The banality of it all
We have to get used to the fact that chemists are now working normally with unnatural nucleotides that are mutated and evolved (their words). They have created enzymes that can make long enough polymers with all six XNA types that do encode genetic information, and they have also engineered reverse transcriptases. These enzymes can accurately replicate genetic information from DNA to XNA and back, but with enough copying mistakes for functions to evolve.
Evolution has entered a phase where it is irrelevant. No somo nada. (the motto of this blog). How true!
