Speciation with gene flow is greatly facilitated when traits subject to divergent selection also
contribute to non-random mating. Such traits have been called 'magic traits', which could be …

Sexual selection plays several intricate and complex roles in the related processes of local
adaptation and speciation. In some cases sexual selection can promote these processes …

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 …

The extent to which interspecific interference competition has contributed to character
evolution is one of the most neglected problems in evolutionary biology. When formerly …

Dramatic pigmentation changes have evolved within most vertebrate groups, including fish
and humans. Here we use genetic crosses in sticklebacks to investigate the parallel origin of …

Speciation can be viewed as a continuum, potentially divisible into several states:(1)
continuous variation within panmictic populations,(2) partially discontinuous variation with …

Adaptive diversification is driven by selection in ecologically different environments. In
absence of geographical barriers to dispersal, this adaptive divergence (AD) may be …

Population genomic studies are beginning to provide a more comprehensive view of
dynamic genome-scale processes in evolution. Patterns of genomic architecture, such as …

Although theory indicates that natural selection can facilitate speciation as a by-product,
demonstrating ongoing speciation via this by-product mechanism in nature has proven …
