What theoretical perspective argues that the increase in obesity in humans is a result of the fact that early humans lived in environments in which there was fierce competition for limited, unreliable food resources and that they developed a tendency to consume food when it was present?

A) cognitive
B) evolutionary
C) body-set point
D) settling-point

The evolutionary perspective argues that humans developed a tendency to consume food when it was present due to the fierce competition for limited and unreliable food resources in their early environments, which has led to an increase in obesity in modern times. The cognitive perspective focuses on how our thoughts, beliefs, and attitudes influence our behavior, while the body-set point and settling-point perspectives focus on the physiological mechanisms that regulate body weight.
