Most testing is done on mice and rats, which do not seem to have many similarities with humans. In fact, however, humans and mice share about 88% of the same genetic makeup, making them excellent candidates next to chimpanzees, who share about 90% of the same DNA as humans (“New”). Mice and rats are easily accessible and abundant. They are small, easy to shelter and maintain, and adapt well to new surroundings. They also reproduce quickly and have a short lifespan of two to three years. This is a benefit in the science community because several generations of mice can be observed in a relatively short period of time, making long term testing easier (“Melina”). In the field of medicine, animal testing works better than any other method because vast amounts of research cannot be done on humans. Animals are similar to humans in their genetic makeup, making them excellent research candidates. …show more content…
Animals have been studied, probed, observed, and made into models. In order to understand the human brain, animals are used as pre-models that are then tested like a human’s. Animal testing in the field of psychology has shed light on human emotion and brain function as well. A famous study by Ivan Pavlov used a dog to introduce the idea of conditioning, which was then applied to humans. This idea brought about different thoughts on learning, cognitive process, and more within people. Knowledge concerning different types of personality and brain disorders have also been improved, including the areas of Alzheimer’s, schizophrenia, neural damage, the body’s response to pain, and addictions. Without the use of animals, we would not have nearly the same amount of vast information regarding these illnesses. Schizophrenia can now be handled with medication, along with many other personality disorders like bipolar disorder and obsessive compulsive disorder. Animals are also used to study the recovery process of many other diseases such as post-traumatic stress disorder, neural degenerative disease, and anxiety. In addition, animals are observed in maternal deprivation, learned helplessness, and response to fear. Much of this directly correlates to human response, bringing about knowledge on all of these issues and cognitive processes (“Cognitive”). Without the use of animals, we
