Verified step by step guidance1
Understand that the peppered moth (Biston betularia) is a classic example used in genetics and evolutionary biology to study natural selection and polymorphism.
Recognize that the term 'carbonaria morph' refers to a specific genetic variant or morph of the peppered moth.
Recall that the carbonaria morph is known for its dark coloration, which historically increased in frequency during the Industrial Revolution due to pollution darkening tree bark.
Identify that the typical wing color of the carbonaria morph is black, which provides camouflage against soot-darkened surfaces.
Conclude that among the given options (Black, White, Gray, Brown), the correct wing color for the carbonaria morph is Black.
