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.

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.

A New York Times Bestseller and New York Times Book Review Editors' Choice A Best Book of 2015, The Wall Street Journal "Love is the driver for Wendy Williams's new book, The Horse . . . [an] affectionate, thoroughgoing, good-hearted book." —Jaimy Gordon, The New York Times Book Review "Charming and deeply interesting . . . Ms. Williams does a marvelous job." —Pat Shipman, The Wall Street Journal The book horse-lovers have been waiting for Horses have a story to tell, one of resilience, sociability, and intelligence, and of partnership with human beings. In The Horse, the journalist and equestrienne Wendy Williams brings that story brilliantly to life. Williams chronicles the 56-million-year journey of horses as she visits with experts around the world, exploring what our biological affinities and differences can tell us about the bond between horses and humans, and what our longtime companion might think and feel. Indeed, recent scientific breakthroughs regarding the social and cognitive capacities of the horse and its ability to adapt to changing ecosystems indicate that this animal is a major evolutionary triumph. Williams charts the course that leads to our modern Equus-from the protohorse to the Dutch Warmbloods, Thoroughbreds, and cow ponies of the twenty-first century. She observes magnificent ancient cave art in France and Spain that signals a deep respect and admiration for horses well before they were domesticated; visits the mountains of Wyoming with experts in equine behavior to understand the dynamics of free-roaming mustangs; witnesses the fluid gracefulness of the famous Lipizzans of Vienna; contemplates what life is like for the sure-footed, mustachioed Garrano horses who thrive on the rugged terrain of Galicia; meets a family devoted to rehabilitating abandoned mustangs on their New Hampshire farm; celebrates the Takhi horses of Mongolia; and more. She blends profound scientific insights with remarkable stories to create a unique biography of the horse as a sentient being with a fascinating past and a finely nuanced mind. The Horse is a revealing account of the animal who has been at our side through the ages, befriending us and traveling with us over the mountains and across the plains. Enriched by Williams's own experience with horses, The Horse is a masterful work of narrative nonfiction that pays tribute to this treasure of the natural world.
