Abstract In 1983, Russell Lande and Stevan Arnold published “The measurement of
selection on correlated characters,” which became a highly influential citation classic in …

Developmental plasticity is an important product of evolutionary processes, allowing
organisms to maintain high fitness in the face of environmental perturbations. Once evolved …

The theory of evolution by natural selection is, perhaps, the crowning intellectual
achievement of the biological sciences. There is considerable debate, though, about which …

Indirect genetic effects (IGEs) exist when there is heritable variation in one organism's ability
to alter a second organism's traits. For example, parasites have antigens that can induce a …

What limits the size of nature's most extreme structures? For weapons like beetle horns, one
possibility is a tradeoff associated with mechanical levers: as the output arm of the lever …

The vertebrate immune system provides an impressively effective defense against parasites
and pathogens. However, these benefits must be balanced against a range of costly side …

A central tenet of niche construction (NC) theory is that organisms can alter their
environments in heritable and evolutionarily important ways, often altering selection …

Social evolution and the dynamics of social interactions have previously been studied under
the frameworks of quantitative genetics and behavioural ecology. In quantitative genetics …

Collective phenotypes, which arise from the interactions among individuals, can be
important for the evolution of higher levels of biological organization. However, how a …

Mutualisms, reciprocally beneficial interactions between two or more species, are ubiquitous
in nature. A common feature of mutualisms is extensive context‐dependent variation in …
