Evolution is an often surprisingly fast process that results in new adaptations, but also is the mechanism for the origin of novel species. Genetic variation and the resulting changes in an organism’s characteristics are the raw material for selection to act on, which might allow for the evolution of adaptations. My study organisms are cichlid fish, a famous textbook example of exuberant color diversity and record-breaking rates at which new species arise, chosen as a means for understanding the molecular, cellular and developmental mechanisms that drive phenotypic diversity that Charles Darwin already talked about in the “Origin of Species”: “From so simple a beginning, endless forms most beautiful and most wonderful have been, and are being, evolved”.
