Double abdomen in a short-germ insect: Zygotic control of axis formation revealed in the beetle Tribolium castaneum [Developmental Biology]

The distinction of anterior versus posterior is a crucial first step in animal embryogenesis. In the fly Drosophila, this axis is established by morphogenetic gradients contributed by the mother that regulate zygotic target genes. This principle has been considered to hold true for insects in general but is fundamentally different...
