Mark Johnson’s paper centres around a provocative and sensible point: the simplicity of a change in evolutionary terms does not necessarily map straightforwardly onto the simplicity of that change within aformal system. This commentary discusses these implications in more depth, making the point that it isimportant to consider the level at which an operation occurs in order to correctly evaluate how complex it is.
