The history of the horse

The prehistoric fossil records show that equidae (what is now known as the horse) suffered the majority of its evolutionary history in the last years of $ 60 million.

This first horse was given the name Hyracotherium in Europe and America Eohippus.

Eohippus was a browser, feeding on soft sheets and despite its short legs was able to move between the Marsh lands and lush forests.

Because of its diet soft it did not require the use of molar wholesale that were not evident at this stage of evolution.

Eohippus had small succulent food snip sharp incisors ale, a small skull and the forward pointing eyes with only 6 teeth small plays triangular arcade along.

In the course of the succeeding dramatically changed climate to 50 million years and the beginning of the ice age caused a change in the landscape and the available vegetation. During this period the adapted eohippus descendants change and has evolved to keep pace.

Now more open and more dry landscape brought many changes. To survive this time animals had to flee more large terrestrial predators. The more evolutionary descendants success evolved for these purposes.

Their members have grown longer (relative to the size of the body). Their five fingers reduced to a single digit faster recessed in a hoof protection. Modes of feeding has changed because of an increased threat of predator and the influences of the environment. They have become nomadic, always in motion. Living in herds for greater protection. Grazing of grassland aircraft for long periods of time

The Anatomy of the head and teeth also evolved

-They now seize grasses in short circuit courts which are now stable food, with their lips first before using an action pincer with their incisors.

-Head had elongated to accommodate larger molars bowling to crush course grasses more time

-The larger size of skull also saw a change in the situation of the orbits to a more laterally situation. This allowed a field of view wilder allow a continuous grazing while watching for predators.

These changes increased gradually but for the purposes of survival and we gave the horse we know today, Equus.
