Life expectancy was probably the same for early modern and late archaichumans and did not factor in the extinction of Neanderthals, suggests a new study by a Washington University in St. Louis anthropologist.
Erik Trinkaus, PhD, Professor of Anthropology in Arts & Sciences, examined the fossil record to assess adult mortality for both groups, which co-existed in different regions for roughly 150,000 years. Trinkaus found that the proportions of 20 to 40-year-old adults versus adults older than 40, were about the same for early modern humans and Neandertals.
