That's almost right, but you have the Botai horse and Przewalski's horse confused. The Botai were a human culture living in what is now Kazakhstan, approximately 3700-3100 BCE. They kept domesticated horses, and are the earliest culture known to have done so, so "Botai horse" would be a name for whatever kind of horses they had. Przewalski's horse is a population of horses that exists today. It was considered the last wild horse (meaning: neither domesticated nor descended from domesticated horses), but the article says it is merely a feral population descended from Botai horses.
