Chiral-induced spin selectivity provides a nexus between the geosphere and biosphere: The role of spin-polarized muons and lithospheric iron oxide-silicate rock interactions in the emergence of biomolecular homochirality and the implications for emerging diseases in a weakened geomagnetic field

The dominant hypothesis for the origin of life posits that serpentinization was the driving process for the emergence of biomolecules and life in the Precambrian era. The biomolecules of life are homochiral and biomolecular homochirality is coupled with electron spin selectivity. Recent studies proposed that interactions between mirror symmetrical pairs of chiral biomolecules and cosmic spin-polarized muons (Globus et al., 2020, The Astrophysical Journal) or spin-polarized electrons ejected from magnetized iron oxide (magnetite) bedrocks by solar ultraviolet irradiation (Ozturk et al., 2022, Proceedings of the National Academy of Sciences) resulted in the emergence of biomolecular homochirality. In agreement with those works, I propose that the emergence of biomolecular homochirality in the Precambrian era was mediated by spin-control enantioselective synthesis induced by spin-polarized electrons ejected from iron oxide (magnetite)-silicate banded iron formations by iron nuclei-derived spin-polarized muons. I also proposed that the coupling between biomolecular homochirality and electron spin selectivity suggests that spin-control reactions could also modulate life, including diseases in the biosphere, after the Precambrian era. Furthermore, those spin-control reactions-mediated diseases would exhibit a vibrating drumhead-like spatiotemporal pattern (also known as a checkerboard pattern), semiannual (~6-month periodicity), and quasi-biennial (~2.2-year periodicity) oscillations in synchrony with the activity of a weakening geomagnetic field due to its coupling with cosmic muon intensity. Here, I provide evidence suggesting that interactions between aberrant cosmic iron nuclei-derived spin-polarized muons and new iron oxide (magnetite)-silicate rocks derived from serpentinization in a severely weakened geomagnetic field could result in the generation of an aberrant lithospheric magnetic field that mediates the spin-control synthesis of aberrant chiral biomolecules and emerging disease in the biosphere.
