Converging lines of inquiry from across the social and biological sciences target the adult
sex ratio (ASR; the proportion of males in the adult population) as a fundamental population …

Sex differences in aging occur in many animal species, and they include sex differences in
lifespan, in the onset and progression of age‐associated decline, and in physiological and …

In human populations, women consistently outlive men, which suggests profound biological
foundations for sex differences in survival. Quantifying whether such sex differences are also …

While it is commonly believed that animals live longer in zoos than in the wild, this
assumption has rarely been tested. We compared four survival metrics (longevity, baseline …

It is well known that women live longer than men. This gap is observed in most human
populations and can even reach 10–15 years. In addition, most of the known super …

Williams' evolutionary theory of senescence based on antagonistic pleiotropy has become a
landmark in evolutionary biology, and more recently in biogerontology and evolutionary …

In mammals, females generally live longer than males. Nevertheless, the mechanisms
underpinning sex-dependent longevity are currently unclear. Epigenetic clocks are powerful …

The Ape that Understood the Universe is the story of the strangest animal in the world: the
human animal. It opens with a question: How would an alien scientist view our species …

Senescence patterns are highly variable across the animal kingdom. However, while
empirical evidence of actuarial senescence in vertebrates is accumulating in the wild and …

Males and females in many species differ in how they age and how long they live. These
differences have motivated much research, concerning both their evolution and the …
