Chirality and evolution
WebJun 5, 2006 · A recent world conference on ‘The Origin of Homochirality and Life’ made it clear that the origin of this handedness is a complete mystery to evolutionists.4 The probability of forming one homochiral polymer of N monomers by chance = 2–N. For a small protein of 100 amino acids, this probability = 2–100 = 10–30. WebNevertheless, chiral reversal could still be a contributing factor to speciation (or to divergence after speciation) when reproductive character displacement is involved. …
