An identical DNA base pair change has occurred in divergent sticklebacks to alter the expression of a major developmental gene controlling armor plates, thus providing a molecular link between particular enhancer changes, cell signaling, and repeated skeletal evolution in natural populations.
Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.

Regulatory sequences downstream of a key limb identity gene are required for normal sizes of leg bones, and are changed in wild species with dramatic alterations in pelvic structures.
The hadal snailfish rapidly evolved and adapted to extreme deep-sea environments, modifying crucial genes and enhancing tolerance to high-hydrostatic pressure through ferritin gene duplication.

Social information is a process encompassing information acquisition, application and exploitation that is constrained by an individual’s social, behavioural and demographic phenotype.
Whole genome sequencing of 19 populations of Atlantic and Baltic herring reveals hundreds of individual loci underlying adaptation to a low salinity niche or timing of reproduction.

Variation in migration can evolve rapidly and traits that comprise this behaviour may be determined by standing variation at a few regulatory regions that are not common across taxonomic groups.
