Dying Young Didn't Wipe Out Neanderthals

Dying young was not likely the reason Neanderthals went extinct, said a study out Monday that suggests early modern humans had about the same life expectancy as their hairier, ancient cousins.

Scientists have puzzled over why the Neanderthals disappeared just as modern humans were making huge gains and moving into new parts of Africa and Europe, and some have speculated that a difference in longevity may have been to blame.

If anything, higher fertility rates and lower infant mortality gave modern humans an advantage over the Neanderthals, who died off about 30,000 years ago, said the study in the Proceedings of the National Academy of Sciences.

Scientist Erik Trinkaus of Washington University studied fossil records to get an idea of the life span of Neanderthals and early modern humans, who co-existed in different parts of the world for about 150,000 years.

He found about the same number of 20- to 40-year-old adults in both populations, an indication that would reflect "similar patterns of adult mortality," said the study.
