In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.
