- Comparative analyses of aging-related genes in long-lived . . .
Extant mammals differ dramatically in their maximum lifespans, ranging from a little over 1 year (e g , forest shrews, Myosorex varius) to more than 200 years (e g , bowhead whales, Balaena mysticetus), a difference of more than 100-fold 1 In general, larger species tend to live longer than smaller ones, presumably due to higher intrinsic fitness (i e , stress resistance) and a lack of apex
