Document Summary

Niko tinbergen, konrad lorenz, and karl von frisch won the nobel prize for their roles in pioneering the study of animal behaviour under natural conditions. Carl von hess, in the 1900s, claimed that bees are colour blind by doing experiments. Behaviour is determined by a complex interplay of the nervous and endocrine systems, by the environment, and by natural selection. When we explore animal behaviour, we ask why an animal exhibits a certain type of behaviour. Tinbergen broke the question down into 4 questions that focus on the behaviour. Causation and development are mechanistic explanations for behaviour they are proximate explanations since they deal with how the behaviour came to be. Adaptive function and evolutionary history provide evolutionary explanations of how natural selection has shaped a behaviour over time they are ultimate explanations of behaviour because they deal with why the behaviour came to be. Answers to his questions rely on an interplay between genes and environment.
