Available in PDF, EPUB and Kindle. Book excerpt: This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.

This book was released on 2020-03-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution of the horse has been an often-cited primary example of evolution, as well as one of the classic and important stories in paleontology for over a century and a half, due to their rich fossil record across 5 continents: North America, South America, Europe, Asia and Africa. The recent horse has served a profound role in human ancestry, including agriculture, commerce, sport, transport, warfare, and in prehistory, for the subsistence of humans. Many studies have examined the evolution of the Equidae and chronicled the striking changes in skulls, dentition, limbs, and body size which have long been perceived to be a response to environmental shifts through time. Most comprehensive studies heretofore have: (1) focused on the “Great Transformation”- changes that occurred in the early Miocene, (2) involved tracking long-term diversity or paleoecological trends on a single continent or within a geographical locality, or (3) concentrated on the 3-toed hipparions. The Plio–Pleistocene evolutionary stage of horse evolution is punctuated by the great climatic fluctuations of the Quaternary beginning 2.6 Ma which influenced Equus evolution, biogeographic dispersion and adaptation on a nearly global scale. The evolutionary biology of Equus evolution across its entire range remains relatively poorly understood and often highly controversial. Some of this lack of understanding is due to assumptions that have arisen because of the relatively derived craniodental and postcranial anatomy of Equus and its close relatives which has seemed to imply that that these forms occupied relatively homogenous and narrow dietary and locomotor niches - notions that have not been adequately addressed and rigorously tested. Other challenges have revolved around teasing apart environmentally-driven adaptation versus phylogenetically defined morphological change. Geochronologic age control of localities, geographic provinces and continents has improved, but in no way is absolute and can be reexamined in our proposed volume. Temporal resolution for paleodietary, paleohabitat and paleoecological interpretations are also challenging for understanding the evolution of Equus. Our proposed volume attempts to assemble a group of experts who will address multiple dimensions of Equus’ evolution in time and space.

This book was released on 2021-01-01 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This work was described, on its first appearance, by a writer in the Quarterly Review as "One of the most interesting narratives of voyaging that it has fallen to our lot to take up, and one which must always occupy a distinguished place in the history of scientific navigation. [...] Most of the views given in this work are from sketches made on the spot by Mr. Pritchett, with Mr. Darwin's book by his side. Some few of the others are taken from engravings which Mr. Darwin had himself selected for their interest as illustrating his voyage, and which have been kindly lent by his son." -Preface by John Murray

Download or read book The Origin of Species and The Voyage of the Beagle written by Charles Darwin and published by Everyman's Library. This book was released on 2012-08-15 with total page 1034 pages. Available in PDF, EPUB and Kindle. Book excerpt: Easily the most influential book published in the nineteenth century, Darwin’s The Origin of Species is also that most unusual phenomenon, an altogether readable discussion of a scientific subject. On its appearance in 1859 it was immediately recognized by enthusiasts and detractors alike as a work of the greatest importance: its revolutionary theory of evolution by means of natural selection provoked a furious reaction that continues to this day. The Origin of Species is here published together with Darwin’s earlier Voyage of the ‘Beagle.’ This 1839 account of the journeys to South America and the Pacific islands that first put Darwin on the track of his remarkable theories derives an added charm from his vivid description of his travels in exotic places and his eye for the piquant detail.
Download or read book Horse Nations written by Peter Mitchell and published by OUP Oxford. This book was released on 2015-03-26 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Native American on a horse is an archetypal Hollywood image, but though such equestrian-focused societies were a relatively short-lived consequence of European expansion overseas, they were not restricted to North America's Plains. Horse Nations provides the first wide-ranging and up-to-date synthesis of the impact of the horse on the Indigenous societies of North and South America, southern Africa, and Australasia following its introduction as a result of European contact post-1492. Drawing on sources in a variety of languages and on the evidence of archaeology, anthropology, and history, the volume outlines the transformations that the acquisition of the horse wrought on a diverse range of groups within these four continents. It explores key topics such as changes in subsistence, technology, and belief systems, the horse's role in facilitating the emergence of more hierarchical social formations, and the interplay between ecology, climate, and human action in adopting the horse, as well as considering how far equestrian lifestyles were ultimately unsustainable.
