DNA traces evolution of extinct sabertooths and the American cheetah-like cat

ic data indicate that this similarity is in fact a marvellous example of evolutionary parallelism, the development of similar body plans in response to similar ecological pressures. In light of the new DNA data and fossil information from other studies, it appears likely that a puma-like ancestor that migrated to the New World may have given rise to Miracinonyx and ancestral Puma a few million years ago, around the time that the North American prairie is thought to have undergone expansion.
