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
1 answer
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.
