[6] By the 21st century, adaptation to life in cities had markedly reduced the antipredator responses of animals such as rats and pigeons; similar changes are observed in captive and domesticated animals. [79]

Adaptive melanism has been shown to occur in a variety of animals, including mammals such as squirrels, many cats and canids, and coral snakes. Adaptive melanism can lead to the creation of morphs , a notable example being the peppered moth , whose evolutionary history in the United Kingdom is offered as a classic instructional tool for ...

He describes it as a device "perhaps unrivalled" for effective concealment, and points out that it is brought about and depends on "highly ...
