This article is a description of the naturalist Charles Darwin and his voyage aboard the H.M.S Beagle. In the article, Quammen talks about theory and explains what it is. He states that Darwinism was just a theory. In the article he talks about how “45% of responding U.S. adults agreed that God created human beings pretty much in their present form at one time within the last ten thousand years” (Quammen, 1). Quammen then begins to present the evidence that Darwin was correct in some of his theories but not all of them. He does this by stating what Darwin based most of his beliefs off of. His beliefs were based solely off of the four fields of study, paleontology, embryology, morphology, and biogeography. Quammen explains that Darwin was wrong in his theory of variation among species, and his theory of inheritance. Being wrong in both of those fields he was correct in the most important aspect of science today, the theory of evolution by natural selection. Throughout the reading he gives example of how accurate Darwin was in his theory. For example, he talks about the growing resistance to drugs that fight off disease in humans caused by bacteria. He explains that the bacteria are like animals in that as they became more familiar with the drug they adapt and change, over a period of time the bacteria are resistant to the drug and a new one must be processed. Quammen gives many more examples of situations like this but this article talks about how Darwin was correct in his theory of evolution by natural selection. The reading in general really persuades the reader that Darwin was correct in his theory and that there is no sole evidence that could deny his beliefs.
