Ethology is the study of animal behavior, especially in natural conditions. It took shape in the 1930s through the work of Konrad Lorenz, Niko Tinbergen, and Karl von Frisch, who shared a Nobel Prize in 1973. They insisted that behavior should be observed in the field, not just in laboratories. Their work on imprinting in ducks, bee communication, and instinctive fixed action patterns laid the foundation for the field.

Ethologists ask how behavior develops, what triggers it, how it evolved, and what function it serves. These four questions, formulated by Tinbergen, remain a core framework. The field overlaps with comparative psychology, behavioral ecology, and evolutionary biology. It has also influenced anthropology, particularly in debates about human nature and the biological roots of social behavior.

Classic findings

• Imprinting: young birds follow the first moving object they see.
• Fixed action patterns: stereotyped responses to specific signals.
• Honeybee waggle dance communicates direction and distance.
• Territoriality and courtship rituals across many species.

Ethology reminds us that humans are animals too, and that some of our social tendencies have deep evolutionary roots.
