Wings, Horns, and Butterfly Eyespots: How Do Complex Traits Evolve?


......This work is difficult and time consuming, but the question at its core—the genetic origin of new and complex traits—is probably still one of the most pertinent and fundamental unanswered questions in evolution today. At stake is the possibility of testing whether novel complex traits arise from a gradual building of novel developmental networks, gene by gene, or whether pre-existent modules of interacting genes are recruited together to play novel roles in novel parts of the organism.
