ETYM Latin locus place + motio motion: cf. French locomotion. Related to Local, and Motion.
The ability to move independently from one place to another, occurring in most animals but not in plants. The development of locomotion as a feature of animal life is closely linked to another vital animal feature, that of nutrition. Animals cannot make their food, as can plants, but must find it first; often the food must be captured and killed, which may require great speed. Locomotion is also important in finding a mate, in avoiding predators, and in migrating to favorable areas.
