      Excerpt:

      "How a changing climate can affect ecosystems is an important and
      timely question, especially considering the recent global rise in
      greenhouse gases. Now, in an article published online on December 20th
      in the journal Current Biology, evolutionary biologists provide strong
      evidence that changes in global carbon dioxide levels probably had an
      important influence on the emergence of a specific group of plants,
      termed C4 grasses, which includes major cereal crops, plants used for
      biofuels, and species that represent important components of
      grasslands across the world."
