Cave lion cub

With a long period of genetic isolation, the isolated group would eventually mutate into another species.

Keep in mind that the Cave lion had been isolated from the African lion for almost 2 million years without any genetic exchange. In comparison, the Asiatic lion and Barbary lion had only been isolated from the African lion for 100,000 years. Meanwhile, the Asiatic lion and Barbary lion were straightly evolved from the African lion without any genetic barrier. The Cave lion only shared a common ancestor with the African lion back in 2 million years ago, but they didn't evolve from the African lion, nor vice versa.

They are just another brand of lion that cannot be considered as a subspecies of the African lion. You can consider both Asiatic lion and Barbary lion as a subspecies of the African lion, but not with the Cave lion.

As for the canine, tiger canine seems to overwhelmingly dominate in the absolute length and thickness with those extreme examples, so I am not sure how it would be considered weaker to withstand more pressure. Reply
