The ancestors of tigers, along with those of jaguars, leopards, lions, snow leopards and clouded leopards, split off from the other ancestral cat lineages early in the evolution of the cat family and today form what is known as the Panthera lineage.igers (Panthera tigris) are the largest and most powerful of all cats. They are extremely agile despite their bulk and can leap between 8 and 10 meters in a single bound. They are also among the most recognizable of cats thanks to their distinct orange coat, black stripes and white markings.
