The is a brief description of the tree for those who are visually impaired. Hyracotherium is shown giving rise to three lineages.

Two lineages quickly go extinct. The third branches many times. There are many branches alive during most times until two million years ago when only the various species of Equus remain. The tree itself is unreadable to those who are visually impaired so skip the tree graphic.

This little animal " at the shoulder looked nothing at all like a horse.

It had a "doggish" look with an arched back, short neck, short snout, short legs, and long tail. It browsed on fruit and fairly soft foliage, and probably scampered from thicket to thicket like a modern muntjac deer, only stupider, slower, and not as agile. This famous little equid was once known by the lovely name "Eohippus", meaning "dawn horse".

Some Hyracotherium traits to notice: Legs were flexible and rotatable with all major bones present and unfused. Hyracotherium walked on pads; its feet were like a dog's padded feet, except with small "hoofies" on each toe instead of claws.

Small brain with especially small frontal lobes. Low-crowned teeth with 3 incisors, 1 canine, 4 distinct premolars and 3 "grinding" molars in each side of each jaw this is the "primitive mammalian formula" of teeth.

The cusps of the molars were slightly connected in low crests.

Horse Evolution

Typical teeth of an omnivorous browser. At this point in the early Eocene, equids were not yet very different from the other perissodactyl groups; the Hyracotherium genus includes some species closely related to or even ancestral to rhinos and tapirs, as well as species that are distinctly equine.

In fact, throughout most of the Eocene a good long 20 million yearsonly minor evolutionary changes took place in Hyracotherium and its near descendants. The body and feet stayed mostly the same, with slight changes in the toes.

The major change was in the teeth; as Eocene equids started to eat more plant browse and less fruit, they developed more grinding teeth to deal with the slightly tougher food. Orohippus In the early-middle Eocene approx 50 Mythere was a smooth, gradual transition from Hyracotherium to a close relative, Orohippus MacFadden, “What is the order of a cat?” sounds rather strange.

On the face of it it does not make sense. However, the question revolves around the word “order” which is one level in the scientific classification of the domestic cat.

The Holocene extinction, otherwise referred to as the Sixth extinction or Anthropocene extinction, is the ongoing extinction event of species during the present Holocene epoch, mainly as a result of human activity.

The large number of extinctions spans numerous families of plants and animals, including mammals, birds, amphibians, reptiles and arthropods. + free ebooks online. Did you know that you can help us produce ebooks by proof-reading just one page a day?

Ethics of Zoos - There are many places where people can go to see live animals such as aquariums, zoos, and safari parks. A pleasant way to define a Zoo is to call it “an establishment that maintains a collection of wild animals”.
