American cats   posted by Razib @ 8/08/2005 06:17:00 PM

DNA traces evolution of extinct sabertooths and the American cheetah-like cat. Basically, the famous saber-toothed cat (Smilodon) has a distant relationship to the rest of the felines, while the "American cheetah" is actually a case of convergent evolution to the Old World cheetah, as it seems to have been derived from an ancient proto-puma.
