![Bold black letters illustrate amino acids that are deduced as early by the approach, while red letters indicate late additions to the alphabet according to the approach (C* implies possible prebiotic synthesis under specific and narrow conditions [4]). Regular black letters represent amino acids that have not been resolved as either early or late by the approach.
