The gradual evolution for the family Equidae (horse family) has been well documented within the fossil record.

Explanation:

Homologies between various horse species and horse-like ancestors have been observed within the fossil record. These homologies provide evidence of evolution. If you need more information, the website for The American Museum of Natural History has an interesting article on horse evolution. Wikipedia also has some useful information.
