were horses in the old world
The horse (Equus caballus) has made many dramatic and significant journeys. During the Pleistocene (Ice Age), more than 20,000 years ago, wild horses that had evolved in America migrated to the Old World, Eurasia and Africa. More than 6,000 year ago in the Volga basin of eastern Europe horses were domesticated and in the subsequent millennia spread to other parts of Asia, Europe, and Africa.
