In sum, the processes of evolution create initially comparatively simple dynamical systems on particular levels of organisation. The processes then lead to the progressive complexification of the existing systems and, ultimately, to the creation of simpler systems on the next higher organisational level, where complexification begins anew. Thus evolution moves from the simpler to the more complex, and from the lower to the higher level of organisation
