As is true of virtually every realm of the biological sciences, our understanding of speciation
is increasingly informed by the genomic revolution of the past decade. Investigators can ask …

Sympatric speciation has been of key interest to biologists investigating how natural and
sexual selection drive speciation without the confounding variable of geographic isolation …

Restriction site-associated DNA sequencing (RAD-seq) allows for the genome-wide
discovery and genoty** of single-nucleotide polymorphisms in hundreds of individuals at …

The transition from 'well-marked varieties' of a single species into 'well-defined species'—
especially in the absence of geographic barriers to gene flow (sympatric speciation)—has …

Parallel and convergent evolution offer some of the most compelling evidence for the
significance of natural selection in evolution, as the emergence of similar adaptive solutions …

Different horticultural types of lettuce exhibit tremendous morphological variation. However,
the molecular basis for domestication and divergence among the different horticultural types …

Understanding the extent to which ecological divergence is repeatable is essential for
predicting responses of biodiversity to environmental change. Here we test the predictability …

Rapid diversification often involves complex histories of gene flow that leave variable and
conflicting signatures of evolutionary relatedness across the genome. Identifying the extent …

Parallel divergence across replicated species pairs occurring in similar environmental
contrasts may arise through distinct evolutionary scenarios. Deciphering whether such …

Sympatric speciation illustrates how natural and sexual selection may create new species in
isolation without geographic barriers. However, recent genomic reanalyses of classic …
