Jan 06, 2008 – Montana, USA – Alpha male Gray Wolf (Canis lupus) Grey Wolf confrontation with beta male wolf in fresh winter snow, Montana, USA. The grey wolf or gray wolf (Canis lupus), also known as the timber wolf or simply wolf, is the largest wild member of the Canidae family. It is an ice age survivor originating during the Late Pleistocene around 300,000 years ago. DNA sequencing and genetic drift studies reaffirm that the gray wolf shares a common ancestry with the domestic dog, (Canis lupus familiaris) and is probably its ancestor, though certain aspects of this have been recently questioned.
