Reaction-diffusion models apply to many relevant biological processes. A brief introduction into general concepts like pattern forming instabilities, activator-inhibitor systems and excitable media and their limitations is given. Calcium waves and Min protein oscillations in E. Coli are given as examples of successful examples of the reaction-diffusion paradigm. An alternative mechanism is illustrated by a short discussion of recent work in modelling of rippling patterns in colonies of myxobacteria.
