EVOLUTION AND NATURAL SELECTIONEvolution of the Horse (Hyrac oppositeium ) SpecieNameSchoolProfessorSubjectEvolution of the Horse (Hyracotherium ) SpecieThe individual cash of a horse known as Hyracotherium was believed to be the origin of the moderne horses today known as genus Equus . The dodo lineage of primitive horses provided an evidence of directional taking over in evolution . Evolution took placed as seen in the changes and development in the teeth , leg length and toe structureThe Hyracotherium was first open in Europe . It was hence named Eohippus . It had lived 55 cardinal years ago . It was found during the Early Eocene era . During that time this kind of animal was third estate and found in other parts of the world . The fossil of this horse was collected and studied by scientist and found similarities with other early horses . It was replaced by Orohippus specie known as small-scale horse and much bigger than the hyracotherium . This appeared 2 million years after it . Hyracotherium was described to be the coat of a dog . It had a primitive face , with essence sockets in the middle and a short diastema or the plaza between the front teeth and the cheek teeth . It has low crowned teeth but with the characteristic of horse wish ridges in the molars . Horses was believed to come from this small type of dog standardized animal which according to the theory of evolution and natural alternative undergone extinction while its later generation evolved and improved to the modern horses we have seen todayThe emergence of the Parahippus specie became somewhat the evolutionary middleman between the oldest hyracotherium horses to the modern horses .

From a small embody , shorter face , three toes and small teeth these species evolved into taller and larger bodies with longitudinal face and one toed feature . Millions of years had passed and active 15 generations occurred before the modern horses came into the picture . They improved in their characteristics as more and more horses were domesticated and used as a means of transportation . From living in woodlands it go to living in the highlands . Its legs were developed to help them from predators making them withstand more in the environment therefore preserving the specieReference Evolution and indispensable Selection .
