Solution
As a mechanism of microevolution; natural selection can be most closely equated with differential reproductive success.
Explanation:
As a mechanism of microevolution, natural selection can be most closely equated with differential reproductive success. This means that individuals with favorable traits are more likely to survive and reproduce, passing those traits on to the next generation, which leads to changes in allele frequencies within the population over time. It is distinct from assortative mating, genetic drift, and gene flow, which are distinct mechanisms that affect genetic variation and population genetics.
