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

Explanations for taxonomic diversity in a particular clade often implicate evolutionary
innovations, possessed by members of the clade, that are thought to have favoured …

The process of adaptive radiation—the proliferation of species from a single ancestor and
diversification into many ecologically different forms—has been of great interest to …

Since 1990 the recognition of deep homologies among metazoan developmental processes
and the spread of more mechanistic approaches to developmental biology have led to a …

Phenotypic plasticity (the ability of a single genotype to produce multiple phenotypes in
response to variation in the environment) is commonplace. Yet its evolutionary significance …

Uncovering the principles governing the origin and fate of biodiversity is the central goal of
modern biology. The first edition (2014) of this novel textbook drew on more than two …

The origin or evolutionarysuccess' of taxa is often attributed to key innovations—aspects of
organismal phenotype that promote diversification. Different ways of delimiting taxa and …

Evolutionary innovation contributes to the spectacular diversity of species and phenotypes
across the tree of life.'Key innovations' are widely operationalized within evolutionary …

Ecology Letters (2011) 14: 841–851 Abstract Ecological specialisation concerns all species
