Why do the two sexes have different lifespans and rates of aging? Two hypotheses based
on asymmetric inheritance of sex chromosomes (“unguarded X”) or mitochondrial genomes …

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 …

1. Classic evolutionary models interpret ageing as a cost of reproduction, but evolutionary
research has thus far largely neglected the conceptual links between the evolution of ageing …

August Weismann proposed that genetic changes in somatic cells cannot pass to germ cells
and hence to next generations. Nevertheless, evidence is accumulating that some …

The trade-off between survival and reproduction is fundamental to life history theory. Sexual
selection is expected to favour a 'live fast die young'life history pattern in males due to …

Sexual ornaments are predicted to honestly signal individual condition. We might therefore
expect ornament expression to show a senescent decline, in parallel with late‐life …

Sexual interactions are often rife with conflict. Conflict between members of the same sex
over opportunities to mate has long been understood to effect evolution via sexual selection …

Although males and females share much of the same genome, selection is often distinct in
the two sexes. Sexually antagonistic loci will in theory cause a gender load in populations …

Evolutionary theories of aging predict that fitness‐related traits, including reproductive
performance, will senesce because the strength of selection declines with age. Sexual …

Background Interlocus conflict predicts (a) evolution of traits, beneficial to males but
detrimental to females and (b) evolution of aging and life-span under the influence of the …
