Question

A biologist observes that a stick insects on a remote island has three different color traits, almost equally distributed among the population. One phenotype is dark green, a second is light green, and a third is is light green with dark green stripes. Over a decade, the biologist observes the dark green phenotype becomes the most abundant l, making up nearly 70% of the population.

Answer 1

I would say that the dark green color helps benefit the insects' survival. Some studies state that the population would probably become extinct if there were no creature variations, which would allow them to hide from predators and blend in with their surroundings in many cases.
