The researchers become more knowledgeable about the human anatomy by doing tests on the animals. Also, the researchers were able to improve their surgical skills. By experimenting and researching on animals, they can concentrate and conjure up new ways to surgically help a human patient. Surgical practices have been drastically improved since animal experimentation became popular. Although it is clear that by performing experiments on animals is beneficial to the human race, it is just as clear that the animals are suffering greatly as a result of these experiments.
Animal experimentation is often painful and has been known to cause death.
They should not have to undergo such extreme torture, simply for the sake of helping find a new vaccine. During earlier testing, researchers wanted to learn more about the process of swallowing. The beating of the heart was another function that seemed interesting to the researchers. They wanted to learn and explore the heart's everyday processes. These two experiments were performed at a time when humans did not believe in using anesthesia to put animals asleep for the process.
