What is the cause-effect relation between adaptation and natural selection?
Answer and explanation
Correct answer: Adaptive traits benefit organisms, and natural selection can increase them in a population.
The governing concept is natural selection acting on heritable variation. An adaptive trait gives some organisms an advantage in survival or reproduction under particular environmental conditions. Those organisms are more likely to leave offspring, so the associated trait may become more common over generations. Natural selection does not create every adaptation instantly or remove useful traits; therefore option A correctly describes the relation.
