Why do universities experiment on animals?

Answer 1

Experiments are done on animals for the same reason that any kind of experiments are done, which is either to get experience with the process of experimentation, or to seek new knowledge. There are many important questions that arise about human Biology which cannot be investigated through experiments on people for obvious ethical reasons, and which therefore are investigated by experiments on animals. Animal experimentation also raises ethical issues, however, many people believe that the knowledge gained is worth the cost.
