Darwin's theory says nothing about how the first one or a few organisms arose. Evolutionary theory says nothing about how the first imperfect replicator arose.
I'm a bit astonished that regulars here have missed that point.
Darwin leaves it as unknown as to how life arose. Evolutionary theory is about changes in already living things. Yours is a common misunderstanding.
Crash, you did somewhat imply that the code was universal and more strongly that the mitrochondria were the exception (with no hint there were others).
You're getting a bit cranky sounding over simple nit pick where you did leave the wrong impression.
