Biology Animal Behaviour Introduction

Levels of Analysis in Ethology Proximate CausesUltimate Causes Genetic/Developmental Mechanisms Sensory/Motor Mechanisms Historical Pathways Selective Processes -effects of heredity -development of sensory- motor systems -gene-environment interactions -nervous systems for stimulus detection -hormone systems for adjusting response levels -muscles for carrying out responses -adaptive context ? -evolutionary development of a trait How? Why?

Scientific Method Make Observation Formulate hypothesis to explain observation Test HypothesisPassFail Hypothesis Theory Test Theory Theory Law PassFail Pass Many

The Scientific Method Tinbergen's Observations on the Bee Wolf - Philanthus triangulum 6. Confirm hypothesis  1.Observation - Female flies in a circle before going to hunt. 2. Hypothesis - Female is using landmarks to find the nest. 3. Prediction - Female will return to a landmark to find the nest. 4. Test - Place an artificial landmark around the nest and move it when the female is away 5. Result - Female orients to new landmark.

First Representations of Animal Behaviour

Greek Philosophers Aristotle ( BCE) Perfect ‘Type’ e.g.

EthologyPsychology - origins in natural history - origins in physiology & medicine -early focus -understanding adaptive value of behaviour in the wild -early focus -understanding causation and motivation of human behaviour using animal models - field-based- laboratory-based COMPARISON OF ETHOLOGY AND PSYCHOLOGY - initially more observational- initially more empirical
