The interesting part is that they evolved in America, crossed over to Asia (and from there to Europe and Africa) through the Bering land bridge, and then went extinct in America together with the American megafauna (possibly because of overexploitation by recently arrived humans, possibly due to climate change, possibly a combination of both), only to be reintroduced later on.
