Different species of cats mated with each other at several points in history, a new genetic study of felines reveals.

These ancient cat hybrids may have shaped the course of feline evolution.

Phylogenomic evidence for ancient hybridization...

Interspecies hybridization has been recently recognized as potentially common in wild animals, but the extent to which it shapes modern genomes is still poorly understood.

He is neither a lion nor a tiger, but he is about the size of both of them combined.

Hybrid Vigor

The tendency of hybrid offspring to exhibit characteristics that are superior to either of the parents is known as Heterosis or Hybrid Vigor. This is what occurs in ligers. Ligers are bigger than both their parents - lions and tigers. Like another much more common hybrid species, mules, which are bigger than both of their parents - horses and donkeys.

Human origins: Are we hybrids?

Human origins may be traceable to a hybrid cross, an explanation that accounts for a large amount of physiological and anatomical data.

Grolar Bears and Narwulga Whales

Published: February 24, 2011

In 2006, Arctic hunters shot and killed a strange-looking, white bear. It was strange because the bear had large patches of brown fur in its coat. Subsequent genetic analysis showed that it was in fact a cross between a polar bear and a grizzly bear (making it a "grolar" or "pizzly" bear).

Hybrids May Thrive Where Parents Fear to Tread
New York Times - Sean B. Carroll
Published: September 13, 2010

While several examples of human-bred animal hybrids are well known and can thrive in captivity including zorses (zebra-horse), beefalo (bison-beef cattle) and, of course, mules (donkey-horse), naturally occurring animal hybrids have many factors working against their longer-term success.

The Prevalence of Animal Hybrids
Eugene M. McCarthy, Ph.D.
Published: March 22, 2009

It is widely supposed that animal hybrids are less common, or are more sterile than hybrids produced by plants. For this reason, hybridization has been deemed less important in the evolution of animals than in that of plants.
