How come horses were so common all over the world in the past

Question

I recently watched a documentary about a brief history of each continent when I noticed horses were really common everywhere for an example Genghis khan in Asia, Saladin in Africa, natives in North and South America and all over Europe too. I know they’ve been brought with settlers to Australia because it was mentioned in the documentary but what about the other continents ?

Answer 1

Horses originally came from North America. At least their ancestors did. They crossed into Asia and evolved into the modern horse. Their ancestors back in the Americas went extinct and were cut off from Asia and Europe. Eventually the Europeans brought them to America and released them into the wild. The Americas just have a really good climate for horses.
