Researchers have uncovered evidence of food and potential respiratory irritants entrapped in the dental tartar of 400,000-year-old teeth at Qesem Cave near Tel Aviv, the site of many major discoveries from the late Lower Paleolithic period. The research provides direct evidence of what early Palaeolithic people ate and the quality of the air they breathed inside Qesem Cave.
