Animal behavior, or ethology as scientists call it, encompasses every action an animal takes in response to its internal state and external environment. From the microscopic movements of a single-celled organism toward light to the complex social hierarchies of elephant herds, behavior is the bridge between an animal's biology and its survival in an ever-changing world.
The scientific study of animal behavior emerged in the early twentieth century through the pioneering work of researchers like Konrad Lorenz, Nikolaas Tinbergen, and Karl von Frisch. These scientists recognized that behavior was not merely a byproduct of anatomy and physiology but a fundamental biological phenomenon worthy of rigorous investigation. Their work laid the foundation for our modern understanding of how behavior evolves, develops, and functions in the natural world.
