What best describes coevolution?

Coevolution is best described as a mechanism where the evolution of one organism influences the evolution of another. This concept highlights the interdependent nature of species interactions; for example, think about how flowers and their pollinators adapt to each other over time. The traits of a flower—such as its color, shape, or scent—can evolve in response to the preferences or abilities of the pollinators. Conversely, pollinators may evolve to better access nectar or pollen as a result of the structural changes in the flowers they frequent.

This reciprocal influence can lead to specialized adaptations in both organisms, increasing their chances of survival and reproduction. It emphasizes the dynamic relationship between species, rather than just focusing on how a single species reacts to its surroundings or evolves in isolation, which is a key aspect of coevolution.

Other definitions provided do not capture this interaction properly, as they either focus solely on singular adaptations or on concepts that do not pertain to the specific evolutionary relationships that characterize coevolution.
