related to mating and diversity between the sexes. The functions of non-conceptive copulations are reviewed as are different research techniques applied to explore sex in cetaceans. Authors and editors build knowledge of female and male social, mating, and parental strategies and tactics for several specific toothed dolphin/porpoise/whale species and baleen whale species. It concludes with a discussion of potential conservation efforts and ways to help especially beleaguered species and populations the world over. The volume is intended as a major primer of cetacean sex for undergraduate and graduate students, new and established researchers in the field, and the public wishing to learn more.
Download or read book The Differences Between the Sexes written by R. V. Short and published by Cambridge University Press. This book was released on 1994-08-04 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most animals, from bees to bison, house flies to humans, it is possible to see at a glance whether an individual is male or female. How and why have these differences in appearance and behaviour developed and what are the nature and extent of the differences between men and women? This book reviews the latest molecular, genetic, hormonal, anatomical and behavioural data in a wide range of species in a series of lively and highly readable articles from the world's leading experts in this field. Such an overview has never before been attempted. It will have a wide appeal, especially to undergraduates and graduates in the biological and medical sciences, and will help to bridge the gap between those who study genes and molecules in the laboratory and those who study the behaviour of animals in the wild.
Download or read book Sex and Gender Hierarchies written by Barbara D. Miller and published by Cambridge University Press. This book was released on 1993-02-18 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited collection attempts to revive a unified anthropological approach to the study of sex and gender hierarchies. Seventeen distinguished contributors - from cultural anthropology, physical anthropology, archaeology, and anthropological linguistics - have produced a wealth of fascinating data on human and primate, ancient and contemporary, and 'primitive' and developed societies, covering topics such as mothering and child care, work, health, intrafamily relationships, and public power. The interdisciplinary approach successfully contributes to the development of better theory and methodology in anthropology.

Available in PDF, EPUB and Kindle. Book excerpt: A practical and fun identification manual for amateurs and professionals alike "Provides the beginning fossil vertebrate enthusiast with some valuable information about the fossils they are collecting."--Guy "Harley" Means, Florida Geological Survey "Illustrates how the dynamic story of ancient life and death and post-mortem utilization is accessible from the study of bone shapes. It is this very thing that made me want to be a paleontologist in the first place."--Pennilyn Higgins, University of Rochester Written primarily for the avid amateur and beginning paleontologist, What Your Fossils Can Tell You offers both experienced and novice fossil hunters and collectors the information needed to correctly identify and interpret the significance of their discoveries. Professionals in the field may also use this book as a pictorial resource to assist them in bridging the fields of pathology and archaeology as they relate to paleontology. Amateur fossil hunters are presented with the tools they need to recognize significant finds and knowledge of how to collect vertebrate fossils responsibly and legally. Robert Sinibaldi, in informal collaboration with a number of fossil experts, has compiled materials with a wide appeal. He explains many of the complex bumps, grooves, markings, and other anomalies that occur on fossil bones and teeth. A wealth of photographs helps readers visually identify these features and apply related concepts to their personal collections. Along with many common specimens, scores of unique fossil items appear here in print for the first time.

Download or read book Shaping Primate Evolution written by Fred Anapol and published by Cambridge University Press. This book was released on 2004-05-20 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shaping Primate Evolution is an edited collection of papers about how biological form is described in primate biology, and the consequences of form for function and behavior. The contributors are highly regarded internationally recognized scholars in the field of quantitative primate evolutionary morphology. Each chapter elaborates upon the analysis of the form-function-behavior triad in a unique and compelling way. This book is distinctive not only in the diversity of the topics discussed, but also in the range of levels of biological organization that are addressed from cellular morphometrics to the evolution of primate ecology. The book is dedicated to Charles E. Oxnard, whose influential pioneering work on innovative metric and analytic techniques has gone hand-in-hand with meticulous comparative functional analyses of primate anatomy. Through the marriage of theory with analytical applications, this volume will be an important reference work for all those interested in primate functional morphology.

This book was released on 2013-12-18 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: A world of categones devmd of spirit waits for life to return. Saul Bellow, Humboldt's Gift The stock-in-trade of communicating hypotheses about the historical path of evolution is a graphical representation called a phylogenetic tree. In most such graphics, pairs of branches diverge from other branches, successively marching across abstract time toward the present. To each branch is tied a tag with a name, a binominal symbol that functions as does the name given to an individual human being. On phylogenetic trees the names symbolize species. What exactly do these names signify? What kind of information is communicated when we claim to have knowledge of the following types? "Tetonius mathewzi was ancestral to Pseudotetonius ambiguus. " "The sample of fossils attributed to Homo habzlis is too variable to contain only one species. " "Interbreeding populations of savanna baboons all belong to Papio anubis. " "Hylobates lar and H. pileatus interbreed in zones of geographic overlap. " While there is nearly universal agreement that the notion of the speczes is fundamental to our understanding of how evolution works, there is a very wide range of opinion on the conceptual content and meaning of such particular statements regarding species. This is because, oddly enough, evolutionary biolo gists are quite far from agreement on what a species is, how it attains this status, and what role it plays in evolution over the long term.
