An inquiry on the role of cosmic muons-banded iron formations interactions-induced spin-controlled enantioselective synthesis in the emergence of biomolecular homochirality and implications for the biosphere during weakening in the geomagnetic field

The dominant hypothesis for the origin of life posits that serpentinization is the driving mechanism for the emergence of biomolecules and life in the Precambrian era. The serpentinization of peridotite generates magnetite (iron oxide) and silicate minerals, suggesting that magnetized magnetite-associated spin-controlled reactions could have played a significant role in the emergence of life. The biomolecules of life are homochiral and biomolecular homochirality is coupled with electron spin selectivity. Recent studies proposed that cosmic spin-polarized muons or magnetized iron oxide-induced spin-polarized electrons interactions with mirror symmetrical pairs of chiral biomolecules resulted in the emergence of biomolecular homochirality. In agreement with S. Furkan Ozturk and Dimitar D. Sasselov, PNAS 2022, I propose that the emergence of biomolecular homochirality in the Precambrian era was mediated by spin-control enantioselective synthesis induced by spin-polarized electrons that were ejected from iron oxide-silicate banded iron formations by iron nuclei-derived spin-polarized muons. I also proposed that the coupling between biomolecular homochirality and spin-selectivity suggests that spin-control reactions could also modulate the biosphere after the Precambrian era. Here, I propose and provide evidence suggesting that interactions between aberrant iron nuclei-derived spin-polarized muons and new iron oxide-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 homochiral biomolecules and disease in hominids and other animals.
