Document Summary
Anything organisms do that involves action in response to internal or external stimuli; the response of an individual, group, or species to its environment. Such responses may or may not be deliberate, and they aren"t necessarily the result of conscious decision making. Horse doesn"t deliberately throw you off when it feels scared. One of the major goals of primatology is to discover how certain behaviours influence reproductive fitness and how ecological factors have shaped the evolution of those behaviours. Study behaviour from and ecological perspective (relationships between organisms and all aspects of their environment) Approach is called behavioural ecology study of evolution of behaviour emphasizing the role of ecological factors. Based on the underlying assumption that all of the interconnected biological components of ecological systems evolved together. Behaviours have evolved through the operation of natural selection. Behaviour constitutes a phenotype, and individuals whose behavioural phenotypes increase reproductive fitness will pass on their genes at a faster rate than others.
