All the wild horses are extinct: studye

Miami : All the world’s wild horses have gone extinct, according to a study that unexpectedly rewrites the horse family tree based on a new DNA analysis of their ancestry.

What most people thought were the last remaining wild horses on Earth — known as Przewalski’s horses — were actually domesticated horses that escaped their owners, said the report in the journal Science.

“This was a big surprise,” said co-author Sandra Olsen, curator-in-charge of the archaeology division of the Biodiversity Institute and Natural History Museum at the University of Kansas.

“This means there are no living wild horses on Earth — that’s the sad part,” said Olsen.

The study is based on archaeological work at two sites in northern Kazakhstan, called Botai and Krasnyi Yar, where scientists have found the earliest proof of horse domestication, going back more than 5,000 years.
