The scenario demonstrates evolution through advantageous traits because **darker shells are harder for predators to see**. In a dark shaded forest, beetles with darker shells are better camouflaged, which reduces predation and allows them to survive longer and reproduce more effectively than lighter-shelled beetles. This leads to an increase in the population of dark-shelled beetles over generations due to the advantageous trait of improved camouflage.
