Final answer:
Genetic drift is not a potential agent of selection in evolutionary biology.
Step-by-step explanation:
In the context of evolutionary biology, genetic drift is NOT a potential agent of selection. Genetic drift refers to random changes in gene frequencies in a population, which can occur due to chance events and not based on the fitness of individuals. Unlike natural selection, which results in the adaptation of a population to its environment, genetic drift does not lead to the survival of the fittest and is not a deliberate process.
