[BPT06-01] three-step evolution of primordial life
Keywords:origin of life, birth of life, primordial life
First, proto-life appears underground as ectosymbiotic biofilms, facilitated by high-energy aqueous electrons from a natural nuclear reactor. Second, proto-life evolves by utilizing solar energy to survive on Earth’s Hadean surface in lacustrine environments. Finally, third proto-life, which is the first life on the Earth, emerges after struggling against the effects of a toxic Hadean ocean.
These stepwise evolution was the result of environmental changes through time. First proto-life born underground could survive with abundant energy from a natural nuclear reactor, however, they need to fit to the Hadean surface environment through splashing of nuclear geyser, resulted in the evolution to second proto-life. Finally, second proto-life encounter the toxic ocean as a result of function of plate tectonics, then first prokaryote was born. Thus, the birth and evolution of life is a response against these environmental changes, and life’s evolution is closely interlinked with the environment.
