The adaptive radiation of cichlid fishes in East Afrian Lake Malawi encompasses over 500 species that are believed to have evolved within the last 800 thousand years from a common founder population. It has been proposed that hybridisation between ancestral lineages can provide the genetic raw material to fuel such exceptionally high diversification rates, and evidence for this has recently been presented for the Lake Victoria Region cichlid superflock. Here we report that Lake Malawi cichlid… 
The legacy of recurrent introgression during the radiation of hares
TLDR
It is shown that ancient hybridization between northern hemisphere species has resulted in shared variation of potential adaptive relevance to highly seasonal environments, including genes involved in circadian rhythm regulation, pigmentation, and thermoregulation.
Pervasive admixture and the spread of a large‐lipped form in a cichlid fish radiation
TLDR
The results suggest a single origin of large‐lips, followed by pervasive admixture and adaptive introgression, with morphology being driven by local ecological opportunities, despite ongoing gene‐flow.
High-quality chromosome-level genomes of two tilapia species reveal their evolution of repeat sequences and sex chromosomes
TLDR
This work inferred two episodes of repeat expansion at LG3 respectively in the ancestor of cichlids and that of tilapias, and suggested that unequal distribution of repeat content that impacts the local recombination rate might make some chromosomes more likely to become sex chromosomes.
Prevalence and Adaptive Impact of Introgression.
TLDR
It is found that introgression plays an important role in adaptive evolution, particularly when a species is far from its fitness optimum, such as when they expand their range or are subject to changing environments.
Biological and trophic consequences of genetic introgression between endemic and invasive Barbus fishes
TLDR
It is attest that the genetic introgression of an invasive congener with native species can result in substantial ecological consequences, including the potential for cascading effects.
Dsuite - fast D-statistics and related admixture evidence from VCF files
TLDR
Dsuite facilitates assessment of gene flow across large genomic datasets by allowing genome scale calculations of the D-statistic across all combinations of tens or even hundreds of populations or species directly from a variant call format (VCF) file.

Repeated colonization and hybridization in Lake Malawi cichlids.
Ancient hybridization and phenotypic novelty within Lake Malawi's cichlid fish radiation.
TLDR
Preliminary analyses support the hypothesis that ancient hybridization occurred within the Lake Malawi cichlid radiation, that the event occurred before the radiation of a species group adapted to low-light benthic habitats, and that this group went on to dominate the deep-water regions of LakeMalawi.
The genomic substrate for adaptive radiation in African cichlid fish
TLDR
It is concluded that a number of molecular mechanisms shaped East African cichlid genomes, and that amassing of standing variation during periods of relaxed purifying selection may have been important in facilitating subsequent evolutionary diversification.
Whole-genome sequences of Malawi cichlids reveal multiple radiations interconnected by gene flow
TLDR
Genome-sequencing data of all major cichlid fish lineages in Lake Malawi show genomic footprints of rapid species diversification, enhancing the understanding of genomic processes underlying rapid species diversity, and providing a platform for future genetic analysis of the Malawi radiation.
Ancient hybridization fuels rapid cichlid fish adaptive radiations
TLDR
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.
Geographical ancestry of Lake Malawi's cichlid fish diversity
TLDR
It is proposed that ancestors of the Malawi radiation became isolated within the catchment during Pliocene rifting that formed both Lake Malawi and the Kipengere/Livingstone mountain range, before colonizing rivers to the south and east of the lake region and radiating within the lake basin.
Genomics of speciation and introgression in Princess cichlid fishes from Lake Tanganyika
TLDR
It is found that the Neolamprologus chromosomes show centre‐to‐periphery biases in nucleotide diversity, sequence divergence, GC content, incomplete lineage sorting and rates of introgression, which are likely modulated by recombination density and linked selection.
Demography and genome divergence of lake and stream populations of an East African cichlid fish
TLDR
A phylogenetic reconstruction based on genome‐wide molecular data largely resolved the evolutionary relationships among populations, allowing us to re‐evaluate the independence of replicate lake–stream population clusters and identify candidate genes have inferred functions in immune and neuronal systems and show differences in gene expression between lake and stream populations.
Nuclear markers reveal unexpected genetic variation and a Congolese-Nilotic origin of the Lake Victoria cichlid species flock
TLDR
The results of a phylogenetic investigation using nuclear (amplified fragment length polymorphism) markers and a wider coverage of riverine haplochromines demonstrate that the Lake Victoria–Edward flock is derived from the morphologically and ecologically diverse cichlid genus Thoracochromis from the Congo and Nile, rather than from the phenotypically conservative East African Astatotilapia.
