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

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

Species can be defined as populations that are diagnosably distinct, reproductively isolated,
cohesive, or exclusive groups of organisms. Boundaries between species in sympatry are …

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 …

Divergent natural selection has been shown to promote speciation in many taxa. However,
although divergent selection often initiates the process of speciation, it often fails to complete …

Species are generally viewed by evolutionists as 'real'distinct entities in nature, making
speciation appear difficult. Charles Darwin had originally promoted a very different …

The role of natural selection in speciation, first described by Darwin, has finally been widely
accepted. Yet, the nature and time course of the genetic changes that result in speciation …

The likelihood of speciation in the face of homogenizing gene flow (ie without complete
geographical isolation) is one of the most debated topics in evolutionary biology …

Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

Genetic differentiation can be highly variable across the genome. For example, loci under
divergent selection and those tightly linked to them may exhibit elevated differentiation …
