TL;DR: Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.

TL;DR: It is demonstrated that hybridization between two divergent lineages facilitated this process by providing genetic variation that subsequently became recombined and sorted into many new species, indicating rapid and extensive adaptive radiation.

TL;DR: Why old variants are particularly good fuel for rapid speciation, and hypothesize that variation in access to such old variants might contribute to the large variation in speciation rates observed in nature.

TL;DR: It is suggested that adaptive genomic differentiation at many genetic loci can arise and persist in sympatry at the very early stage of ecotype divergence, and that the genomic architecture of adaptation may facilitate this.

TL;DR: By reconstructing a large phylogeny of all currently described cichlid species, it is shown that explosive speciation is solely concentrated in species flocks of several large young lakes and suggested that the combination of ecological opportunity, sexual selection and exceptional genomic potential is the key to understanding explosive adaptive radiation.
