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.

The P. atrox point is probably right according to Sotnikova and Foronova (2014) paper.

For the questions, I think we need to remember that the two P. spelaea specimens/subspecies tested by Barnett et al. (2016) have their most recent common ancestor split only 500 kya. It is the cave lion "stem" group that split 1.89 mya, which is not genetically identical to the most recent form of P. spelaea as the phylogenetic tree shows. This keeps open the possbility of the following evolution:
Cave lion stem group (1.89 mya) -> P. (spelaea?) fossilis (1 mya) -> P. spelaea spelaea 500 kya

So there must be a stem group somewhere out there in the connection between Africa and Eurasia that dates to about 2 mya.
