Areas of Research that Use Animals
Given the prevalence of research that has relied on the use of animals, it would be almost impossible to find an area of investigation that has not used any animals. Because so many species of animal exist to experiment on, researchers can pick and choose whatever species serves their need and “proves” their hypothesis, and enables their work to be published.

To get a better idea of the role of animals as human disease models and to examine the contribution of non-animal models, let’s focus on a few selected diseases:
