उत्तर
Natural selection is best defined as occurring when the environment causes differential success in reproduction.
Explanation:
Natural selection is best defined as the process by which the environment causes differential success in reproduction among individuals with different heritable traits. Those individuals whose traits are better suited to the environment tend to leave more offspring, leading to changes in population traits over time. This differential reproductive success drives the evolutionary process.
