DNA and Protein Studies Shake Up Sloth Family Tree

Sloths once roamed the Americas, ranging from cat-sized animals that lived in trees all the way up to giant ground sloths. The only species we know today, however, are the two- and three-fingered sloths. They seem remarkably similar, but new molecular (DNA and protein) studies estimate they last shared a …
