Testing on animals is very important thing to do in the medical field to cure diseases. Since I was a child, I believed that each creature on this earth is existed for a purpose. When I was in middle school, my teacher made me anatomized a rabbit to see how its organs are similar to human's organs. This experience is what made believe that animals are not only exist to complete the ecosystem, but also to help in finding cure for many different diseases. 

I am really interested in how animals testing can help in improving medical field. I have read articles and made some researches about animal's experiments which showed me evidence on how efficient these tests are. 

The first article I read talks about two main majors. The first major is how animal testing is saving lives. The second major is how animal experiments will make a better future in beating cancer.  The claim of this article is to show how experiment on animals has helped in beating many kinds of cancer. The first main point in this article is answering my research question. It discusses studies and show examples in the efficiency of these tests. For instance, tamoxifen drug was improved by animals testing to cure breast cancer which saved a lot of women lives. 

Dr.David Scott, the director of science funding and the one who wrote about this article. Being a doctor who has done many kind of researches and showed studies about this topic, he definitely has credibility. He talked in a biased way because he only presented the benefits of animal testing.

The second article discusses two main points only. The first point is, the pros of animal's research in the medical field. This point talks about finding drugs to improve people's health and to find new methods in treating humans. The second point which is the cons of animals testing on animals. This point talks about the differences between animals and humans, how inhuman scientists are, and also how expensive it is.

Ian Murnaghan BSc, is a scientific writer who wrote a lot of articles in many different areas including medical area and he is also the writer of this article. Ian has credibility in his writing because he is showing evidence and studies that prove his perspective. In addition, he is unbiased because he presented both perspectives of animal's research.

The third article which is the final one explains three main majors. The first one, research on animals will make scientists understand the living system which includes cells, tissue, and organs. The second Point, animals help in seeing the reaction of stimuli on humans. The third point, animals are similar to human biologically and they share 200 similar health problems.

The third article was written by an organization called "Americans Medical Progress" which is a known website and has credible articles because it presents statistics and studies. The organization is biased because it only talked about the efficiency of animal testing. 

There are a lot of people who disagree with my research question "How can animal testing help us in Medical Field?" It is a controversial topic. One of the sources I disagree with is the second article which talk about the negative effects of animal testing. They say that one of the cons is being inhuman. In my perspective, people who disagree with animal research because of this reason are thinking emotionally. They need to think in a rational way with their brain not their heart so that people lives improve in a better way. I would not revise my question because I have good sources, but I will try to find more sources to support my research question.
