How cool is this? A species of pea aphid appears to have picked up the genes for making carotenoids from fungi–making it the first known animal to manufacture their own. This adds to the evidence that DNA can transfer laterally from bacteria, yeast, or fungi to animals. The evolutionary story is just getting more and more interesting!
