In an ecosystem, there are two color varieties within a species of totes brown and green over 50 years. The proportion of the population that is green increases from 20 to 50% which statement is most likely to explain this change.

One possible explanation for the increase in the proportion of green toads in the population over 50 years is natural selection. The green toads may have a selective advantage in their environment, such as better camouflage or a higher resistance to predation. This would allow the green toads to survive and reproduce more successfully than the brown toads, leading to an increase in the proportion of the population that is green. Over time, this natural selection process could result in a shift towards a higher proportion of green toads in the population.
