Negligible senescence species resist aging by maintaining proliferative capacity, not by preventing damage

Some animals—lobsters, hydra, certain jellyfish—show no signs of aging. They grow, reproduce, and repair indefinitely. How?

The answer is not that they avoid damage. They accumulate mutations, oxidative stress, and cellular dysfunction like any organism. The difference is that they maintain unlimited regenerative capacity through continuous stem cell activity.

The hypothesis: negligible senescence works not by preventing aging-related damage, but by out-repairing it through sustained proliferative capacity.
