Principles of Donkey Movement

Observed through historical epochs and evolutionary periods, the movement of mammals basically developed into two groups. One group consists of ungulates (Perissodactyla), and the other group consists of ungulates (Artiodactyla). Among ungulates, wild and tame horses, wild and tame donkeys, and semi-donkeys were distinguished by the specific movement of their legs forward. We call this whole group Equiden.
