Many Earth biological processes are immediately linked with the Cosmos, its matter and energy. Cosmic rays, which as noted by V.I. Vernadsky, come from all heavenly bodies, penetrate the whole Earth and everything on it. It is solar rays that dictate the main features of the planetary organisation of the biosphere, provide the free chemical energy, and determine the development of the organic world, cycles, rhythms and the great variety of this development.
