Yes, the given information offers an explanation of how and why the dark peppered moth increased in the population. This situation exemplifies the theory of natural selection because it illustrates a change in allele frequency in response to environmental pressures. The dark-colored moths had a survival advantage in polluted environments where their coloration provided better camouflage, leading to increased reproduction and survival.
The peppered moth (Biston betularia) is an insect common to Europe and North America and has two phenotypes, light-colored and dark-colored. Before the Industrial Revolution in the UK, the light-colored moth was more common, but as industrialization went on, forests became polluted and trees darkened. Light-colored moths became more vulnerable to predation than before, while dark-colored moths could evade predation, survive, and reproduce. As a result, the frequency of dark-colored moths increased to represent more than 80% of the population by 1959.
Given this information, would the peppered moth be an example of the theory of natural selection? Why or why not?

The true statement is: There was a consensus among scientists that miasma caused diseases before the 19th century.
Before the germ theory of disease became widely accepted, the prevalent belief was that diseases were caused by "miasmas," or bad air. It wasn't until the latter part of the 19th century that the germ theory gained consensus among scientists, led by the work of researchers like Louis Pasteur and Robert Koch.

The phrase that best describes this situation is scientific controversy.
This term is appropriate because there are conflicting explanations from different scientists regarding the cause of the animal adaptation, indicating a debate or disagreement within the scientific community.
