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 …

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 …

Speciation is a continuous process during which genetic changes gradually accumulate in
the genomes of diverging species. Recent studies have documented highly heterogeneous …

Summary Publication of The Genetics of Colonizing Species in 1965 launched the field of
invasion genetics and highlighted the value of biological invasions as natural ecological and …

Understanding the distribution of crossovers along chromosomes is crucial to evolutionary
genomics because the crossover rate determines how strongly a genome region is …

Identifying genomic regions underlying adaptation in extant lineages is key to understanding
the trajectories along which biodiversity evolves. However, this task is complicated by …

The genetic basis of parallel evolution of similar species is of great interest in evolutionary
biology. In the adaptive radiation of Lake Victoria cichlid fishes, sister species with either …

The study of parallel ecological divergence provides important clues to the operation of
natural selection. Parallel divergence often occurs in heterogeneous environments with …

Parallel speciation occurs when selection drives repeated, independent adaptive
divergence that reduces gene flow between ecotypes. Classical examples show parallel …
