Great chart but here is a question. We are taught in school and biology as well that horses are not native to north america. The chart would show them being here 3 to 5 million years ago. We are taught that horses come to america with Columbas and migrated from south america and up into north america.Yes:

Basically horses did most of their evolving in North America.
There is a more detailed look at the evolution of the horses at Horse Evolution.
