Germ, weak signal, shaping factor

Signal or indication of a future evolution, that seems very small in its present dimensions but of considerable size by its future consequences. It may be an elementary particle signaling an important trend, like the manifestation of discontinuities and ruptures in the processes of evolution considered a priori as evident. The salient facts of the future are the sets of verifiable observations that seem to have a tendency to weight the likely evolution of this or that human activity.
