A Brief History of Horses. By 55 million years ago, the first members of the horse family, the dog-sized Hyracotherium, were scampering through the forests that covered North America. For more than half their history, most horses remained small, forest browsers.
The large strong heads and erect manes depicted in these paintings bear a striking resemblance to this modern breed. The first domestication of the horses was probably in the steppes of central Asia between 3000 and 4000 B.C. These first animals were kept for meat and milk.
