CHIRALITY AND THE EQUATION OF BIOLOGICAL BIG-BANG

A non-linear bifurcational-type equation is obtained which describes both crucial steps of the prebiotic evolution and origin of life, namely: (1) the spontaneous breaking of the mirror symmetry in the initial racemic monomeric medium and the achievement of its chiral purity (eta almost-equal-to 1); (2) the achievement of absolute (enzyme-like) enantioselectivity (gamma almost-equal-to 1) by macromolecular predecessors of life which ''automatically'' eliminates the necessity of chiral purity of the medium and secures the subsequent functioning of self-replicating systems even in racemic systems. Just this latter step can be designated as the ''biological big bang''.
