BOLOGNA, ITALY—Cosmos Magazine reports that an international team of scientists led by Marco Candela of the University of Bologna analyzed 50,000-year-old Neanderthal fecal matter uncovered in El Salt, an archaeological site in Spain, and found it contained microorganisms similar to those still found in the modern human gut. “This finding allows us to state that these ancient microorganisms populated the intestine of our species before the separation between Sapiens and Neanderthals, which occurred about 700,000 years ago,” said team member Silvia Turroni of the University of Bologna. Microorganisms in the gut are thought to help regulate metabolism and the immune system. The study could therefore help scientists understand which species in the microbiota have been essential to human health and developed a diet supportive of microbiota diversity, Candela explained.
