Step-by-step explanation:
Inherited variation
Natural selection is a process that occurs when certain inherited traits or variations of a species give certain individuals an advantage in their ability to survive and reproduce in a given environment. Therefore, for natural selection to occur, there must be inherited variation within a population. Other conditions such as unlimited resources, a static environment, and a long life span do not necessarily have a direct impact on natural selection. However, these factors can affect the relative fitness of individuals with different inherited variations and thus influence the outcome of natural selection.
