A 97-generation experiment just challenged what scientists thought they knew about exercise and aging — raising the question of whether the old theory ever held up.

Theory Briefing
- A 97-generation experiment — an unusually long-running study — produced results that undercut a widely accepted theory linking exercise to aging.
- The findings suggest the relationship between physical activity and how organisms age may be more complicated than the prevailing model assumed.
- Running the experiment across 97 generations means the effects observed are deeply embedded, not a short-term or incidental result.
