A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought.
Research published in the April 15 issue of the Journal of the American Chemical Society shows that cheatgrass biochemistry is better suited to elevated carbon dioxide concentrations than soybean biochemistry.
