There is increasing evidence that phenotypic plasticity can promote population divergence
by facilitating phenotypic diversification and, eventually, genetic divergence. When a …

Parallel phenotypic diversification in closely related species is a rigorous framework for
testing the role of natural selection in evolution. Do parallel phenotypes always diversify by …

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Domestication involves recent adaptation under strong human selection and rapid
diversification and therefore constitutes a good model for studies of these processes. We …

Fundamental to understanding how biodiversity arises and adapts is whether evolution is
predictable in the face of stochastic genetic and demographic factors. Here we show rapid …

One of the most celebrated examples of sympatric speciation in nature are monophyletic
radiations of cichlid fishes endemic to Cameroon crater lakes. However, phylogenetic …

The genomics era has opened up exciting possibilities in the field of conservation biology by
enabling genomic analyses of threatened species that previously were limited to model …

Background Phenotypic evolution and its role in the diversification of organisms is a central
topic in evolutionary biology. A neglected factor during the modern evolutionary synthesis …

The view of species as entities subjected to natural selection and amenable to change put
forth by Charles Darwin and Alfred Wallace laid the conceptual foundation for understanding …

Sympatric speciation has been of key interest to biologists investigating how natural and
sexual selection drive speciation without the confounding variable of geographic isolation …
