  • The Lake Malawi cichlid fishes are an example of extreme vertebrate radiation; however, there is very little sequence divergence among the species. Here the authors present a comparative genome-wide methylome study to suggest DNA methylation played a major role in the extensive phenotypic diversity amongst these fishes.

  • The mechanisms underlying the emergence of novel morphological traits are largely unknown. Here, the authors show that cis-regulatory changes controlling the expression of the fhl2bpigmentation gene are associated with the evolution of egg-spots colour markings in the male fins of a group of cichlids.

  • Analysis of the DNA methylomes of two ecomorphs of Astatotilapia calliptera from a single lake, which diverged about 1,000 years ago plus a third riverine ecomorph, from which they likely separated about 10,000 years ago, shows epigenetic differences associated with altered transcriptional activity of ecologically relevant genes, despite low levels of genetic divergence.
