The horse (Equus ferus caballus) [2] [3] is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus . The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus , into the large, single-toed animal of today.

[2] [3] [4] Equoids may in part be defined by dental synapomorphies from its molars. [5] Equoids were originally brachyodont (low-crowned) in dentition, but the morphologies of their molars had changed to adapt to different diets. Living equids are hypsodont, the result of evolutionary adaptations towards grazing diets. [6]
