Solution
The correct answer is A: dark moths had a higher survival rate than light moths. This is a reference to the famous example of natural selection observed in the peppered moth during the Industrial Revolution in England. Before the Industrial Revolution, the light-colored moths were more common as they could easily blend with the light-colored lichens and tree barks, hiding from predators. However, as soot from factories darkened these surfaces, the dark-colored moths had a survival advantage as they could better camouflage against the dark background, leading to an increase in their population.

The peppered moth is often used as a case study to illustrate natural selection. The allele for dark-colored is dominant and the allele for light colored is recessive. In the 1850's light-colored moths were higher in population size and easily camouflaged in the trees from predators; however after industrial air pollution covered the trees with soot in the early 1900's the dark-colored moths blended in with the trees more effectively and became greater in number than the light-colored moths. Which evolutionary trend is demonstrated?Group of answer choicesa smaller percentage of light-colored moths survive to reproduce, shrinking the gene pool and causing mutations.the populations of the light-colored and the dark-colored moths will both become extinct.more dark-colored moths survive to reproduce, which shifted the allele frequency towards the dark-colored allele.over time, the birds will get used to eating the light-colored moths and stop eating the dark-colored moths.
