In many ways, this dichotomy in evo-devo research represents a modern iteration of a reoccurring theme in evolutionary biology, where empirical progress in the field has occurred by first focusing on simple traits to establish a basic proof of concept, and then extrapolating these principles to more complex traits that are more readily generalizable across taxa.
