There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
Post #87 is telling a totally different theory of polar bear evolution; saying that perhaps 4 or 5 million years ago both the polar bear and the grizzly evolved from a common ancestor - as did the grizzly and the cave bear. Then Dr. Thea Bechshoft goes on to say that the split from the common ancestor happened at various intervals... ?
IMO... the other theory makes better sense. A group of brown bears migrated far to the north, were stranded, and the survivors evolved into polar bears. Exactly when is an ongoing debate.
