Evolutionary approach suggests that language results from some innate capacity shaped by natural selection, which implies that we might be able to find precursors of human language in the behavior of other animals
Step-by-step explanation:
Evolutionary linguistics is a sub-field of psycho linguistics that deals with the cultural factors in the origin of language and also "development of linguistic universals". The main challenge is the "spoken language leaves practically no traces".
This approach also deals with a scientific discipline that approaches human behavior which joints with the effects of evolution. The evolutionary approach is the reason that the "human race continues to survive" and continues to perform in best way through natural selection.
