The “new peppered moth” example – Black
(Green) Tree frogs from Chernobyl!
Black skin color is created by by pigments known as melanins. The quantity of melanins
present in skin and hair creates darker colors for many animals, including humans. Melanins
are important for reducing the harmful effects of ultraviolet radiation in sunshine — which is
the reason that people develop a tan when exposed to a lot of sun. Melanins also protect
DNA from the damaging effects of ionizing radiation from nuclear disasters by absorbing and
dissipating at least some of the radiation’s damaging energy.
