Document Summary
The study of animal behaviour from an evolutionary perspective the hormonal, neuronal, and anatomical mechanisms of a behaviour. An unlearned trait (usually species specific) where individuals of a species performs exactly the same way. Genes do not produce behaviour; rather, the product of genes (i. e. enzymes) affects behaviour by setting forth a series of genetic environment interaction which allows for the appropriate proximate mechanism that allow for certain behaviours to occur. A type of experiment where a young animal is reared so it is deprived of all the experiments needed to perform a behaviour being studied. If the animal picks up the behaviour regardless, then it is stereotypic. Even if a behaviour is not expressed under the deprived state, it may still be genetically influenced. Some behaviours are only expressed under certain conditions, influenced by a releaser. Also, genetic experiments such as selective breeding, interbreeding, and gene knockout experiments also help determine the influence of the environment on a behaviour.
