BEYOND THE UPWARD CURRENT. “Transport from the troposphere to the stratosphere is also well described. It should be stressed that the transfer of dispersed particles from the troposphere to the stratosphere is possible not only during/via catastrophic events (volcanic eruptions, forest fires), but also during the passage of vortex areas where the troposphere dramatically changes its height.” https://lnkd.in/dNHWs6R View in LinkedIn

VERIFIED LOWER UPWARD CURRENT. “Aerosol transport, including living organisms, from the Earth’s surface to the troposphere is well described. The examples of bacterial genera, which can be attributed to the aerobes of troposphere, indicating the transport mechanisms from the surface of the ocean and land, are presented in the third line of Table 2.” https://lnkd.in/dNHWs6R View in LinkedIn

FURTHER WORK NEEDED. “Of course, this phenomenon needs further exploration, perhaps sequencing of other genes of bacteria from this genus. However, we can state that the upward transport of bacterial DNA is one explanation of the close similarity.” https://lnkd.in/dNHWs6R View in LinkedIn

SIMILAR TO TERRESTRIAL ORGANISMS. “Phylogenetic dendrogram (Figure 4) shows that the DNA sequence discovered in samples of cosmic dust has 93% identity with two of the five Mycobacteria sequences found in the samples from the marine surface micro layer and marine aerosol in the Russian Western Arctic.” https://lnkd.in/dNHWs6R View in LinkedIn

THE NUT OF THE PROBLEM. “However the transport of such material above 30 km is not well documented. If there can be a migration or diffusion of bacterial particles above 30 km, this supports a hypothesis in which living matter is not required to be brought in with meteoritic or cometary material to the Earth but, on the contrary, is dissipated from the Earth biosphere into interplanetary space. The data also supports the possibility of microorganisms coming to the Earth from outside the Earth.” https://lnkd.in/dNHWs6R View in LinkedIn
