Details: This poster shows a black wolf in the snow. At the bottom it says Black Wolf, Wildlife Series .
A Black wolf is a melanistic colour variant of the grey wolf (Canis lupus). Black specimens are recorded among red wolves (Canis rufus), but these are probably extinct. Genetic research has shown that black furred wolves owe their colouration to a mutation that first arose in domestic dogs. Seeing as black coloured wolves occur more frequently in forested areas than on the tundra (black coats occur in about 62% of wolves in the forested areas of the Canadian Arctic, compared with about 7% in the icy tundra), melanism was concluded by the researchers to give those wolves an adaptive advantage. As human hair, dark fur is dominant in wolves.
