I believe the reason we don't see many reports of "Wild Men" is due to people grabbing the term "Bigfoot" as an alternative. The reason we don't see many reports of Bigfoot in the papers is probably due to the fact that we have become jaded as a culture to this now. There have been so many reports over the past decades that we aren't intrigued by it any longer. Back in the 1800's and early 1900's the mind was titillated by the thought that there could be a "Wild Man" running around in the forest or woods. Who was he, where did he come from...things like that. These days we just figure it is a homeless person. As far as when it went from being a man to animal, well, that is probably a societal thing. These days some people with a certain bent (guidelines prevent me from elaborating in public forum) consider only modern man as being worthy of being called "Man". All others are merely animals. The society of the 1800's and early 1900's were much less puritanical in may ways than the society we know today.
