I have never believed that chirality has ever been an issue for biology,Stop. That's bad biochemistry. Peptidyl transferase activity within
or my religious beliefs. There is no reason to think that it ever was
an issue for biological evolution. Life uses L amino acids to make
proteins, but they are only the proteins that were created after there
was a genetic code. The peptidase in ribosomal RNA chose L amino acids
as the ones that it could join together into a polymer. D amino acids
do not work for that peptidase.
