"ANN ARBOR, Mich.—Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.

"The research focused on the effects of elevated carbon dioxide on common milkweed, Asclepias syriaca. Milkweed is one of many plants that produce toxic or bitter chemical compounds to protect themselves from being eaten by insects. These chemical defenses are the result of a long history of interactions between the plants and insects such as monarch caterpillars that feed on them."

You'd expect climate change, which has always driven evolution, to have an effect now. Only problem is most species can't evolve quickly enough, if all the past mass extinctions are anything to go by
