Answer:
D. A beetle who adapted to its environment and was able to camouflage itself
Explanation:
According to Charles Darwin, the adaptation and strive for survival in species is the motor of evolution. The species evolve in a series of adaptations over time and transmit these changes to their offspring who in their turn in generations suffer from mutations.
For tha case of the beetle, the capacity to adapt to the hostile environment is the main challenge , as environment reprensents a threat together with other preys but if is capable of camouflage then it ensures protection against them.
The more mechanisms a biological species develops, the better odds to survive. The adaptation to the environment and to external threats as preys and scarcity of food makes the most powerful forces of evolution of species.
