Impact on humans. The domestication of animals began with the wolf (Canis lupus) at least 15,000 years before present (YBP), which then led to a rapid shift in the evolution, ecology, and demography of both humans and numerous species of animals and plants.
Later finds gave a more comprehensive impression of how the animal must have looked, and the species was renamed Eohippus, meaning dawn horse. The domestication of horses is thought to have happened in Babylon, Assyria, Egypt and parts of Eurasia between 6,500 and 7,000 years ago.
