The correct answer is D. A butterfly predator sees yellow more easily than it does green, and a population of butterflies includes both phenotypes.
Explanation:
Evolution occurs due to the selective force of nature. So here the selective force is a predator and the population which is more adapted to their environment will be selected over less adapted population.
So as yellow can be seen more easily than green, therefore, chance for picking yellow butterfly is more than the green. So as green butterflies have required adaptation or traits that help them to protect against predator, therefore, it will lead to their evolution.
Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanicrocks that are exposed at the Earth's surface to determine the relative agesof geological events preserved in therock record.
