Final answer:
Human behavior is influenced by both innate tendencies and environmental factors, such as cultural pressures. There is a tendency for humans to identify with an in-group and seek approval, which is believed to be innate but culturally influenced.
Step-by-step explanation:
Most anthropologists have come to agree that human behavior is influenced by a combination of innate or genetically determined tendencies and environmental factors, especially cultural pressures. Humans have flexible biological and social features that allow them to adapt to different environmental and historical conditions, resulting in a diversity of cultures. The tendency for people to identify with an in-group, seek approval, and avoid disapproval is believed to be innate, but the criteria of approval and disapproval are largely culturally determined.
