evolution involving a series of reciprocal changes in two or more noninterbreeding populations that have a close ecological relationship and act as agents of natural selection for each other, as the succession of adaptations of a predator for pursuing and of its prey for fleeing or evading.

Fill in the blank: I can’t figure out _____ gave me this gift.
One hurdle for glycobiology, Gagneux noted, is that even closely related species with high levels of genetic similarity, like chimps and humans, have glycans that can vary significantly because of constant, ongoing coevolution.
The evolution of two or more species that interact closely with one another, with each species adapting to changes in the other. The mutually beneficial development of flowering plants and insects such as bees and butterflies that pollinate them is an example of coevolution, as is the mutually antagonistic development of prey and predator species in which defensive adaptations in the one are matched by counteradaptations in the other aimed at neutralizing or overcoming them.
The process that occurs when two species influence each other during evolution. For example, an insect may evolve specialized parts that allow it to feed on a specific flower, whereas the flower evolves to facilitate pollination by that particular insect.
