Unformatted text preview: who lived between two million and 500,000 years ago. The third group was the European
Neandertals from 130,000 to 30,000 years ago. And the last
consisted of modern Europeans from the early Upper Paleolith- ic period, who lived between about 30,000 and 20,000 years
ago and left behind sophisticated cultural remains.
Although we expected to find increases in longevity over
time, we were unprepared for how striking our results would
turn out to be. We observed a small trend of increased longevity over time among all samples, but the difference between earlier humans and the modern humans of the Upper Paleolithic
was a dramatic fivefold increase in the OY ratio. Thus, for every
10 young adult Neandertals who died between the ages of 15
and 30, there were only four older adults who survived past age
30; in contrast, for every 10 young adults in the European Upper Paleolithic death distribution, there were 20 potential
grandparents. Wondering whether the higher numbers of burials at Upper Paleolithic sites might account for the high number of older adults in that sample, we reanalyzed our Upper Paleolithic sample...
