> If we exclude the humans, the wolf is the animal that had saved more human lives in the history

Would you mind elaborating on this point? In what way has the wolf saved uncountable human lives? I've only ever seen it portrayed as a human and livestock predator.

EDIT: I've been reading up on the matter. Historically, the wolf has been associated with disease control, as they tend to remove the weakest, sickest members of a given herd from the genetic pool.
