2. Sample

The diagrams illustrate the evolution of equine species through the span of 40 million years, represented by the modern horse and its three ancestral species, with a clear focus on the morphological changes of the foot.

Overall, while all four species share the common trait of being quadrupedal, equine species have increased in size, evolved to have more hair (on the tail and mane) and gone from having toes to a single hoof on each foot.

The Eohippus, which lived 40 million years ago, had four short legs that supported a relatively small torso and its tail was barely observable. Its two descendants, Mesohippus and Mecrychippus, which are respectively estimated to exist 30 million and 15 million years ago, started to have elongated tails and rudimentary form of the mane; and whereas their bodies increased slightly in height, the overall stature was largely unchanged. The modern horse possesses the most pronounced tail and mane; it is also the largest animal whose height and length of body are about three halves of its oldest shown ancestor.

The foot of Eohippus stands out the most for having four separated toes with thin phalanges. In Mesohippus and Merychippus, the number of digits is reduced to three and the middle phalanx is enlarged so the whole foot’s morphology starts to resemble a hoof. The modern horse’s foot has the fewest bony structures and the hoof has replaced toes.
