  "summary": "Phenotypes evolve through changes in gene regulatory networks (GRNs), but how changes in network topology contribute to phenotypic evolution is still poorly understood. Butterfly wing color patterns provide a tractable system to answer this question. Here, we compared the expression of four color pattern genes, WntA, pdm3, ivory, and Optix, in five nymphalid butterflies, and tested their…",
