Sixty million years ago, in the Eocene epoch, the doglike eohippus flourished in swampy forests where it browsed on leaves. The Eohippus had little or no lateral vision and had a coat similar to a deer in texture and in color right down to fawn like spots to help to camouflage them. It had molars with small grinding surfaces to chew the succulent leaves of its forest habitat. Eohippus was about the size of a fox, had four toes on its forefeet and three on its hind feet which were padded like those of a dog and allowed easy movement over wet ground. These toes and pads are now the ergots and splint bones found on the legs of the modern horse. Eohippus was a browsing animal that lived on soft leaves growing on low shrubs.
By the Oligocene period, about 38 million years ago, Eohippus had evolved into Mesohippus and had achieved the size of a German Shepherd. This evolution was taller and heavier, with teeth that allowed them to eat a wider variety of plants. They were still browsers living in forests and swamps. Their front feet were reduced to three toes, still padded, but the middle toe carried most of the weight. Mesohippus lived in this more open country where it ran and trotted. It was adapted for running in open country. .
With the spread of Miocene grasslands 25 million years ago, only the descendants whose teeth had adapted to grinding survived. The drying climate produced harder ground, and the middle digit of Merychippus, expanded to bear the strain of its increased weight. As it adapted to changing conditions, the neck and head became longer, the incisors moved forward in the skull and the form and position of the eyes altered to allow the horse to view the horizon while grazing. The Merychippus began to develop defenses and a heightened sense of smell. The teeth changed to those more like today's horses. These 3 toed grazers were believed to be quick, speedy and surefooted to escape from predators.

Is Darwin's account of evolution "just a theory-? Darwin's account of evolution is not "just a theory-, it is scientific philosophy and according to Popper, it is this: "Evolution cannot be proved or disproved; it resides in a magical other world beyond scientific facts and commonplace reality. Evolution cannot be disproved, for it cannot be falsified. ... Is the theory of evolution a scientific theory or an established fact? It is important to differentiate between: q The broad concept of evolution: The vast majority of scientists have long accepted that the Theory of...
Evolution Evolution is a process of gradual change. ... Fossils provide the most direct evidence of evolution. ... Horses are among the best-documented examples of evolutionary development. Fossils show many stages in the evolution of the horse. ... In Darwin's time, many scientists, religious leaders, and other groups attacked the theory of evolution. ...
Geology, the largest "supporter" of evolution, actually gives the theory the biggest problem. ... Huse states in The Collapse of Evolution. ... Vertical variation (macro-evolution) is when one organism turns into an ent! ... Dogs never turn into horses. ... When a person breeds a horse and a donkey the result in a mule. ...
Evolution Evolution, a process of change through time, is what links together the enormous diversity of the living world. ... Today there are many theories and possibilities related to evolution which contribute to our understanding of the process. ... Jean Baptiste de Lamarck had his own proposal of evolution. ...

The history of evolution tells the beginning of a story about natural selection. ... Some say, as stated in Asimov's New Guide of Science ARTICLE by Isaac Asimov, "There are many kinds of roses, finches, dogs, and horses "but all the roses, finches, dogs, and horses are just that; they never change into daisies, parrots, cats, or cows."" ...

The Theory of Evolution The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. ... There is NO evidence on the molecular level for evolution. ... This means that some of the classic cases of Darwinian change in the fossil record, such as the evolution of the horse in North America, have had to be discarded or modified as a result of more detailed information-what appeared to be a nice simple progression when relatively few data ...
