Bats have evolved to use echolocation (emitting high-frequency sounds & listening to the returning echoes) to catch their prey. Some species of moth can perceive the high-pitched echolocation noise emitted by bats, helping them avoid becoming easy prey. This case is an example of _____.

• A. Competitive exclusion.
• B. Camouflage.
• C. Mimicry.
• D. Coevolution.

Answer: (D)

Verified step by step guidance

1. Identify the key biological interaction described in the problem: bats using echolocation to catch prey and moths perceiving these sounds to avoid predation.
2. Understand the concept of coevolution: it refers to the process where two or more species influence each other's evolutionary pathway, often due to close ecological interactions.
3. Recognize that in this scenario, the evolutionary pressure exerted by bats on moths (and vice versa) leads to adaptations in both species. Bats evolve better echolocation abilities, while moths evolve better detection mechanisms.
4. Differentiate coevolution from other concepts: Competitive exclusion involves species competing for the same resources, camouflage involves blending into the environment, and mimicry involves one species evolving to resemble another.
5. Conclude that the interaction between bats and moths, where each species evolves in response to the other, is a classic example of coevolution.
