Locomotion on land raises different problems than that in water, with reduced friction being replaced by the increased effects of gravity. As viewed from evolutionary taxonomy, there are three basic forms of animal locomotion in the terrestrial environment: legged – moving by using appendages
Another example is the blue wildebeest, the calves of which can stand within an average of six minutes from birth and walk within thirty minutes; [5] [6] they can outrun a hyena within a day.
