Which type of interaction would be least likely to lead to coevolution of the interacting species?

Question

Quizplus · Accepted Answer

Commensalism is an interaction between two organisms where one benefits and the other is not affected. As there is no significant impact on the host species, coevolution is less likely to occur in this type of interaction. In all other types of interactions listed - mutualism, parasite-host, predator-prey, and plant-herbivore, there is a higher likelihood of coevolution due to the reciprocal selection pressures placed on both species involved in the interaction.
