PLOS ONE, AINARA SISTIAGAFossilized feces offer new evidence that Neanderthals ate both meat and plants. Chemical analysis confirmed the oldest-known ancient human fecal matter, according to a study published yesterday (June 25) in PLOS ONE.
Previous isotope studies of bones suggested Neanderthals were primarily meat-eaters. Analyses of tartar from their teeth have indicated they may have also eaten plants, although some researchers noted that these plant remains could be traces from the stomach contents of herbivore prey.
Stool, however, is "the perfect evidence because you’re sure it was consumed," study author Ainara Sistiaga from the University of La Laguna in Spain told BBC News.
Sistiaga and her colleagues identified fecal biomarkers of cholesterol and plant sterol digestion in 50,000-year-old samples collected from Paleolithic sites in Spain. Future studies will help clarify the nature and proportion of plants in Neanderthal diets, and could reveal whether veggies were a dietary staple or eaten rarely. Such data also have implications in understanding how ...
