A 31,000-year-old fossil has challenged everything scientists thought about the extinct 'American cheetah' — its DNA and diet tell a surprising story

Ancient DNA studies have rewritten the family tree of the "American cheetah," Miracinonyx trumani. Genetic evidence shows this extinct cat was closely related to modern pumas. Fossil analysis suggests a surprisingly varied diet, including aquatic prey. This indicates a remarkable adaptability to different environments across North America. The findings challenge the long-held perception of this predator as a specialized speed hunter.
