This Is A Truly Lousy Experiment About Evolution
In a simple experiment, Sarah Bush and Scott Villa placed feather-eating lice on different-colored pigeons and left them there to breed and evolve—for four years. Feather lice are small, wingless insects that spend their whole lives among the plumage of birds, eating feathers and flakes of skin. The lice, in turn, hide through camouflage: In 2010, Bush and her husband, Dale Clayton, showed that lice tend to match the color of their host’s feathers.
