In this chapter, we analyze the patterns of vicariance and dispersal in fossil horses and the relationship with the environmental changes. We found that predominance of the dispersal events over vicariant ones is consistent with the migratory habits of horses. Ancestral distribution for the Equini tribe was ranged widely across North America. This distribution could have been succeeded during the middle to late Miocene, a time of tectonic and climatic change, and an increasing number of grasslands.
