| Popis: | This paper concerns the problem of search of life on other planets due to similarities of some conditions in polar ice caps of Earth and Mars. Viable microbes were isolated from layers of the Antarctic ice sheet that dates back about 200 000 years. Their morphological variability and gradual restoration of some physiological functions in favourable conditions were described. The relation of microbes distribution at different horizons of ice to considerable fluctuations of Earths climate in ancient geological epochs was revealed. Those fluctuations of climate brought to the sharp variations of intensity of microparticles and microbes transfer with intercontinental aerial streams to polar caps of neighbouring planets. |
