Evolution of Horse
Evolution of Horse DEFINITION Evolution of Horses The phylogenetic sequence in the evolution of horse is dependent on environmental conditions. Hyracotherium or Eohippus lived in marshy forests with abundant soft vegetation and protection. Due to climate changes, there was declination in the number of forests. As a result, Hyracotherium had to shift to lands and hard grass. Hence, the molar teeth of these organisms became longer, stronger and sawlike to chew grass. Neck and snout became longer to keep an eye on the enemies. Legs became modified to assist fast running on open ground. DEFINITION Eohippus The modern horse started evolving about 5 years ago in the eocene epoch in North America. The first species was a fox sized species named as Eohippus. Fossils helped in deriving these information. Richard Owen, a palaeontologist found the first fossils of Eohippus in the year 1841. He renamed the species as Hyracotherium. They spread throughout Asia and Europe. Th...
