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.
It is now crystal clear that Panthera atrox was definitely born from Panthera fossilis, but Panthera spelaea was not the offspring of Panthera fossilis.
I am just more curious about the origin of Panthera spelaea, if not from Panthera fossilis, where they evolved from?
