چکیده انگلیسی
It is supposed that the sequence of the Earth's biospheric revolutions obeys the scaling law. An estimation of the duration of the prebiological chemical evolution as (5-7)Â ÃÂ 109 years is obtained by an extrapolation of the scaling law of the biospheric evolution. The expected scale of time of interstellar prebiological panspermia (â¼0.2Â ÃÂ 109 yr) is much shorter then the estimated duration of the prebiological chemical evolution. The hypothesis of the long prebiological chemical evolution implies that: (a) the prebiological evolution and the origin of life may be a self-consistent Galaxy process and not a process localized on single planets and (b) life has the same chemical base and the same chirality everywhere in the Galaxy.
