Tigers are less closely related to lions, leopards and jaguars than these other big cats are to each other, according to a new comprehensive study. The genetic analysis also reveals the tiger began evolving 3.2 million years ago, and its closest living relative is the equally endangered snow leopard. Despite the popularity and endangered status of tigers, much remains to be discovered about them, including how they evolved. It has long been known that the five species of big cat - the tiger, lion, leopard, jaguar and snow leopard, which belong to the Panthera genus - and the two species of clouded leopard are more closely related to each other than to other smaller cats. But it has been difficult to pin down the exact relationships between them. So to find out more, scientists Mr Brian Davis, Dr Gang Li and Professor William Murphy conducted an analysis of the DNA of all these species. Their data strongly suggests that lions, leopards and jaguars are most closely related to each other. Their ancestor split from other cats around 4.3 to 3.8 million years ago. About 3.6 to 2.5 million years ago, the jaguar began to evolve, while lions and leopards split from one other about 3.1 to 1.95 million years ago. But the tiger had already emerged by this point. The ancestor of tigers and snow leopards also branched off around 3.9 million years ago. The tiger then began to evolve into a unique species toward the end of the Pliocene epoch, about 3.2 mya. "
Is this really new? I feel like I've read this before right here on wildfact.
