Expansion of apical extracellular matrix underlies the morphogenesis of a recently evolved structure

pre-print
One of the fundamental gaps in our knowledge of the evolution of novel structures is understanding how the morphogenetic processes that form these structures arise. Here, we traced the cellular development of a morphological novelty, the posterior lobe of D. melanogaster. We found that this genital outgrowth forms through an extreme increase in cell height. By examining the apical extracellular matrix (aECM), we uncovered a vast network associated with the developing genitalia of lobed and
