Question

station #5
prior to the industrial revolution, the
majority of peppered moths in england
had light-colored wings, which helped
them blend into the light-colored tree
trunks where they rested during the day.
however, with the rise of industrial
pollution, tree trunks became darkened by
soot. some moths had a mutation that
caused their wings to be darker, creating a
survival advantage as they were less visible
to predators. over time, the population
shifted, and the dark-colored peppered
moths became predominant than the
light-colored moths.

Explanation:

This problem describes the change in peppered moth populations due to environmental changes (industrial pollution darkening tree trunks) and natural selection (darker moths having a survival advantage). This is a classic example studied in Biology, specifically in the subfield of Evolution (a part of Biology) as it involves how a species' population changes over time due to selective pressures.

Answer:

The subfield is Biology (specifically related to Evolution and Natural Selection within Biology).
