The paper investigates the evolutionary origin of shell plates and spicules in chitons by analyzing gene expression during early development, finding shared genes but distinct expression patterns suggesting separate origins.

This study investigates the role of endoderm in shell field fate establishment in limpets by disrupting cell-cell contacts and shows that shell field differentiation in the 2q lineage occurs independently of interlineage interactions.

The paper shows that pharyngeal arch segmentation in zebrafish involves simultaneous and sequential processes integrated at PP2, with implications for vertebrate development and evolution.
