Scientific Name: Canis Lupus Arctos Evolutionary History The arctic wolf, canis lupis arctos, is a close relative of the grey wolf, canis lupis. The grey wolf is believed to have originated in Asia, but migrated across the Bering Strait millions of years ago and came to inhabit North America. The Arctic wolf is believed to have originated from grey wolves that migrated to the far north and evolved to better fit that harsher environment. Cladogram The artic wolve's closest relative is the grey wolf (canis lupus). They are mostly related due to they are almost exact in shape. Their bones are identical and they act alike. Fossil records show that ancestors of the arctic wolf are almost exactly like the grey wolf. Adaptations Over time whilst living in their harsh habitat, arctic wolves went through many changes, or adaptations, so that they can live and prosper in their habitat. With a shorter muzzle, there is a smaller surface area from which to lose heat. Most of the arctic wolf's adaptations are related in one way or another to retaining heat, so that it can better survive in its environment They developed a shorter muzzle. They developed a thicker layer of fur. With more fur, this gives them a better chance to survive in thier cold climates. Conservation Issues Arctic Wolf Conservation Status
