Where The Camels Roamed

University of Colorado scientists have found protein residue from the North American camel on stone tools (inset) from the Clovis era about 13,000 years ago. The sharp instruments were apparently used for butchering; the camels became extinct on the continent some 11,000 years ago (possibly because of overhunting). Traces of bear, horse and sheep proteins were also detected on stone tools at the northern Colorado cache, unearthed during a home-landscaping project.
