Editing Horse (section)

===Ancestry===
Horses were probably born around 3000 BC. First domesticated in Central Asia. There are contradicting theories as to when and where exactly the horse was made usable by humans. Final examinations. which are based on the evaluation of the mitochondrial DNA of today's domestic horses and of fossils of extinct species suggest that the domestication of the horse did not take place in one place, but independently of one another in several places. An essential indicator for this is the breadth of the genetic variations, which is the same in both test groups. With only one place of domestication, a lower genetic range of variation would have been expected in domestic horses. In addition, during these tests, it was found that some of the fossil finds were more closely related to today's species,

Investigations of mitochondrial DNA in 2002 showed that there were at least 77 strain types in mares, suggesting that different wild horse populations in different regions of the world have been domesticated independently of one another; considerably more than with other types of pets.

The wild Przewalski horse apparently does not belong to the ancestors of the domestic horse, as the ancestral lines separated already 120,000 to 240,000 years ago.
