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 …

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 …

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

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

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 …

Populations adapt to novel environments in two distinct ways: selection on pre-existing
genetic variation and selection on new mutations. These alternative sources of beneficial …

Ecological processes are central to the formation of new species when barriers to gene flow
(reproductive isolation) evolve between populations as a result of ecologically‐based …

Levels of genetic differentiation between populations can be highly variable across the
genome, with divergent selection contributing to such heterogeneous genomic divergence …
