Abstract: Numerous genetic alterations can profoundly extend the life-span of model organisms. But some researchers question whether the life-stretching effect is just a peculiarity of the lab and whether the same mutations influence survival in a natural environment. Scientists are beginning to test how long-lived animals fare in natural settings and whether life-extending mutations have a fighting chance in nature. The results suggest that the advantage depends on environment and other genes, and they could help guide the design of therapies for humans.
