Grey wolf



The grey wolf (Canis lupus) is the largest 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). The range of wolves are from North America and Eurasia.
