RESUMO
Butterflies have become prominent models for studying the evolution and development of phenotypic variation. In Heliconius, extraordinary within species divergence and between species convergence in wing color patterns has driven decades of comparative genetic studies. However, connecting genetic patterns of diversification to the molecular mechanisms of adaptation has remained elusive. Recent studies are bridging this gap between genome and function and have driven substantial advances in deciphering the genetic architecture of diversification in Heliconius. While only a handful of large-effect genes were initially identified in the diversification of Heliconius color patterns, recent experiments have begun to unravel the underlying gene regulatory networks and how these have evolved. These results reveal an evolutionary story of many interacting loci and partly independent genetic architectures that underlie convergent evolution.
