Prehistoric Food Source Discovered

Archaeologist Raven Garvey's study on digesta found in the stomachs of herbivores suggests that bison digesta may have played an important role in the diets of hunter-gatherers, providing enough proteins and carbohydrates to meet the USDA's nutritional recommendations for three days without eating any other food. Failure to account for this underappreciated resource could have important consequences in studies that address major questions in evolutionary anthropology.
