Life expectancy was probably the same for early modern and late archaic
humans 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.
This similar age distribution, says Trinkaus, reflects similar patterns of adult mortality and treatment of the elderly in the context of highly mobile hunting-and-gathering human populations.
