title: Earth's orbital chirality and driving force of biomolecular evolution.
abstract: In our recent studies, it has been suggested that both symmetry breaking (violation) and biological rhythms could be caused by the natural rhythmic right-handed helical force field produced by the Earth's orbital chirality (EOC) (1--3). In this essay, according to the further theoretical and experimental studies, it was suggested that the natural EOC force field could serve as the diving force of biomolecular evolution via the chiral interactions. In addition, the following suggestions also were pointed out: (1) The EOC force field could cause the origin of non-coding repetitive DNA sequences ('Junk DNA') to increase the genomes stability and complexity; (2) The EOC force field could increase the structural order of biological systems via the biomolecular EOC stabilization energy effects; (3) The biological information could be spontaneously produced by the chiral interactions of the protogenes with the EOC force field.
