Animal research is a scientific process that involves studying animals in order to understand their biology, behavior, and genetics. This type of research is often used in the fields of biology, psychology, and medicine to develop new treatments and cures for diseases, as well as to learn more about the natural world and how it functions. Animal research can involve a wide variety of methods, from observing animals in their natural habitats to conducting experiments in a controlled laboratory setting. Critics of animal research argue that it can be unethical and inhumane, while proponents argue that it is necessary for advancing scientific knowledge and improving human health.
