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.

Although this question is incomplete, we can still provide some information that can help guide your answer.
Buffalos (or bisons) were once a common sight in the American plains. While in the early 1800s about 60 million of these could be found across the country, the number was reduced to about 27 by the early 1900s. Government efforts have brought back this species from the brink of extinction.
While often associated with the American West, these animals lived in other regions of the country, including Texas. However, the buffalo population in Texas was not always regular. It varied based on several factors, including many geographic ones. For example, when rain was scarce, vegetation was hard to find. Water was also found in limited supply. This led the buffalo to migrate to other areas. Similarly, areas with fertile soil were used for agriculture, which made the land unavailable to the herds. These are examples of geographic factors that had a significant impact on buffalo in Texas.
