It’s the latest discovery in a longstanding quest for the animal’s origin.
We know the ancient Botai people of modern-day Kazakhstan had horses 5,000 years ago.
But a 2018 study uncovered that those equines’ genetics do not match up with the horses of today.
An October 21 paper in Nature provides new evidence that today’s modern horses were first domesticated in Western Eurasian steppe more than 4,200 years ago.

The other is the feral Przewalski’s horse, Equus ferus przewalskii, which is actually the descendant of the Botai peoples’ domesticated ponies.

The Nature study suggests that the descendants of today’s domestic horses came from a region in modern-day Russia called the Volga-Don.
