Darwin would explain step I of natural selection as:
**B: In any population, genetic variation exists.**
This is a fundamental concept in Darwin's theory of evolution, as genetic variation is necessary for natural selection to occur. Without variation, there would be no differential survival or reproduction among individuals in a population, which is essential for the process of natural selection to lead to evolution over time.
