Scientists think that this species dates all the way back to the Late Pleistocene era; about 300,000 years ago, meaning that it would also be a species that survived the Ice Age.
The Timber Wolf, aka Canis Lupus, is an animal which used to be really abundant over Eurasia and North America, however due to destruction of their habitat by humans, and interaction between humans and the wolves, they are now endangered, however, are not classified as such. They are protected in some areas, but due to their history with humans and their affinity to carry disease, most areas have not raised enough concern to consider them endangered, and if they don't soon, it might be too late to save the species as a whole.
This wolf can carry diseases such as brucella, deerfly fever, leptospirosis, foot and mouth disease and anthrax. ... continue below the picture...
... They also can carry rabies as they can catch it from other species. If one of these wolves does catch the disease, they can become extremely violent and can attack humans if approached. A rabid wolf bite can be treated, but sometimes they can still kill if the person is not vaccinated in time.
These factors and a history of being a nuisance to farmers and even people living in towns, has given these wolves very little protection from human harm.
