A possible origin of life in nonpolar environments

Abstract

Explaining the emergence of life is perhaps the central and most challenging question in modern science. We are proposing a new hypothesis concerning the origins of life. The new hypothesis is based on the assumption that during the emergence of life, evolution had to first involve autocatalytic systems which only subsequently acquired the capacity of genetic heredity. Additionally, the key abiotic and early biotic molecules required in the formation of early life, like cofactors, coenzymes, nucleic bases, prosthetic groups, polycyclic aromatic hydrocarbons (PAHs), some pigments, etc. are poorly soluble in aqueous media. To avoid the latter concentration problem, the new hypothesis assumes that life could have emerged in the nonpolar environments or low water systems, or at the interphase of the nonpolar and polar water phase, from where it was subsequently transferred to the aqueous environment. To support our hypothesis, we assume that hydrocarbons and oil on the Earth have abiotic origins.
