Features
COEVOLUTION – Biologists view coevolution as a major player in the organization of the earth's biodiversity.

It's a topic that John Nason, associate professor in the Department of Ecology, Evolution and Organismal Biology, and his research team and colleagues have been studying in the Sonoran Desert in northwestern Mexico. Nason and a collaborator from Virginia Commonwealth University are using a three-year, $350,000 National Science Foundation grant awarded last year to support the research.

Coevolution is reciprocal evolution resulting from the interactions between species over a long period of time. As one species evolves, it spurs an evolutionary response in other species and vice versa.

For example, Nason explained that the larvae of butterflies that attack a certain plant species for food will evolve in response to evolution in the plant (which might develop defense chemicals) to ward off such an attack.

"A different type of example is a mutualistic interaction, in which interacting species benefit, such as when an insect pollinates a plant in exchange for nectar or other floral rewards.”
