Behavioral Biology (Ethology)

Behavioral Biology, also known as Ethology, is the scientific discipline dedicated to understanding animal behavior from an evolutionary perspective. It investigates both the proximate causes of behavior—such as the genetic, developmental, and physiological mechanisms that trigger an action—and the ultimate causes, which concern the behavior's adaptive value and its evolutionary history. By studying topics like communication, mating strategies, foraging, and social interactions, often in an animal's natural environment, this field seeks to explain how behaviors contribute to an organism's survival and reproductive success.
