The theory of evolution by natural selection gained rapid acceptance among biologists after Darwin published it in 1859, in part because it was so successful in explaining what we see in the fossil record. The theory of evolution has gained even further support since that time, because it has successfully passed many other observational tests. Which of the following statements represent successful tests of the theory of evolution by natural selection?
•Over time, bacteria tend to acquire resistance to antibiotic drugs.
•Species often show unique adaptations that are suited to the specific environment in which they live and might be detrimental in other environments.
•Genetic comparisons show that the DNA of closely related species is more similar than that of more distantly related species.
