Peppered moths use the adaptation of camouflage as protection from predators. they may have a variety of colors or shades, but before the industrial revolution, they were typically white with black speckles. the industrial revolution in the 1880s introduced large-scale pollution into the environment. the pollution resulted in widespread, dark-colored staining of buildings and trees.

which of the following was the most likely effect of the industrial revolution on peppered moths in cities?

a.
the peppered moths developed a tolerance to smog and chemical waste.
b.
over time, the white, speckled moths were outnumbered by plain white moths.
c.
the population of light-colored moths decreased and the population of dark-colored moths increased.
d.
the peppered moths adapted an improved sense of sight and smell.

The answer is; C

This is due to natural selection that is the basis of evolution.  The light-colored moths became conspicuous to its predators in the dark environment. The black moths on the other hand camouflaged and were preyed on less. This allowed black moths to have an increased chance, compared to light-colored moths, of reaching reproductive age and passing their genes to the next generation.
