Animal Testing - Essay Example Animal testing has also contributed to understanding how to treat malaria, Leukemia, and other major diseases that eliminated a very high number of human populations in the past. The animal is the best research subjects because they share similar characteristics with human beings. For instance, Chimpanzees has 99% DNA similarity with humans (Hayhurst, 2000). In addition, mice are almost genetically similar to human beings. Due to these similarities, they are susceptible to the same diseases that affect human beings. There are very many ethical considerations that might be observed when using human subjects. This is mainly when testing medicines that are of high toxin levels. In such cases, the lives of human beings should not be put in any form of danger (Watson, 2009). Therefore, the test of human beings should be preceded by that of human beings.Animals have also benefited immensely in the testing. Many deadly diseases such as rabies, tetanus, anthrax, etc could not have been contr olled if animal testing was not conducted. Moreover, more animals could have been swept off by the diseases and become extinct. As a result, the testing has major benefits on animal species (Watson, 2009). Animals used for testing have a shorter lifespan than human beings. For instance, a mouse has a lifespan of two to three years (Hayhurst, 2000). Therefore, while testing a medicine that affects a whole lifespan of a human being, it’s easier to get quick results when using animals rather than human beings.
