✦ Synopsis

A network model of development governing the whole temporal and spatial hierarchy of early embryogenesis and pattern formation in Drosophila is introduced. The network is related to a neural network model, with its units being developmental genes mostly connected by the genes' DNA-binding products. The developmental network's agreement with predictions regarding architecture and function of the neural network provides adequate grounds for an analogy between the two. The model is tested through computer simulations-predictions compare favorably with experimental observations. The model not only incorporates a program of control at gene level, but also makes a direct connection with current molecular studies throughout the whole hierarchy of the early embryogenesis of Drosophila.

In many different species it is common for animals to spend large portions of their lives in groups. Such groups need to divide available resources amongst the individuals they contain and this is often achieved by means of a dominance hierarchy. Sometimes hierarchies are stable over a long period o

## Abstract Embryonic development combines paradoxical properties: it has great precision, it is usually conducted at breakneck speed and it is flexible on relatively short evolutionary time scales, particularly at early stages. While these features appear mutually exclusive, we consider how they m

In contrast, almost all cellular networks show the feature of modularity. The popular BA model (Barabasi and Albe
