Genomics and the origin of species

Speciation is a fundamental evolutionary process, the knowledge of which is crucial
for understanding the origins of biodiversity. Genomic approaches are an increasingly
important aspect of this research field. We review current understanding of genome-wide
effects of accumulating reproductive isolation and of genomic properties that influence the
process of speciation. Building on this work, we identify emergent trends and gaps in our
understanding, propose new approaches to more fully integrate genomics into speciation.
