Genes determine species longevity, though within a species, and particularly within our species, the estimated involvement of genetic variants in individual life expectancy is becoming ever smaller as ever more data accumulates. Nonetheless, researchers are very interested in the comparative biology of aging, the question of why long-lived species are long-lived in comparison to their closest relatives. Which of the many evolved differences tend to produce a longer life span?
A longer species life span necessarily requires a lower incidence of cancer. Cancer is a numbers game: a larger body size means that there are more cells that can suffer mutation and become cancerous; a longer life allows more time for those cells to suffe…
