Mitochondria were first postulated to contribute to aging more than 40 years ago. During the
following decades, multiple lines of evidence in model organisms and humans showed that …

Between the 1930s and 50s, evolutionary biologists developed a successful theory of why
organisms age, firmly rooted in population genetic principles. By the 1980s the evolution of …

Lifetime reproductive success of individuals in a natural population provides an estimate of
Darwinian fitness. We calculated lifetime reproductive success in a colony of female …

Empirical evidence for declines in fitness components (survival and reproductive
performance) with age has recently accumulated in wild populations, highlighting that the …

Despite tremendous progress in recent years, our understanding of the evolution of ageing
is still incomplete. A dominant paradigm maintains that ageing evolves due to the competing …

Research programmes on oxidative stress and hormesis are wide ranging. Biomedical and
toxicological sciences have traditionally centralised such research, but in the last years we …

Is senescence inevitable and universal for all living organisms, as evolutionary theories
predict? Although evidence generally supports this hypothesis, it has been proposed that …

Technological advances in recent years have seen an explosion of tracking and stable
isotope studies of seabirds, often involving repeated measures from the same individuals …

According to recent empirical studies, reproductive senescence, the decline in reproductive
success with increasing age, seems to be nearly ubiquitous in the wild. However, a clear …

Social interactions help group-living organisms cope with socio-environmental challenges
and are central to survival and reproductive success. Recent research has shown that social …
