Final answer:
The idea that human behaviors are related to our biological evolution is associated with evolutionary psychology, which links behaviors to genetic factors and views them as adaptations shaped by natural selection.
Step-by-step explanation:
The idea that human behaviors have to do with our biological evolution as a species is most closely associated with evolutionary psychology. This field of psychology looks at how certain behavioral tendencies may have developed because they were advantageous in terms of survival or reproductive success. While all behaviors have a complex range of influences, evolutionary psychology specifically searches for behaviors that can be linked to genetic factors, theorizing that these behaviors are adaptations shaped by natural selection throughout our evolutionary history.
