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

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

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 …

Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Speciation, that is, the evolution of reproductive barriers eventually leading to complete
isolation, is a crucial process generating biodiversity. Recent work has contributed much to …

During the process of speciation, populations may diverge for traits and at their underlying
loci that contribute barriers to gene flow. These barrier traits and barrier loci underlie …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

How common is speciation‐with‐gene‐flow? How much does gene flow impact on
speciation? To answer questions like these requires understanding of the common …

Evolution in allopatric populations can lead to incompatibilities that result in reduced hybrid
fitness and ultimately reproductive isolation upon secondary contact. The D obzhansky–M …
