Animal Behavior (Ethology)

The field of ethology was pioneered in the 20th century by three prominent scientists: Konrad Lorenz, Niko Tinbergen, and Karl von Frisch. They were jointly awarded the Nobel Prize in Physiology or Medicine in 1973 for their discoveries concerning animal behavioral patterns.

Niko Tinbergen established four distinct questions to explain animal behavior, categorized into proximate (mechanism and ontogeny) and ultimate (survival value and phylogeny) causes. These questions are still the foundational framework used in modern ethology to understand why animals act the way they do.

Imprinting is a biological phenomenon famously studied by Konrad Lorenz, where a young animal forms an irreversible attachment to the first moving object it sees after birth. This is most commonly observed in greylag geese, which will follow a human instead of their mother if exposed to the human first.

Ethology traditionally focuses on observing animal behavior in their natural, wild environments to understand instinctual and evolutionary traits. Comparative psychology, pioneered by figures like B.F. Skinner, tends to study animals in controlled laboratory settings to understand basic learning mechanisms.
