genetically engineered

Scientists have successfully genetically engineered black wolves. At first they thought it was a mistake but since the global warming is melting all the snow the black fur has become more common in wolf packs,  because snow-covered  environments are shrinking and darker coloring allows for the black wolves be camofolged with while hunting in areas without snow. While gray wolves can be found in colors ranging from white to gray to black, light-color is  found in the arctic tundra where wolves prey on  ground caribou. The researchers note that the relationship between coat color and habitat is often linked to adaptation and natural selection, but this is the first example of a genetic modification that likely due to humans becoming more adapted and selected for when back in nature.
