This book was released on 2013-03-09 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnivores have always fascinated us, even though they make up only 10% of all mammalian genera and only about 2% of all mammalian biomass. In Greek mythology most of the gods adorned their robes and helmets with depictions of carnivores, and the great hero Hercules' most famous feat was killing the "invulnerable" lion with his bare hands. Part· of our fascination with carnivores stems from fright and intrigue, and sometimes even hatred because of our direct competition with them. Cases of "man-eating" lions, bears, and wolves, as well as carnivores' reputation as killers of livestock and game, provoke communities and governrpents to adopt sweeping policies to exterminate them. Even President Theodore Roosevelt, proclaimer of a new wildlife protectionism, described the wolf as "the beast of waste and desolation. " The sheer presence and power of carnivores is daunt ing: they can move quickly yet silently through forests, attaining rapid bursts of speed when necessary; their massive muscles are aligned to deliver powerful attacks, their large canines and strong jaws rip open carcasses, and their scis sor-like carnassials slice meat. Partly because of our fear of these attributes, trophy hunting of carnivores has been, and to a certain extent still is, a sign of bravery and skill. Among some Alaskan Inuit, for example, a man is not eligible for marriage until he has killed a succession of animals of increasing size and dangerousness, culminating with the most menacing, the polar bear.
Download or read book Fossil Vertebrates of Greece Vol 2 written by Evangelos Vlachos and published by Springer Nature. This book was released on 2021-10-23 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2-volume set provides a state-of-the-art study of the fossil record and taxonomy of the main vertebrate groups from Greece. Greece stands between 3 continents and its vertebrate fossil record is of great importance for paleontological and evolutionary studies in Europe, Asia and Africa. Fossils from classic, world-famous localities (e.g., Pikermi, Samos) form an essential part of the collections of the most important museums in the world and have been studied by numerous scientists. Recent paleontological research led to the discovery and study of numerous new sites. The volumes contain a taxonomic review of all named and identified taxa, their taxonomic history and current status, as well as historical, phylogenetic and biogeographic information. Volume 2 contains a synopsis of the fossil record and taxonomy of important groups of mammals represented in the fossil record of Greece. The volume starts with specific chapters on laurasiatherians like insectivores and bats, moving on to the main part of the book that deals with three of the most important fossil groups in the country. The fossil record of even-toed animals is summarized with chapters on bovids, cervids, suoids, anthracotheres, hippos, giraffes, and tragulids. The fossil record of odd-toed animals is presented with special chapters on horses, tapirs, rhinos, and chalicotheres. The last part of this volume deals with meat-eating, carnivoran groups, like felids, viverrids, hyaenas, canids, bears, ailurids, mephitids and mustelids. The volume ends with a special chapter on insular endemic mammals from the various islands of Greece.

Available in PDF, EPUB and Kindle. Book excerpt: More than 99% of all life that has ever existed on this planet is extinct. Moreover, human acceleration of the extinction of species has created a crisis in biodiversity. How can the history of past life be retreived? How does this history bear on our understanding of the organization and evolution of present-day species? These questions are addressed in extinction and phylogeny.

Download or read book Timetrees Incorporating Fossils and Molecules 2nd edition written by Michel Laurin and published by Frontiers Media SA. This book was released on 2022-09-15 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calibrating phylogenies to time is central to addressing many questions in evolutionary biology and macroevolution. The fossil record once provided our only source for establishing a timeline for evolution. However, the incompleteness of the fossil record and the non-uniformity of fossil recovery rate make it challenging to obtain precise estimates of divergence times from fossil evidence alone. Molecular dating, which combines evidence from the geological and molecular records, enables us to generate a much more complete and precise timeline of events. The molecular clock can be time-calibrated using temporal evidence from fossils and used to estimate divergence times based on the assumption that the rate of sequence evolution will be approximately constant over time and among lineages. Methodological challenges to applying this concept in practice have been to relax the assumption of constant evolutionary rates and to model the uncertainty associated with paleontological and geological calibrations. To this end, available statistical methods have become increasingly complex in order to capture key features of empirical data. These are typically applied using Bayesian inference, which provides a powerful framework for incorporating multiple sources of uncertainty. Although overall more effort has been expended in developing models of molecular sequence evolution, critical advances have also included approaches to modeling taxonomic diversification and fossilization. In particular, recent advances in birth-death process models have allowed for continuous sampling along lineages, enabling more information from the fossil record to be incorporated into dating analyses in a statistically coherent way. In addition, available dating methods can now be applied to scenarios in which no molecular data may be available, allowing for novel insights into the evolution of entirely extinct clades. Other recent innovations enable us to date divergence times among taxa that have no fossil record, including the use of gene duplication events or biogeographic evidence. Furthermore, time-calibrated trees are necessary for obtaining phylogenetic estimates of taxonomic diversification and extinction rates, which can now be jointly inferred along with lineage divergence times. These approaches offer an exciting opportunity to understand the evolution of life in deep time, although key challenges remain, especially with regards to modeling the processes of genome evolution, taxonomic diversification and fossil recovery. In this Research Topic, we focus on recent advances in methodology, outstanding challenges, and the application of molecular and paleontological dating methods to empirical case studies across the Tree of Life.
Download or read book Testing Scientific Theories written by John Earman and published by U of Minnesota Press. This book was released on 1983 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Testing Scientific Theories was first published in 1984. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Since much of a scientist's work consists of constructing arguments to show how experiments and observation bear on a particular theory, the methodologies of theory testing and their philosophical underpinnings are of vital concern to philosophers of science. Confirmation of scientific theories is the topic of Clark Glymour's important book Theory and Evidence,published in 1980. His negative thesis is that the two most widely discussed accounts of the methodology of theory testing - hypothetico-deductivism and Bayesianism - are flawed. The issues Glymour raises and his alternative "bootstrapping" method provided the focus for a conference sponsored by the Minnesota Center for Philosophy of Science and for this book. As editor John Earman says in his preface, the papers presented in Testing Scientific Theories germinate so many new ideas that philosophers of science will reap the harvest for years to come. Topics covered include a discussion of Glymour's bootstrapping theory of confirmation, the Bayesian perspective and the problems of old evidence, evidence and explanation, historical case studies, alternative views on testing theories, and testing particular theories, including psychoanalytic hypotheses and hypotheses about the completeness of the fossil record.
