Fast-running animals are well adapted to the steppe because the environment is characterized by wide, open grasslands that lack natural shelter or hiding places. This landscape necessitates the evolution of large herbivores that possess sharp senses and the ability to run quickly to escape predators or migrate to new pastures.12

The lack of cover in the low vegetation means that animals cannot easily hide, making speed a critical survival trait. Consequently, many steppe-dwelling mammals have developed cursorial (running) adaptations, such as a digitigrade or unguligrade stance, which allow for efficient movement across the plains. This evolutionary pressure has resulted in a fauna that includes various fast-moving species, such as the horse, gazelle, and saiga antelope, all of which are highly adept at navigating the open terrain.123
