Final answer:
Human communication involves the use of language, while non-human animals communicate through other means such as sounds, postures, movements, and scents.
Step-by-step explanation:
Human communication involves the use of language, which is the use of symbols, such as words, to convey meaning. Humans communicate through spoken and written language, as well as through facial expressions and gestures. Non-human animals, on the other hand, communicate through other means such as sounds, postures, movements, and scents. While some non-human animals, such as primates, can learn basic vocabulary and use simple word combinations, their communication abilities are limited compared to human language.
