well back to this noosphere stuff: more here Vernadsky
to quote in part:
In Vernadsky's theory of how the Earth develops, the noosphere is the third stage in a succession of phases of development of the earth, after the geosphere (inanimate matter) and the biosphere (biological life). Just as the emergence of life fundamentally transformed the geosphere, the emergence of human cognition fundamentally transformed the biosphere. In this theory, the principles of both life and cognition are the essential features of the earth's evolution, and must have been implicit in the earth all along. This systemic and geological analysis of living systems complements Darwin's theory of natural selection, which looks at each individual species, rather than at its relationship to a subsuming principle.
