Biologists experimentally trigger adaptive radiation

Preening drives divergent camouflage in feather lice on both micro- and macro-evolutionary timescales Using host-specific parasites isolated on individual pigeon ‘islands,’ the scientists showed that descendants of a single population of feather lice adapted rapidly in response to preening. They found that preening drives rapid and divergent camouflage in feather lice transferred to different colored … More Biologists experimentally trigger adaptive radiation
