How Horses Took Over North America (Twice)

  • Published: 15 August 2018
  • The PBSDS Annual Audience Survey:

    The ancestors of modern horses became so successful that they spread all over the world, to Europe, Asia, South America, and Africa. But in their native range of North America, they’ll vanish for 10,000 years. Until another strange mammal brings them back.

    The illustration of Equus Simplicidens--also known as the Hagerman Horse--is by Roger Hall. You can check out more of Roger's work at

    I have a book that shows and explains the entire evolution of a horse. To watch a video explaining how they took over north america is very nice. Thank you
    Without horses, we would have lost a war. Can't remember which war, but without using horses it would have been lost and some things would be very different today.

          Why are ancient horses like Equus simplicidens always depicted with zebra stripes ( mosttime partly)? Is stripes an ancient feature present but domant in all members of the genus Equus or is it a feature that appeared on zebra's only that lived in a tse-tse infested area? One theory states that zebra striping is closely linked to the presence of tse-tse flies against the diseases they carry in frica origanted herbivore are immune, but the later invading equines were not.

                The Eohippus is half a meter tall and its descendants grow 30 times their size? If you do the math that would make horses 15 meters tall. Interesting Image

                                      nature is very smart if you dont want to go extinct attach yourself to humans. Just like horses, dogs, cats, rates and flies.

                                   could there be global warming millions of years ago? There weren't any humans around to cause it. Maybe early mammals were driving cars and we haven't discovered them yet.
