Document Summary

Ethology: study of animal behaviour from an evolutionary prospective. Scientists use many ways to see why organisms do what they do, for example: Deprivation experiments: what is genetically coded and what is learned from the environment. Genetic experiments: selective and inter breeding, gene knockouts. Genetic control does not have the external environment to rely on, not as flexible. Learning from the environment is more flexible, but it is vulnerable to making mistakes or incorrect info. Even genetically controlled behaviours aren"t always hard wired; sometimes they need a cue to start certain behaviours. Releaser: an object, or condition required to elicit behaviour. Environmental control is always good to have because the environment is always changing and therefore we can learn on the go. Food choice is a very important behavioural response that directly effects animals fitness. Animals can get essential minerals, can stay away from toxins, and consume the antimicrobial properties, also calories.
