P30 Researchers Discover Earliest Recorded Lead Exposure in Neanderthal Teeth

Using evidence found in teeth from two Neanderthals from southeastern France, researchers from the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai report the earliest evidence of lead exposure in an extinct human-like species from 250,000 years ago. This study is the first to report lead exposure in Neanderthal and is the first to use teeth to reconstruct climate during and timing of key developmental events including weaning and nursing duration— key determinants of population growth. Results of the study were published in Science Advances, a journal published by the American Association for the Advancement of Science. To read more click here.
