PRLog - Dec. 24, 2012 - DELHI, India -- The evolution of the horse pertains to the phylogenetic ancestry of the modern horse from the small, dog-sized, forest-dwelling Eohippus over geologic time scales. Paleozoologists have been able to piece together a more complete picture of the modern horse's evolutionary lineage than that of any other animal.

The horse belongs to an order known as Perissodactyla, or "odd-toed ungulates", which all share hooved feet and an odd number of toes on each foot, as well as mobile upper lips and a similar tooth structure. This means that horses share a common ancestry with tapirs and rhinoceroses.
Horse evolution is cited as the best example in support of Darwin’s mechanism of evolution essentially consisting of continuous, gradual evolution by accumulation of random variations over immense periods of time. In this context, Equidae fossils discovered are said to form a horse series that is consistent with Darwin’s mechanism of evolution.
North America is presumed to be horse’s natural habitat. About 55 million years ago there is supposed to be a dry land in the place where present strait of Bering is. However there is no geological or geographical evidence to support this contention. There are only presumptions. The ancestors of American horses migrated to Asia, later Europe and distant Africa along this “bridge”. Even archeologists cannot find their tracks. Even the timeline of horse migration is different in different references varying from 25 million years to 5 million years. For unknown reasons 30 million years ago horses disappeared from America. No reason for extinction of Equidae family from North America has ever been provided. One of the suppositions is that the sting of some fly was poisonous to horses. Moreover if horses became extinct from North America 25 million years back, then where were the horses left to migrate to Asia along Bering Land Bridge.Only in the 16th century horses were brought to America by conquistadors.
The Bering Strait is approximately 82 kilometres (51 mi; 44 nmi) wide at its narrowest point, with depth varying between 98 feet (30 m) and 160 feet (49 m).It connects the Chukchi Sea (part of the Arctic Ocean) to the north with the Bering Sea (part of the Pacific Ocean) to the south. This is supposed to have transformed into Bering Land Bridge, several times in the geological and geographical history of Earth to permit migration of flora and fauna across North American and European continents and then to Asia and Africa. Bering Land Bridge is said to be 1000 Km wide from NORTH to SOUTH. However the only reason cited in support of such a contention is compulsion of Biogeography. To quote:
“Some, like the ancient saber-toothed cats, have a recurring geographical range: Europe, Africa, Asia, and North America. The only way they could reach the New World was by the Bering land bridge. Had this bridge not existed at that time, the fauna of the world would be very different.”
There is no independent geological or geographical evidence to support existence of Bering Land Bridge. Hence the only difficult with this presumption is that presumes the fact it has to prove.
Despite an excellent fossil record of the Equidae, there are still many gaps in our evolutionary knowledge. Only the modern horse, zebras, wild asses and donkey survive today, but many other lineages have become extinct over the last 50,000 years. Detailed fossil information on the rate and distribution of new equid species has also revealed that the progression between species was not as smooth and consistent as was once believed. Although some transitions, such as that of Dinohippus to Equus, indeed appear to be gradual progressions, a number of others, such as that of Epihippus to Mesohippus, were relatively abrupt in geologic time, taking place over only a few million years. The change in equids' traits was also not always a "straight line" from Eohippus to Equus: some traits reversed themselves at various points in the evolution of new equid species, such as size and the presence of facial fossae, and only in retrospect can certain evolutionary trends be recognized.
Therefore all the accumulated evidences points only to morphological trends and patterns in Equidae family on empirical basis and are no evidence to conclude any straight line evolution from from the small, dog-sized, forest-dwelling Eohippus over geologic time scales to modern horse in accordance with Darwin’s Mechanism of Evolution. Hence, the observed evolutionary morphological trends and patterns lend no credibility to Darwin’s mechanism of Evolution. There is no evidence to show that ancestors of modern horse actually migrated to Europe through Bering Strait. In fact extinction of horses in North America 30 million years ago precludes such migration. In fact, all the evidence points to correlations, associations and correspondences;
Cumulative evidence suggests some other mechanism of evolution other than Darwinism. Observed morphological trends and patterns are nothing more than correlations, associations and correspondences that are commonly seen in our study of nature. Empirical data does not fit into Darwin’s mechanism of evolution.
Author: Dr Mahesh C. Jain is a practicing medical doctor and has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. This is the only book which deals with origin of nature and universe from null. Thirtieth chapter of the book deals with the subject matter of ‘Evolution of Life’.
