Answer:
This can be explained by an adaptation process in natural selection, the theory proposed by Darwin.
Explanation:
The adaptation process in the natural selection occurs in a very simple way, let's think about it. First, think of a green forest with butterflies of all colors, including green ones. In this forest, there's a predator of butterflies growing up, and once it starts eating them, it's easier for them to eat the butterflies with different colors. The green ones, in this case, won't be eaten, just because of their color, they can hide easily from the predator, and in this way, the gene for the green color will pass forward.
