1. The Industrial Revolution impact on the population of peppered moths in Britain resulted in **the dark-colored moths becoming more common**. This occurred due to increased pollution from industrialization, which darkened tree bark, giving a survival advantage to the darker moths that were better camouflaged against predators. 2. The statement most likely regarding the increase in the proportion of long-tailed squirrels from 10% to 60% is **the proportion of long-tailed squirrels may have increased due to increased food availability**. Long-tailed squirrels may be better adapted for reaching food sources in trees, thus allowing them to thrive and reproduce more successfully as food became more accessible.
