    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 InkArt.net

              The Spanish didn't just bring one or two stallions. They had over a hundred knights to support, and they knew they were colonists needing to breed more, so they also brought brood mares. A ship would carry 6 or 8, or even more horses, and they had lots of ships. Plus, this didn't happen only once.

              Read the history of Cortez' venture into Florida and across the south of North America. They reported losing dozens of horses, escaping and stolen.

              Columbus set up a home base for exploration on the island of Hispaniola, and in the next wave, they were definitely breeding horses there. Since it was already obvious that there were none here, they knew that horses would be a military advantage.

                      North American Indians like to brag that horses are their heritage and a huge part of their culture. WHAT! not so.

                          The Appaloosa horse actually came over with the Native Americans from Asia and was here long long before the Spanish and European people brought their horses to the Americas. This video needs to be updated with this information.

                              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
