Document Summary
Behaviour precedes the evolution of many anatomical and physiological features eg. locomotion change. What controls, elicits, or modi es the expression of a behaviour. What is the outcome within the lifetime of an individual. What is the selective advantage that has resulted in the evolution of this behaviour. How does this behaviour increase survival and reproduction. Correlations of behaviour with environmental variables (proximate) Comparative analyses of behaviour across species and measured survival and reproductive success. Will have both explanations for all behaviours. Shoe could it have evolved to work that way. Low energy, hungry, nd food and ingest it to increase energy levels. Low energy, more likely to die and less likely to reproduce. Individuals who responded more quickly to cues of hunger are more likely to survive and reproduce. Social environment - other humans around, interactions with others. Selective advantage of a behaviour is context dependent.
