| Abstract: | Biological pattern formation is a process which so far has gone largely unexplained. Experimental biologists favour mechanisms in which morphogenetic gradients are the source of positional information, but among theoreticians the pattern forming processes are believed to some extend to be dependent upon true symmetry breaking processes, which can occur in most nonlinear control systems, of which the Turing mechanism is an example. It is argued here that the common fundamental feature of gene control systems is a high degree of nonlinearity and thus cooperativity, and that this mechanism also is important for the pattern forming processes in early evolution. |
