One night, you go to a lecture by a psychologist who emphasizes our early ancestors. for example, when describing marital infidelity, he suggests that our ancestors were not monogamous because not being monogamous was adaptive behavior and increased the chances for survival. it is likely that the psychologist endorses the approach.

It is likely that the psychologist endorses the "evolutionary" approach.

The evolutionary approach endeavors to clarify mind and behavior as far as organic structures and procedures that have advanced more than hundreds to thousands of ages. This approach expect that species have developed methods for reacting (subjectively, inwardly, and typically) to ecological occasions on the grounds that these reactions prompted more noteworthy survival and conceptive accomplishment in genealogical population.
