Evolvability is the ability of a biological system to produce phenotypic variation that is both
heritable and adaptive. It has long been the subject of anecdotal observations and …

The concept of evolvability emerged in the early 1990s and soon became fashionable as a
label for different streams of research in evolutionary biology. In evolutionary quantitative …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

A critical aspect of evolution is the layer of developmental physiology that operates between
the genotype and the anatomical phenotype. While much work has addressed the evolution …

What counts? In work, as in other areas of life, it is not always clear what standards we are
being judged by or how our worth is being determined. This can be disorienting and …

The first edition of Geometric Morphometrics for Biologists has been the primary resource for
teaching modern geometric methods of shape analysis to biologists who have a stronger …

It was first noticed 100 years ago that mutations tend to affect more than one phenotypic
characteristic, a phenomenon that was called'pleiotropy'. Because pleiotropy was found so …

The idea of 'key innovations' has long been influential in theoretical and empirical
approaches to understanding adaptive diversification. Despite originally revolving around …

A network of interactions is called modular if it is subdivided into relatively autonomous,
internally highly connected components. Modularity has emerged as a rallying point for …

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 …
