Modularity is now generally recognized as a fundamental feature of organisms, one that may
have profound consequences for evolution. Modularity has recently become a major focus of …

Understanding how genotypes map onto phenotypes, fitness, and eventually organisms is
arguably the next major missing piece in a fully predictive theory of evolution. We refer to this …

Classic debates concerning the extent to which scientists can predict evolution have gained
new urgency as environmental changes force species to adapt or risk extinction. We …

A fuller understanding of the role of developmental bias in shaping large‐scale evolutionary
patterns requires integrating bias (the probability distribution of variation accessible to an …

Deciphering the genotype–phenotype map necessitates relating variation at the genetic
level to variation at the phenotypic level. This endeavour is inherently limited by the …

Evolutionary biology is paying increasing attention to the mechanisms that enable
phenotypic plasticity, evolvability, and extra‐genetic inheritance. Yet, there is a concern that …

Environments change, for both natural and anthropogenic reasons, which can threaten
species persistence. Evolutionary adaptation is a potentially powerful mechanism to allow …

Domestic animals are ubiquitous. In contrast to the biodiversity crisis currently impacting
many kinds of animals and plants, not a single domesticated species is endangered …

Quantitative genetic theory proposes that phenotypic evolution is shaped by G, the matrix of
genetic variances and covariances among traits. In species with separate sexes, the …

The G matrix is a statistical summary of the genetic basis of a set of traits and a central pillar
of quantitative genetics. A persistent controversy is whether G changes slowly or quickly …
