In science, a model is a system that is close enough to reality that one can learn something useful from it. It is almost always cost-effective to use models rather than the real thing as a test bed, even if the differences sometimes lead to misleading results. Medical and life science researchers put a great deal of effort into producing animal models of human diseases, a way to explore causes and treatments within available budgets. In some cases this is just a matter of standardization, as a given condition with very similar mechanisms exists in multiple species besides our own. In others, such as Alzheimer’s disease, the models must be highly artificial, as none of the relevant mechanisms of the human condition exist naturally in the
