Book excerpt: This work is chiefly devoted to the description and discussion of a large collection of Paleocene mammals, from the Fort Union of central Montana, belonging to the United States National Museum. The first part is geological, chiefly stratigraphic and paleontological. The location and general characteristics of the mammal-bearing area are described, followed by a resume of its stratigraphy and and geologic structure. The second and longer part is zoological and is devoted to definitions of all taxonomic groups which were originally described from this field or the conception of which is markedly affected by material from here, to discussion of the relationships and phylogeny of the mammals represented, and to description of the specimens in the collection. United States National Museum catalog numbers are included in descriptions.

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.

Download or read book Phylogeny of the Primates written by W. Luckett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has witnessed a tremendous surge of interest in varied aspects of primate biology, encompassing virtually all disciplines of the biological sciences. Regardless of whether these studies have been approached from a paleontological, morphological, developmental, biochemical, neuroanatomical, or behavioral point of view, one under lying theme has been a common interest in the possible phylogenetic relationships suggested by the results of such studies. In some cases, sound taxonomic principles have not been followed in the interpretation of these data, and this has led to skepticism among many taxonomists with regard to the validity of some of the genealogical relationships and conclusions suggested by comparative studies of living primates. It is generally agreed that the fossil record alone provides the essential time dimension for directly observing changes in characteristics, but unfortunately this record is limited both in the number of genera represented and particularly in the incomplete nature of the available preserved material. On the other hand, extensive comparative analyses of numerous characteristics in living primates have provided additional insight into possible phylogenetic relationships, despite the lack of a time dimension. Such studies of both fossil and living primates are enhanced considerably by a cladistic analysis of the probable primitive (ancestral) or advanced (derived) condition of each character state discussed, based upon their distribution (and ontogeny, wherever possible) in a wide variety of primate and nonprimate taxa, including other eutherian mammals, marsupials, mono tremes, and reptiles.

Available in PDF, EPUB and Kindle. Book excerpt: This study reproduces one "Report of Meetings" & six "Bulletins" from the Committee on Common Problems of Genetics, Paleontology, & Systematics. This Committee operated as an administrative unit of the National Research Council, part of the U.S. Nat. Acad. of Science. It was launched in 1943, blossomed for two years, then served as a cornerstone for other cooperative projects. The Committee provided a crucial foothold for those seeking a synthetics view of evolution in 1940s America. These forgotten documents show the Committee at work: building coalitions, defining priorities, & negotiating a common vision. They also show factions within the Committee competing for the leadership of this emerging community. Photo.

Download or read book The Paleobiological Revolution written by David Sepkoski and published by University of Chicago Press. This book was released on 2009-10-15 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Paleobiological Revolution chronicles the incredible ascendance of the once-maligned science of paleontology to the vanguard of a field. With the establishment of the modern synthesis in the 1940s and the pioneering work of George Gaylord Simpson, Ernst Mayr, and Theodosius Dobzhansky, as well as the subsequent efforts of Stephen Jay Gould, David Raup, and James Valentine, paleontology became embedded in biology and emerged as paleobiology, a first-rate discipline central to evolutionary studies. Pairing contributions from some of the leading actors of the transformation with overviews from historians and philosophers of science, the essays here capture the excitement of the seismic changes in the discipline. In so doing, David Sepkoski and Michael Ruse harness the energy of the past to call for further study of the conceptual development of modern paleobiology.
Download or read book Aristotle s Ladder Darwin s Tree written by J. David. Archibald and published by Columbia University Press. This book was released on 2014-07-15 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading paleontologist David Archibald explores the rich history of visual metaphors for biological order from ancient times to the present and their influence on human beingsÕ perception of their place in nature. Specifically, Archibald focuses on ladders and trees, and the first appearance of trees to represent seasonal life cycles. Their use in ancient Roman decorations and genealogies was then appropriated by the early Christian Church to represent biblical genealogies. The late eighteenth century saw the idea of a tree reappropriated to visualize relationships in the natural world, sometimes with a creationist view, but in some instances suggesting evolution. Charles DarwinÕs On the Origin of Species (1859) exorcised the exclusively creationist view of the Òtree of life.Ó His ideas sparked an explosion of trees, mostly by younger acolytes in Europe. Although DarwinÕs influence waned in the early twentieth century, by midcentury his ideas held sway once again in time for another and even greater explosion of tree building, generated by the development of new theories on how to assemble trees, the birth of powerful computing, and the emergence of molecular technology. Throughout his far-reaching study, and with the use of many figures, Archibald connects the evolution of Òtree of lifeÓ iconography to our changing perception of the world and ourselves, offering uncommon insight into how we went from standing on the top rung of the biological ladder to embodying just one tiny twig on the tree of life.
