Eva Nessenius Planetary Embryo Mars Planetenembryo Nessenius
Mars dried out in an evolutionary stage of a Planet-Embryo due to T-Tauri-Eruptions
of the young Sun. Centuries of hot climate made a large part of the water evaporate.
Gases from its atmosphere escaped into space. Most organisms were extinguished. The earth was affected by these heat-disasters too. The worst happened in Permian. The earth was larger than Mars and had some protection by its magnetic field. Flora and fauna were not extinguished completely.
On earth about 70% of the terrestrial vertebrate species and about 96% of the marine species died out. Only 30% of the terrestrial vertebrates and only 4% of the marine
species survived. They became the ancestors for the evolution after Permian.
