Concept

Problem: One spring, a dust storm blankets the usually green garden where a species of fraggles forage for food in gray dust. Under these conditions, the green fraggles become very visible to the Gorgs, monstrous beasts who tend the gardens and try to kill fraggles to protect their crops. The gray fraggles, however, now blend into the dusty background and find that they can easily steal radishes without detection. How might this affect microevolution in this population of fraggles?a. the gray fraggles will likely become a new species over timeb. the proportion of the gray fraggles will increase in the population over timec. green fraggles learn to forage at night to escape detectiond. green fraggles have more offspring per litter to compensate for their higher mortalitye. green fraggles reproduce more often to compensate for their higher mortality
