Resumen:
In this chapter we analyze and discuss the phylogenetic hypothesis about horses based on morphological and molecular data. Recent analyses proposed that all contemporary equids belong to a single genus, Equus and their ancestor lived in North America approximately 4.0?4.5 Ma. The ancestors of South American Equus arrived and appeared approximately 1 Ma. The lineage corresponding to Hippidion appeared approximately 2.5 Ma and includes two genetically similar generalists (Hippidion principale, Hippidion saldiasi) and one genetically distinct high-altitude specialist (Hippidion devillei).
