In human populations, women consistently outlive men, which suggests profound biological foundations for sex differences in survival.

What about other mammals in the wild?

Quantifying whether such sex difference is also pervasive in wild mammals is a vital challenge in both evolutionary biology and biogerontology.

Elephant seals are one of the species in which females outlive males. © Isabelle CHARRIER / Neuro-PSI / CNRS Photothèquenoted, “Our analyses suggest that the magnitude of sex differences in mammalian mortality patterns is likely shaped by local environmental conditions in interaction with the sex-specific costs of sexual selection.”
