Flexi Says: The fossil record for the modern tiger species (Panthera tigris) goes back about 2.5 million years. The most recent ice age occurred during the Pleistocene, which began about 2.6 million years ago and ended about 11,700 years ago. Therefore, modern tigers lived through the ice ages. Note that modern tigers are different from the popularly known ice age mammals called saber-toothed tigers or saber-toothed cats, which are not close relatives of tigers or cats.
