Genome Analyses Reveal Diverse Riverine Genetic Contributions to the Lake Malawi Cichlid Radiation.

ABSTRACT: Comparative studies of whole genomes have increasingly shown that genetic introgression between closely related species is surprisingly common across the tree of life, making the description of biodiversity and understanding the process of speciation complex and challenging. The adaptive radiation of cichlid fishes in Lake Malawi, that is characterised by hybrid origins and cases of recent introgression, provides a valuable model system to study the evolutionary implications of introgression. However, many potential sources of introgression into the radiation have not yet been investigated. Here we use whole genome data from 239 species from Lake Malawi and 76 species from surrounding African river and lake systems to identify previously unknown introgression events involving the Malawi ra
