Abstract
Hexapod basal clades are discussed and their relationships reconstructed based on comparative embryological evidence. Monophylies of Diplura, Dicondylia and Ectognatha is strongly supported but no embryological evidence supports mono-phyly of the Entognatha. The developmental potential of the embryonic membrane (it forms part of the dorsal body wall) suggests that proturans may be basal to all other hexapods
