Kin Selection

The article considers kin selection but treats it as insufficient for the main mechanism. Aging advantage did not require direct parent-offspring competition in the model. Frequent parent-offspring competition did not strengthen the aging advantage in the reported runs. The mutation-only simulation results did not support kin selection as the explanation for aging-species success. A resource-freeing explanation for senescence risks circular reasoning if aging itself is what must be explained. The paper frames aging's advantage as faster adaptation rather than kin altruism.
