What is Reduction of embryonic E93 expression as a hypothetical driver of the evolution of insect metamorphosis about?

## Significance Insect metamorphosis is classified into hemimetaboly and holometaboly, which derives from the former. Hemimetabolan nymphs are similar to the adult, whereas in holometabolans embryogenesis produces a larva that differs from the adult, being vermiform in extreme cases. The embryo of the hemimetabolan __Blattella germanica__ expresses the gene __E93__ at high levels. In all insects, E93 triggers adult morphogenesis in the last juvenile stage, but in __B. germanica__, E93 is also crucial for embryogenesis. Intriguingly, __E93__ expression is high in the embryo of hemimetabolans, but very low in holometabolans. We hypothesize that E93 determines the nymphal genetic program, and that the reduction of embryonic __E93__ expression has been instrumental for the formation of the larva and the evolution of holometabolan metamorphosis.
