Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …

A primary roadblock to our understanding of speciation is that it usually occurs over a
timeframe that is too long to study from start to finish. The idea of a speciation continuum …

Groundbreaking research on the universality and diversity of microorganisms is now
challenging the life sciences to upgrade fundamental theories that once seemed …

Speciation rates vary considerably among lineages, and our understanding of what drives
the rapid succession of speciation events within young adaptive radiations remains …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

Epistasis occurs when the effect of a mutation depends on its carrier's genetic background.
Despite increasing evidence that epistasis for fitness is common, its role during evolution is …

Gene flow is a fundamental evolutionary force in adaptation that is especially important to
understand as humans are rapidly changing both the natural environment and natural levels …

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

Hybridization among diverging lineages is common in nature. Genomic data provide a
special opportunity to characterize the history of hybridization and the genetic basis of …
