Book Synopsis Cetacean Paleobiology by : Felix G. Marx
Download or read book Cetacean Paleobiology written by Felix G. Marx and published by John Wiley & Sons. This book was released on 2016-05-31 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans throughout history. Their mammalian affinities have been long recognized, but exactly which group of terrestrial mammals they descend from has, until recently, remained in the dark. Recent decades have produced a flurry of new fossil cetaceans, extending their fossil history to over 50 million years ago. Along with new insights from genetics and developmental studies, these discoveries have helped to clarify the place of cetaceans among mammals, and enriched our understanding of their unique adaptations for feeding, locomotion and sensory systems. Their continuously improving fossil record and successive transformation into highly specialized marine mammals have made cetaceans a textbook case of evolution - as iconic in its own way as the origin of birds from dinosaurs. This book aims to summarize our current understanding of cetacean evolution for the serious student and interested amateur using photographs, drawings, charts and illustrations.
Book Synopsis The Beginning of the Age of Mammals by : Kenneth D. Rose
Download or read book The Beginning of the Age of Mammals written by Kenneth D. Rose and published by JHU Press. This book was released on 2006-10-31 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of G. G. Simpson's classic work, Kenneth D. Rose's The Beginning of the Age of Mammals analyzes the events that occurred directly before and after the mysterious K-T boundary which so quickly thrust mammals from obscurity to planetary dominance. Rose surveys the evolution of mammals, beginning with their origin from cynodont therapsids in the Mesozoic, contemporary with dinosaurs, through the early Cenozoic, with emphasis on the Paleocene and Eocene adaptive radiations of therian mammals. Focusing on the fossil record, he presents the anatomical evidence used to interpret behavior and phylogenetic relationships. The life's work of one of the most knowledgeable researchers in the field, this richly illustrated, magisterial book combines sound scientific principles and meticulous research and belongs on the shelf of every paleontologist and mammalogist.

Book Synopsis Mammals: A Very Short Introduction by : T. S. Kemp
Download or read book Mammals: A Very Short Introduction written by T. S. Kemp and published by Oxford University Press. This book was released on 2017-09-21 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a modest beginning in the form of a little shrew-like, nocturnal, insect eating ancestor that lived 200 million years ago, mammals evolved into the huge variety of different kinds of animals we see today. Many species are still small, and follow the lifestyle of the ancestor, but others have adapted to become large grazers and browsers, like the antelopes, cattle, rhinos, and elephants, or the lions, hyaenas, and wolves that prey upon them. Yet others evolved to be specialist termite eaters able to dig into the hardest mounds, or tunnel creating burrowers, and a few took to the skies as gliders and the bats. Many live partly in the water, such as otters, beavers, and hippos, while whales and dugongs remain permanently in the seas, incapable of ever emerging onto land. In this Very Short Introduction T. S. Kemp explains how it is a tenfold increase in metabolic rate - endothermy or "warm-bloodedness" - that lies behind the high levels of activity, and the relatively huge brain associated with complex, adaptable behaviour that epitomizes mammals. He describes the remarkable fossil record, revealing how and when the mammals gained their characteristics, and the tortuous course of their subsequent evolution, during which many bizarre forms such as sabre-toothed cats, and 30-tonne, 6-m high browsers arose and disappeared. Describing the wonderful adaptations that mammals evolved to suit their varied modes of life, he also looks at those of the mainly arboreal primates that culminated ultimately in Homo sapiens. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Synopsis Great Transformations in Vertebrate Evolution by : Kenneth P. Dial
Download or read book Great Transformations in Vertebrate Evolution written by Kenneth P. Dial and published by University of Chicago Press. This book was released on 2015-07-20 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did flying birds evolve from running dinosaurs, terrestrial trotting tetrapods from swimming fish, and whales return to swim in the sea? These are some of the great transformations in the history of life; events that have captured the imagination of scientists and the general public alike. At first glance, these major evolutionary events seem utterly impossible. The before and after look so fundamentally different that the great transformations of the history of life not only seem impossible, but unknowable. The 500 million year history of vertebrates is filled with change and, as a consequence, every living species contains within its structure, DNA, and fossil record, a narrative of them. A battery of new techniques and approaches, from diverse fields of inquiry, are now being marshaled to explore classic questions of evolution. These approaches span multiple levels of biological organization, from DNA sequences, to organs, to the physiology and ecology of whole organisms. Analysis of developmental systems reveals deep homologies of the mechanisms that pattern organs as different as bird wings and fish fins. Whales with legs are one of a number of creatures that tell us of the great transformations in the history of life. Expeditions have discovered worms with a kind of head, fishes with elbows, wrists, and necks; feathered dinosaurs, and human precursors to name only a few. Indeed, in the last 20 years, paleontologists have discovered more creatures informative of evolutionary transitions than in the previous millennium. "The Great Transformations "captures the excitement of these new discoveries by bringing diverse teams of renowned scientists together to attack particular transformations, and to do so in a contents organized by body part--head, neck, fins, limbs, and then the entire bauplan. It is a work that will transform evolutionary biology and paleontology."
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.
Book Synopsis At the Water's Edge by : Carl Zimmer
Download or read book At the Water's Edge written by Carl Zimmer and published by Simon and Schuster. This book was released on 2014-08-26 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everybody Out of the Pond At the Water's Edge will change the way you think about your place in the world. The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.
Book Synopsis The Evidence for Evolution by : Alan R. Rogers
Download or read book The Evidence for Evolution written by Alan R. Rogers and published by University of Chicago Press. This book was released on 2011-06-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to polling data, most Americans doubt that evolution is a real phenomenon. And it’s no wonder that so many are skeptical: many of today’s biology courses and textbooks dwell on the mechanisms of evolution—natural selection, genetic drift, and gene flow—but say little about the evidence that evolution happens at all. How do we know that species change? Has there really been enough time for evolution to operate? With The Evidence for Evolution, Alan R. Rogers provides an elegant, straightforward text that details the evidence for evolution. Rogers covers different levels of evolution, from within-species changes, which are much less challenging to see and believe, to much larger ones, say, from fish to amphibian, or from land mammal to whale. For each case, he supplies numerous lines of evidence to illustrate the changes, including fossils, DNA, and radioactive isotopes. His comprehensive treatment stresses recent advances in knowledge but also recounts the give and take between skeptical scientists who first asked “how can we be sure” and then marshaled scientific evidence to attain certainty. The Evidence for Evolution is a valuable addition to the literature on evolution and will be essential to introductory courses in the life sciences.
