Natural selection is when favorable traits stay in a population while unfavorable traits get weaned out. EX: There is terrain that is lightly colored and there are some moths there. They need to blend into the terrain to not be eaten by birds. So, the lighter colored moths live longer and can produce more offspring than the darker colored moths. Now, what happens if the color of the terrain changes due to a factory being put right next to it and causing the terrain to turn grey. The lighter colored moths will be eaten more than the darker colored moths so then he darker colored moths will be reproducing more and most of the moths will be darker colored.
