Human, All Too Human - 4 - Lifespan

"A new study by a Washington University in St. Louis suggests life expectancy was probably the same for early modern and late archaic humans and did not factor in the extinction of Neanderthals. Our species, Homo sapiens, is the only surviving lineage of the genus Homo. Still, there once were many others, all of whom could also be called human. One puzzle was the lack of elderly individuals. It was therefore suggested that early hominins might have had a shorter life expectancy than early modern humans, with our lineage ultimately outnumbering Neanderthals, contributing to their demise." But  Neanderthals and early modern humans had same lifespan.
