Abstract

The first phases of the biological evolution on the Earth (prokaryotes) were very long and slow (~2-3 billion years). The last phases of the biological evolution (mammals) were much faster. The evolution of the civilization is even faster. The higher is the organization of the system, the higher is the rate of the evolution. Therefore one may suppose that the 'natural' rate of the planetary prebiological evolution should be even slower than the slowest phases of the biological evolution. Thus the scale of the duration of the 'natural' planetary prebiological chemical evolution may be ~10 billion years (and there is no time for such long prebiological evolution on the Earth of course). We discuss possible mechanisms of the prebiological panspermia in the paper and show by simulation of panspermia wave that the expected scale of time of the interstellar prebiological panspermia is 0.2 billion years (about one Galactic year). It is a scale of time when some competitive prebiological product may infect the most part of the Galaxy. It is much shorter than the possible duration of the 'natural' prebiological chemical planetary evolution. In this situation the prebiological chemical evolution may not be isolated on any single planet from the all-Galaxy prebiological infection. It 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; b) the all-Galaxy prebiological evolution may be highly accelerated as compared with any planetary prebiological evolution due to a very high volume of the evolving matter in the Galaxy as compared with any planet; c) the origin of life may be an all-Galaxy phase transition similar to a second-order phase transition; d) life has the same chemical base and the same chirality everywhere in the Galaxy in the same or similar physical conditions

AB  - The first phases of the biological evolution on the Earth
(prokaryotes) were very long and slow (~2-3 billion years). The last
phases of the biological evolution (mammals) were much faster. The
evolution of the civilization is even faster. The higher is the
organization of the system, the higher is the rate of the evolution.
Therefore one may suppose that the 'natural' rate of the planetary
prebiological evolution should be even slower than the slowest phases
of the biological evolution. Thus the scale of the duration of the
'natural' planetary prebiological chemical evolution may be ~10
billion years (and there is no time for such long prebiological
evolution on the Earth of course). We discuss possible mechanisms of
the prebiological panspermia in the paper and show by simulation of
panspermia wave that the expected scale of time of the interstellar
prebiological panspermia is 0.2 billion years (about one Galactic
year). It is a scale of time when some competitive prebiological
product may infect the most part of the Galaxy. It is much shorter
than the possible duration of the 'natural' prebiological chemical
planetary evolution. In this situation the prebiological chemical
evolution may not be isolated on any single planet from the all-
Galaxy prebiological infection. It 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; b) the all-
Galaxy prebiological evolution may be highly accelerated as compared
with any planetary prebiological evolution due to a very high volume
of the evolving matter in the Galaxy as compared with any planet; c)
the origin of life may be an all-Galaxy phase transition similar to a
second-order phase transition; d) life has the same chemical base and
the same chirality everywhere in the Galaxy in the same or similar
physical conditions
