In 1809 Charles Darwin was born. As a young adult, Charles Darwin longed to be a clergyman despite the fact that he considered himself a naturalist. Animals fascinated Charles Darwin, especially if they were similar but had different traits. Darwin always wondered where and how such creature came to be.

In Darwin's Dangerous Idea, it was said that animals are “chosen by nature to survive” some organisms die in the certain atmosphere because they don’t have the traits to help them survive the conditions in the environment placed. For example, polar bears have a thick and dense fur which helps them stay warm in cold weathers.

This makes it harder for scientists to know how to attack the virus. In the video Darwin's Dangerous Idea 2002 it was said that if you take the patient off medications against HIV, hopefully, the virus will revert back to the state where it’s not resistant to medications and then attack it with harder
