The evolution–development interface and advances with the eyespot patterns of Bicyclus butterflies



Studies of the evolution of diversity in colour pattern or morphology have seldom included any analysis of the developmental processes involved in translating genetic variation into the phenotypes influenced by natural selection. This gap is being filled by research on eyespot patterns in the butterfly Bicyclus anynana. This review discusses how data on the developmental genetics of eyespot traits can help in the description and analysis of evolutionary constraints.
