SYNOPSIS. What can the comparative study of gene expression patterns during development contribute to the study of phylogeny? I discuss the basic properties of gene networks that function in development, using information gleaned from developmental model systems. Using examples from the analysis of anteroposterior, dorsoventral and proximodistal axis formation, I outline how the gene networks that pattern these three axes of development are linked in evolution. Finally, I discuss the types of analyses necessary to further our understanding of how gene networks function in regulating the evolution of morphology.
