Spatiotemporal gene expression of tissue that will develop into the adult wings. The spatiotemporal pattern of "wingless" gene expression is determined by a network of regulatory interactions consisting of the effects of many different genes such as "even-skipped" and "Krüppel." What causes spatial and temporal differences in the expression of a single gene? Because current expression patterns depend strictly on previous expression patterns, there is a regressive problem of explaining what caused the first differences in gene expression. The process by which uniform gene expression becomes spatially and temporally differential is known as symmetry breaking. For example, in the case of embryonic "Drosophila"
