Human skeleton, showing plantigrade habit In mammals, plantigrade locomotion means walking with the podials and metatarsals flat on the ground. Plantigrade locomotion is considered less specialized or less highly evolved than digitigrade and unguligrade locomotion.
Humans are an example of a plantigrade species; and in humans the podials and metatarsals constitute the sole of the foot. Other plantigrade species include raccoons, opossums, bears, and rabbits.
