Quizplus · Accepted Answer

Resistance to DDT in insects is a classic example of natural selection. When DDT was first introduced, it killed most insects. However, some insects had genetic mutations that allowed them to survive exposure to DDT. These insects had a selective advantage and were able to reproduce and pass on their resistance genes to their offspring. Over time, the frequency of resistance genes increased in the population, leading to the development of DDT-resistant insects. This is natural selection in action. The other options are not supported by scientific evidence.
