"The wolf is an intelligent and cultural animal. Its behaviour is not just imprinted in its genes, but is also taught from mothers to pups according to circumstance. It knows that a man with a pitchfork is dangerous, and that a man with a gun is even more so. The wolf was different once, and was more active during the day. Its [modern] nocturnal activities are an adaptation against danger. If people completely left wolves alone, in just one lupine generation (that is, five years), the wolf could once again try and attack people, at least in areas where it can allow itself to do so. We have signs of this in Canada, where three cases have been brought to our attention. In Europe, there have been no similar incidents, for now."
