The module introduces the basic principles of animal behaviour (ethology), by considering Tinbergen's four questions, with a focus on the mechanisms and ontogeny of behaviour. The importance of adopting an objective approach to the description and interpretation of behaviour is emphasised.

The module discusses the basic principles of ethology under four headings: causation of behaviour, development (ontogeny) of behaviour, evolution of behaviour and function of behaviour, i.e. Tinbergen's four questions: what causes behaviour, how does it develop during ontogeny, how did it evolve and what is its function (adaptive significance). The main focus of the course is on the development and causation of behaviour with discussion of the genetic basis for behaviour, hormonal influences, physiological mechanisms involved and the motivation for and maturation of behaviours. Topics covered include phylogeny of behaviour, genotypic influences on behaviour, sensory adaptations and stimulus filtering, effect of hormones on behaviour, models of motivation and learning. Scientific methods for investigating behaviours are also discussed. The relevant text is Barnard (2004).
