Cryptic genetic variation (CGV) is invisible under normal conditions, but it can fuel evolution
when circumstances change. In theory, CGV can represent a massive cache of adaptive …

The evolutionary theory of ageing explains why ageing occurs, giving valuable insight into
the mechanisms underlying the complex cellular and molecular changes that contribute to …

Over the past decade, advances in both molecular developmental biology and evolutionary
ecology have made possible a new understanding of organisms as dynamic systems …

The past decade has seen a profound change in the scientific understanding of
reproduction. The traditional view of reproduction as a joint venture undertaken by two …

Although adaptation of Drosophila to thermal extremes has been investigated for many
years, only recently has much progress been made in identifying the genetic and …

Sexual conflict occurs when the genetic interests of males and females diverge. Recent
evidence supporting the view that male and female genomes are in conflict has now …

▪ Abstract Phenotypic variation for quantitative traits results from the segregation of alleles at
multiple quantitative trait loci (QTL) with effects that are sensitive to the genetic, sexual, and …

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Developmental plasticity refers to the property by which the same genotype produces
distinct phenotypes depending on the environmental conditions under which development …

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 …
