"Webthat speciation with gene flow plays a larger role in marine systems compared to terres-trial ecosystems (Miglietta et al., 2011; Bowen et al., 2013). Here, we review potential cases of speciation with gene flow in marine sys-tems. We discuss and compare the potential mechanisms driving divergence with gene flow among different case studies.

WebAbstract.-Evolutionary biologists assume that species formation requires a drastic reduction in gene exchange between populations, but the rate sufficient to prevent speciation is unknown. To study speciation, we use a new class of population genetic models that incorporate simple developmental genetic rules, likely present in all organisms, to WebGenetic divergence will always accompany reproductive isolation, either due to novel adaptations via selection and/or due to genetic drift, and is the principal mechanism underlying speciation. On a molecular genetics level, genetic divergence is due to changes in a small number of genes in a species, resulting in speciation.
