Answer: Evolutionary
Explanation: An evolutionary perspective in psychology is an approach that explains that there are traits and habits that are useful for natural selection. According to Professor Parker, heterosexual adults are destined for monogamy and thus these traits are useful for reproduction and nurturing of children as conditions for survival and evolution. This theory therefore speaks of traits that are useful for adaptation and thus create a mechanism for survival. So useful mental and psychological traits and habits such as monogamy, heterosexuality are a prerequisite for survival and evolution, but also the result of evolution, because the traits that have survived are a consequence of natural selection.
