If green insects survive attacks by birds more often in an environment, what may happen over time?
Answer and explanation
Correct answer: The green-colour trait may increase in the population.
If green colour provides camouflage, birds may detect green insects less easily. The insects that survive more often have a greater opportunity to reproduce, and the trait may be passed to their offspring if it is inherited. Across many generations, the proportion of green insects can therefore increase in the population. Option A is correct; natural selection is gradual, does not instantly change every insect, and does not cause birds to lose chromosomes.
