- Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. The activity of each species that participates in the interaction applies selection pressure on the others.
These ecological relationships include:
(i) Predator/prey and parasite/host
(ii) Competitive species
(iii) Mutualistic species - Predator/prey and parasite/host: In a predator-prey interaction, for example, the emergence of faster prey may select against individuals in the predatory species who are unable to keep pace. Thus, only fast individuals or those with adaptations allowing them to capture prey using other means will pass their genes to the next generation. Both intraspecific competition (whereby members of the same species compete for limited resources), with features such as sexual conflict and sexual selection, and interspecific competition (in which individuals of different species compete for the same resources), such as between predators, may be able to drive coevolution.
- Mutualistic species: Plants and insects represent a classic case of mutualistic coevolution. Many plants and their pollinators are so reliant on one another and their relationships are so exclusive that biologists have good reason to think that the "match" between the two is the result of a coevolutionary process.
- Commensalism: An association between two organisms in which one benefits and the other derives neither benefit nor harm. It does not involve much physiologic interaction or dependency between the two partners, the host and the commensal. The two partners can survive independently. It does not promote coevolution. Hence option (d) is correct.
