Black-coated animals were found to have 18 percent lower heat loss in temperatures below −10 °C (14 °F), a 20 percent lower metabolic rate, and a non-shivering thermogenesis capacity that is higher than a gray morph. [14] Additionally, researchers of the color morph have noted a strong negative correlation with the frequency of black ...
The opposite of amelanism is melanism, a higher percentage of melanin. [citation needed] A similar condition, albinism, is a hereditary condition characterised in animals by the absence of pigment in the eyes, skin, hair, scales, feathers or cuticle. [1] This results in an all white animal, usually with pink or red eyes.

[ 1 ] [ 2 ] [ 3 ] In 1978, Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
