Abstract: The cost of DNA sequencing continues to fall, which makes it feasible to develop genomic resources for new model species that are well suited for studying questions in evolutionary biology. The thousands of closely related cichlid fishes in the lakes of East Africa are an ideal model system for understanding the genetic basis of vertebrate speciation. Genomic techniques are helping to integrate empirical and theoretical studies by identifying the genes that underlie the phenotypic differences among species.

Island radiation on a continental scale: Exceptional rates of plant diversification after uplift of the Andes
Colin E. Hughes,Ruth J. Eastwood +1 more
TL;DR: Data from other genera indicate that lupines are one of a set of similarly rapid Andean plant radiations, continental in scale and island-like in stimulus, suggesting that the high-elevation Andean flora provides a system that rivals other groups, including cichlids, for understanding rapid species diversification.

TL;DR: This article found an excess of gene duplications in the East African lineage compared to Nile tilapia and other teleosts, an abundance of non-coding element divergence, accelerated coding sequence evolution, expression divergence associated with transposable element insertions, and regulation by novel microRNAs.
African cichlid fish: a model system in adaptive radiation research
TL;DR: The evidence suggests that speciation rate declines through time as niches get filled up during adaptive radiation, but the data suggest that the propensity to radiate within lakes is a derived property that evolved during the evolutionary history of some African cichlids, and does not coincide with the appearance of proposed key innovations in morphology and life history.

Genome evolution and biodiversity in teleost fish
TL;DR: Comparison of data generated by current and future genome projects as well as complementary studies in other species will allow one to approach the molecular and evolutionary mechanisms underlying genome diversity in fish, and will certainly significantly contribute to the understanding of gene evolution and function in humans and other vertebrates.
