Answer 1

This scenario demonstrates evolution through advantageous traits because:

Darker shells are harder for predators to see.

In a dark shaded forest, dark-shelled beetles have better camouflage, making them less visible to predators. As a result, they are more likely to survive and reproduce, leading to an increase in the population of dark-shelled beetles over generations. This illustrates natural selection, where advantageous traits (in this case, darker shells) become more common in the population.
