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.

In 1831, the twenty-two-year old Charles Darwin embarked on the Royal Navy ship H.M.S. Beagle as it set off on what was to be a five-year-long surveying expedition around South America and across the Pacific. Darwin was employed officially as a naturalist and geologist to assist in the survey, but unofficially as a companion to the captain, Robert Fitz Roy. Darwin was a keen and intelligent observer, and made a number of discoveries on the journey, including the observations at the Galapagos Archipelago which eventually led him to his theory of evolution (later outlined in The Origin of Species). His voyage across the Pacific also led him to propose a now largely-accepted theory of the formation of coral atolls. Darwin submitted his journal and notes as part of the official report of the expedition, but in 1839 he published a more readable account of his experiences in this book, initially titled Journal of Researches Into the Natural History and Geology of the Countries Visited During the Voyage of H.M.S. Beagle Round the World Under the Command of Capt. Fitz Roy, R.N.. The book quickly became very popular, and the publisher had to release a second edition later the same year. The revised and much simpler title The Voyage of the Beagle was only given to the work in 1905. Adding to the interest of Darwin’s detailed and thorough observations of nature and geology are his deeply critical remarks on the institution of slavery, which he witnessed during his time in Brazil. This of course was three decades before the Civil War in the United States which was fought over that issue. This book is part of the Standard Ebooks project, which produces free public domain ebooks.

First published in 1839, “The Voyage of the Beagle” is the book written by Charles Darwin that chronicles his experience of the famous survey expedition of the ship HMS Beagle. Part travel memoir, part scientific field journal, it covers such topics as biology, anthropology, and geology, demonstrating Darwin's changing views and ideas while he was developing his theory of evolution. A book highly recommended for those with an interest in evolution and is not to be missed by collectors of important historical literature. Contents include: “St. Jago—Cape De Verd Islands”, “Rio De Janeiro”, “Maldonado”, “Rio Negro To Bahia Blanca”, “Bahia Blanca”, “Bahia Blanca To Buenos Ayres”, “Banda Oriental And Patagonia”, etc. Charles Robert Darwin (1809–1882) was an English geologist, naturalist, and biologist most famous for his contributions to the science of evolution and his book “On the Origin of Species” (1859). This classic work is being republished now in a new edition complete with a specially-commissioned new biography of the author.

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.

Every fossil tells a story. Best-selling paleontology author Donald R. Prothero describes twenty-five famous, beautifully preserved fossils in a gripping scientific history of life on Earth. Recounting the adventures behind the discovery of these objects and fully interpreting their significance within the larger fossil record, Prothero creates a riveting history of life on our planet. The twenty-five fossils portrayed in this book catch animals in their evolutionary splendor as they transition from one kind of organism to another. We witness extinct plants and animals of microscopic and immense size and thrilling diversity. We learn about fantastic land and sea creatures that have no match in nature today. Along the way, we encounter such fascinating fossils as the earliest trilobite, Olenellus; the giant shark Carcharocles; the "fishibian" Tiktaalik; the "Frogamander" and the "Turtle on the Half-Shell"; enormous marine reptiles and the biggest dinosaurs known; the first bird, Archaeopteryx; the walking whale Ambulocetus; the gigantic hornless rhinoceros Paraceratherium, the largest land mammal that ever lived; and the Australopithecus nicknamed "Lucy," the oldest human skeleton. We meet the scientists and adventurers who pioneered paleontology and learn about the larger intellectual and social contexts in which their discoveries were made. Finally, we find out where to see these splendid fossils in the world's great museums. Ideal for all who love prehistoric landscapes and delight in the history of science, this book makes a treasured addition to any bookshelf, stoking curiosity in the evolution of life on Earth.
