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.
The horse has frequently been used as a classic example of long-term evolution because it possesses an extensive fossil record. This book synthesizes the large body of data and research relevant to an understanding of fossil horses from perspectives such as biology, geology, paleontology.
Origins: Speak to the Earth is an anthology of scientific evidence supporting a creation / global flood / young earth worldview. It is written primarily for students as an alternative to the theory of evolution. God himself formed the earth and made it; he hath established it, he did not create it a waste place [he created it not in vain], he formed it to be inhabited. (Isaiah 45:18)
"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
Darwin's notes from his 1831 trip provide an account of the HMS "Beagle" and the first hints of his theory of evolution and natural selection.
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.

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.
