All humans age, but how we age—and how fast—differs considerably from person to
person. This deviation between apparent age and chronological age is often referred to as …

Reproduction, a basic property of biological life, entails costs for an organism, ultimately
detectable as reduction in survival prospects. Telomeres are an excellent candidate …

Aging is classically conceptualized as an ever-increasing trajectory of damage accumulation
and loss of function, leading to increases in morbidity and mortality. However, recent in vitro …

A central prediction of evolutionary theory is that energy invested into reproduction comes at
the expense of somatic maintenance and repair, accelerating biological aging. Supporting …

Aging is the single most important risk factor for diseases that are currently the leading
causes of morbidity and mortality. However, there is considerable inter-individual variability …

Evolutionary theories of ageing point to reproduction as a significant factor to consider when
asking why ageing occurs and why there is inter-individual variation in its progression …

Economic models predominate in life history research, which investigates the allocation of
an organism's resources to growth, reproduction, and maintenance. These approaches …

The mechanisms that contribute to variation in lifetime reproductive success are not well
understood. One possibility is that telomeres, conserved DNA sequences at chromosome …

Prenatal maternal stress has a negative impact on child health but the mechanisms through
which maternal stress affects child health are unclear. Epigenetic variation, such as DNA …

Telomeres are protective caps at the end of chromosomes, and their length is positively
correlated with individual health and lifespan across taxa. Longitudinal studies have …
