Darwin's evaluation theory what does it say about language and communication

Communication: He proposed that much like other traits found in animals, emotions also evolved and were adapted over time.

Language: language "owes its origins to the imitation and modification, aided by signs and gestures, of various natural sounds, the voices of other animals, and man's own instinctive cries".

communication and language came from nature over many years.
