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.
P. shawi is so poorly defined due to the records being teeth and a broken humerus that in most cases, one can get away with calling any old African pantherine from that time period P. shawi. Would you remember where that was read? I may have missed it or forgotten.
In terms of population movement, usually it's a portion of a population that migrates and not the entirety. So the northern form of P. shawi (or whatever we'd like to call the stem group) that stayed in Africa could have been the parent of modern lions as well.
