Horses originally evolved in the Americas. They then migrated to Europe and became extinct in the Americas. However, when they were brought over by settlers, some then escaped and adapted quite well to life as wild horses again, which is where mustangs come from. I think this is especially awesome, because although I knew horses were introduced to the US from European settlers, I never knew before that they ORIGINALLY EVOLVED HERE! They fit in so well in the West and with all those cowboy tales because they were supposed to be here. (Although, admittedly, they went extinct, so obviously a problem happened somewhere along the line).Labels: horses, Random
