Which of the following is NOT an example of natural selection?

Answer 2

The correct answer is A. People breeding dogs to be less aggressive.

Step-by-step explanation:

Natural selection, according to Darwin, is the process by which species adapt to the environment, given certain pressures it might set upon them. The other choices refer specifically to a natural adaptation, such as bacterias becoming more resistant, birds' beaks changing and moths changing to darker colors. However, a person breeding a dog to be less aggressive is not an example of natural selection, given the fact that specific breeding is an artificial method, not relying on the natural changes to adapt to the environment.
