The best-known examples of natural selection in the modern world are where people have set out to kill members of other species en masse, and those species have pushed back: antibiotic resistance in bacteria; insecticide resistance in mosquitoes; herbicide resistance in weeds. These are well studied because cause and effect are clear, and the consequences are serious for humanity. But people can create evolutionary pressures accidentally as well as deliberately, and Charles and Mary Brown of the Universities of Tulsa and Nebraska-Lincoln have discovered an intriguing case in a population of vertebrates: American cliff swallows.
