TL;DR: This work identifies the ecological and molecular basis of divergent evolution in the cichlid visual system, demonstrates associated divergence in male colouration and female preferences, and shows subsequent differentiation at neutral loci, indicating reproductive isolation.

TL;DR: Parallel evolution in two cichlid genera under strong divergent selection in a gene that affects both is demonstrated, showing that the reciprocal fixation adapts populations to divergent light environments.

TL;DR: It is reported that a male colour trait, which has previously been shown to be important for behavioural reproductive isolation between this species and a close relative, is under directional sexual selection by female mate choice within this species, consistent with the hypothesis that female choice has driven the divergence in male coloration between the two species.

TL;DR: Diversification of the LWS alleles may have originally taken place in riverine environments, with a new mutation occurring subsequently in Lake Victoria, suggesting the adaptation of A2-derived pigments to depth-dependent light regimes.

TL;DR: This paper examined genetic structure among five species of Lake Victoria haplochromine cichlids in four island communities, using a full factorial sampling design that compared genetic differentiation between pairs of species and populations of varying morphological similarity and geographical proximity.
