An animal<unk>  (short for<unk>  is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal<unk>  does not ensure an effect in humans, many drugs, treatments and cures for human diseases are developed in part with the guidance of animal<unk> s. Animal<unk> s representing specific taxonomic groups in the research and study of developmental processes are also referred to as<unk>  organisms. There are three main types of animal<unk> s: Homologous, Isomorphic and Predictive. Homologous animals have the same causes, symptoms and treatment options as would humans who have the same disease. Isomorphic animals share the same symptoms and treatments, only. Predictive<unk> s are similar to a particular human disease in only a couple of aspects. However, these are useful in isolating and making predictions about mechanisms of a set of disease features.
