In an ecosystem, there are two color varieties within a species of toads, brown and green, over 50 years the proportion of the population that is green increases from 20 to 50% which statement is the most likely to explain this change
The most likely explanation for the increase in the proportion of green toads in the population over 50 years is natural selection. Green toads may have a survival advantage over brown toads in the ecosystem, such as better camouflage or increased resistance to predators, leading to their increased proportion over time.
