A population of caterpillars feeds on the leaves of trees in a forest and is in turn food for birds that eat them off the tree leaves. Given this information, which adaptation would be most likely to evolve?

A. Birds would evolve to eat more types of insects.

B. Caterpillars would evolve to eat the bark as well as the leaves.

C. Caterpillars would evolve to a larger size.

D. Caterpillars would evolve to a color that matched the leaves they eat.

D. Caterpillars would evolve to a color that matched the leaves they eat.

Explanation:

In addition to the ability of caterpillars to cling in leaves and draw water from them, they are able to camouflage themselves on the leaves depending on their coloration.

Caterpillars can come in many different colors, but most are green or brown, this is an evolutionary response, so caterpillars can be mistaken for the leaves they usually feed on, for the purpose of not drawing attention of predators such as birds, for example. This evolutionary trait will therefore give caterpillars a better chance of survival.

The correct answer is option D. "Caterpillars would evolve to a color that matched the leaves they eat".

Explanation:

Natural selection functions under the premise of survival of the fittest, at which advantageous traits in populations are selected because they are more likely to survive. In this case, caterpillars having a color that matched the leaves they eat would be advantageous for them because it will act as camouflage against birds. Therefore, it is likely that caterpillars will evolve to have this trait because caterpillars with the same color as the leaves will have more chances to survive birds attacks.
