One approach to language suggests that it 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. This is called the approach.

Evolution Approach.

Explanation:

The evolution approach to language is the theory that is based on the assumptions of Darwin's theory of evolution. This theory suggests that humans possess the innate capacity to understand language that was shaped by natural selection. Darwin's theory of natural selection suggested that the population is prone to become adapted to its natural environment over time.

According to this theory of natural selection, it is assumed that humans had inner ability to adapt the language.

So, the correct answer is evolution theory.
