Default Ancient DNA upends the horse family tree

Ancient DNA upends the horse family tree


Horses radically changed human history, revolutionizing how people traveled, farmed, and even made war. Yet every time we think we’ve answered the question of where these animals came from, another study brings us back to square one. Such is the case with an extensive new study of ancient horse DNA, which largely disproves the current theory: that modern horses arose more than 5000 years ago in Kazakhstan. Instead, the new work suggests that modern-day domestic horses come from an as-yet-undiscovered stock. The research also shows that the world’s only remaining wild horses, called Przewalski’s horses, are not truly wild.
