Speciation is often thought of as a slow process due to the waiting times for mutations that
cause incompatibilities, and permit ecological differentiation or assortative mating. Cases of …

Global environmental changes strongly impact wild and domesticated species biology and
their associated ecosystem services. For crops, global warming has led to significant …

Hybridisation and introgression can dramatically alter the relationships among groups of
species, leading to phylogenetic discordance across the genome and between populations …

Supergenes are groups of tightly linked loci whose variation is inherited as a single
Mendelian locus and are a common genetic architecture for complex traits under balancing …

Studies in a variety of species have shown evidence for positively selected variants
introduced into a population via introgression from another, distantly related population—a …

Adaptive radiations are prominent components of the world's biodiversity. They comprise
many species derived from one or a small number of ancestral species in a geologically …

Evolutionary variation in the wing pigmentation of butterflies and moths offers striking
examples of adaptation by crypsis and mimicry. The cortex locus has been independently …

Sympatric speciation illustrates how natural and sexual selection may create new species in
isolation without geographic barriers. However, recent genomic reanalyses of classic …

Natural selection leaves distinct signatures in the genome that can reveal the targets and
history of adaptive evolution. By analysing high-coverage genome sequence data from 4 …

How frequent is gene flow between species? The pattern of evolution is typically portrayed
as a phylogenetic tree, yet gene flow between good species may be an important …
