Studies on human telomeres have established that telomeres exert a significant influence on
lifespan and health of organisms. However, recent research has indicated that the original …

Social isolation negatively affects health, induces detrimental behaviors, and shortens
lifespan in social species. Little is known about the mechanisms underpinning these effects …

One of the central questions of ageing research is why lifespans of organisms differ so
tremendously among related taxa and, even more surprising, among members of the same …

Individual lifespans vary tremendously between and also within species, but the proximate
and ultimate causes of different ageing speeds are still not well understood. Sociality …

Longevity is traded off with fecundity in most solitary species, but the two traits are positively
linked in social insects. In ants, the most fecund individuals (queens and kings) live longer …

Three widely accepted assumptions are based on telomere research in human cells:(i)
telomere length is a determinant of replicative ageing;(ii) telomerase activity in somatic cells …

Female social insects represent a dramatic exception of the evolutionarily conserved
physiological trade-off between reproduction and life span, where aging is positively …

Eusocial insect queens are remarkable in their ability to maximize both fecundity and
longevity, thus escaping the typical trade-off between these two traits. Several mechanisms …

Simple Summary Immune mechanisms in insects include cellular and humoral defenses.
One of these cellular defense mechanisms is phagocytosis. The humoral defense …

Simple Summary Explanations for the evolution of menopause in humans and other animals
concern the indirect fitness benefits that older females can receive by caring for the offspring …
