Then why aren't they still around? Why don't they evolve again?

  Saber tooth tigers and humans coexisted for a while, and the tigers were probably very dangerous to us. That and having to adapt to the end of the ice age, I don't think we know what was the bigger factor.

  The large teeth may have been useful to hit vital organs on large prey that used to be common but now extinct. No large prey - no sabre teeth needed.

  Probably climate change and humans.

  They may wekk evolve again, given the right circumstances. Giganticism in both predator and prey is a response to plentiful food. It happened with both dinosaurs and mammals. By the same token, animals respond by evolving into smaller forms in food sparse environments. On the Indonesian island of Flores, both hominids and elephants became tiny.
