The emerging field of speciation genomics is advancing our understanding of the evolution
of reproductive isolation from the individual gene to a whole-genome perspective. In this …

▪ Abstract Many uses of gene trees implicitly assume that nominal species are monophyletic
in their alleles at the study locus. However, in well-sampled gene trees, certain alleles in one …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

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 …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

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 …

The ecological hypothesis of speciation is that reproductive isolation evolves ultimately as a
consequence of divergent natural selection on traits between environments. Ecological …

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

Hosts and their symbionts are involved in intimate physiological and ecological interactions.
The impact of these interactions on the evolution of each partner depends on the time‐scale …

Approximately 20 years ago, Avise and colleagues proposed the integration of
phylogenetics and population genetics for investigating the connection between micro-and …
