Question 4: short remarks about the origin of homochirality.
These short remarks about the origin of biological homochirality are focused on the questions related to the origin and selection of homochiral polymers and the broken mirror symmetry. They are important questions, but still equally unanswered, since the answers, I believe, closely relate to the evolutionary paradigm we accept. The prebiotic evolutionary paradigm, as it seems to me, should be based on idea of "progressive evolution of structural and functional complexity," and the typical combinatorial constraints similar to the error catastrophe, which come into being due to the very complexity, must not appear here.
