Abstract: | It is proposed that high velocity asteroidal impacts with the Earth created polymeric nucleotide sequences out of monomeric nucleotides via direct compressive forces. The developed model describes the simultaneous formation of histone-equivalent proteins and RNA/DNA-equivalent template structures as a natural and expected consequence of bolide impactions with organic material accumulating on the crustal surface of the Earth approximately 3.8-3.5 billion years ago. It is shown that literally billions of different gene-equivalent nucleotide sequences, each one having a set of surface-complementary histone-equivalent proteins, might be created in such a manner. It is hypothesized that it is this process that gave rise to the chemical substrate upon which Darwinian selective forces have acted ever since. |
