A large body size is advantageous for horses, so horses became larger and larger throughout their evolutionary history. this is an example of Directional selection

The domesticated horse  is a hoofed, one-toed mammal. It is one of the two existing subspecies of Equus ferus and a member of the taxonomic family Equidae. Eohippus, a small animal with several toes, was the ancestor of the horse, which developed over the course of the last 45 to 55 million years to become the huge animal it is today. Horse domestication is said to have started approximately 4000 BC and expanded significantly by 3000 BC. The caballus subspecies of horses are domesticated, yet certain populations of domesticated horses roam freely as wild horses. Since this term is only used to refer to horses that have never been tamed, these feral populations are not actually wild horses.
