DNA extracted from the teeth of ancient saber-toothed cats shows they were cousins of modern cats but not direct ancestors, scientists say. And they also rejected a theory that cheetahs originally evolved from a similar-looking North American ancestor. 09
What are saber-toothed tigers related to?
Saber-toothed cat, also called saber-toothed tiger or saber-toothed lion, one of the extinct feline carnivores belonging to the extinct family Nimravidae or subfamily Machairodontinae of the cat family (Felidae).
What is the closest relative of the saber-toothed tiger?
According to the BBC, saber-toothed cats went extinct around 10,000 years ago, and it’s suggested that their closest living relative may not be the tiger or lion, but the clouded leopard.
What did the saber-tooth tiger evolve from?
The New World genus Smilodon is thought to have evolved from the dagger-toothed cats of the Old World genus Megantereon, which may have spread into the Americas during the Pliocene (Blancan) epoch. Two Late Pleistocene (Rancholabrean) species of Smilodon are recognized, with S.
Are saber-toothed tigers related to jaguars?
fatalis is the last of the three species to go extinct – meaning humans may have ridden the last of the Smilodons. Smilodon is a genus of the subfamily Machairodontinae of the family Felidae, so they are true cats. Although they are true cats, they were not the ancestors of cheetahs or jaguars.
What are saber-toothed tigers related to?
Sabertooth evolved both among true cats, or the family Felidae (these saber-toothed cats are sometimes classified in a separate subfamily of cats, the Machairodontinae), and within the Nimravidae (a family of extinct carnivores associated with true cats as well as civets and mongooses was related). .

Did tigers evolve from saber-toothed cats?
The saber-toothed cat is not closely related to today’s tiger. In fact, he is not closely related to any of the modern cats. The saber-toothed cat was an evolutionary branch that died out earlier, while today’s modern cats are an entirely different evolutionary branch that appeared much later.
What animal evolved from the saber-toothed tiger?

When did the saber-toothed tiger evolve?
Saber-toothed cats existed from the Eocene to the Pleistocene (56 million to 11,700 years ago). According to the fossil record, the Nimravidae existed around 37 million to 7 million years ago.
How did the saber tooth evolve?
The evolution of enlarged canines in Tertiary carnivores was a result of large mammals being the source of prey for saber-toothed cats. The evolution of saber-tooth disease appears to represent a change in function and killing behavior rather than a change in predator-prey relationships.
