Phenomenon of microbiological expansion in Archaeozoic era as a precedent of search and interpretation of extraterrestrial analogues

Abstract

Morphological, biogeochemical and isotopic evidences of microbiological life on the early Earth starting 3,8 milliard years ago are discussed. A renewed paradigm of biological activity discovered in meteorites and preserved in the an cient sedimentary rocks by means of modern methods gives an opportunity to use accumulated experience of specialists for search and interpretation of extraterrestrial analogues.
