Abstract: Whether it's the latest band or the newest fashion fad, young people are usually the ones on the cutting edge. But a new study suggests that old people helped foster early human ingenuity. Populations from tens of thousands of years ago had a higher proportion of old individuals than did previous populations, researchers surmise based on tooth wear. Because these ancestors created more sophisticated tools and art than did their predecessors, the rise of modern culture might have required a mature population.
