[BPT05-01] Cause of accelerated evolution of Earth’s life; four-layered underground robust bio-communities played a critical role for the accelerated genome evolution as a response of mass extinction
Keywords:oxygen level, underground bio-community, accelaration of life's evolution
We have engaged in the decoding Earth history Program over 30 years, and obtained the following six results, (1)Since the birth of life until 4.0Ga, three times of Great Evolution of Life (GEL) occurred, (2)Those evolutions were predominantly controlled by the pO2 increase in the environments, (3)Underground bio-communities are present forming 4-layers with boundary layers, (4)Each layer corresponds to different pO2 levels; the older the lower pO2 , (5)In between the two, where two-way genome biomes are present, although speculative, and (6)These four layers could have been formed during the 3 GEL times, accompanying many mass extinctions. Those were remained as fossil environments where evolution stopped, because of no significant environmental changes, in spite of extremely severe surface environments with frequent mass extinction and resultant accelerated evolution of life.
The result corresponds to the concept of 5-6 Kingdom which suggests the preservation of biological communities with different level of pO2 in environments. Through the Earth history, new GEC occurred with great change of pO2 , the advanced life on the surface suffered mass extinctions due to exponentially decreased pO2, instead the underground microbes invaded to the surface, and evolved there again. This is the entity of evolution of life on the earth. Therefore, the presence of robust 4 layered underground biological communities must have contributed to evolving life on this planet, in spite of severe environmental change of planets over 4.0 billion of years in the Universe, not by death, but evolved thorough GEL at 4.0Ga, 2.2Ga and 0.6Ga.
