<span>Humans have pores in their skin to sweat and cool off the body. Plants have similar structures called stomata. Through these structures, plants can do the same things humans can through their pores, such as release the heat from them, as well as unnecessary chemicals through "sweating."

Microevolution is a change in allele frequencies and can be caused by mutations, selection (natural and artificial), gene flow or genetic drift.
What's different from macroevolution is that this change happens over a shorter time when compared to macroevolution which is when big differences in the population happen.
From the options, a change in the colors of fethers seems like a microevolution that happened due to a mutation in the population over a period of time.
