An ancient human ancestor known as nutcracker man may have preferred to munch on grass.
Named such due to its large teeth scientists believe the prehistoric hominid might have grazed on the same fields as the ancestors of modern pigs and zebras. "It most likely was eating grass, and most definitely was not cracking nuts," says geochemist Thure Cerling.
Researchers used a drill to pulverize tooth enamel, taken from already broken tooth samples from 22 individuals who lived in that period, and examined carbon isotope ratios that revealed what kind of food they were eating.
