For hundreds of years now Wolves came in two primary colors, white and gray due to adaptation and natural selection. These colors enabled the wolves to easily blend into the tundra atmosphere of the snow and rocks. It also allows the wolves to be able to hunt caribou without being noticed But with global warming the Arctic has been warming up and the colors of the environment are changing. Therefore humans came in and changed the genetic diversity, and breed a wild wolf with a domesticated dog. This then lead to the creation of a third color variation of a black wolf. "With tundra habitat expected to decline in coming years due to northern expansion of boreal forests related to global warming, the researchers note that black coloration may also help wolves survive in a changing environment."
