What about independent mutation? could the same mutation occur more than
once in different families? Anything is possible.

I suggest that the M222 mutation could have derived in many families,
based simply on regional exposure to something in their diet, like
potatoes.
Or something that infected them regionally, like a virus. M222 is
simply a trait, and since we do not know what triggers the mutation,
aren't we hanging all of these speculations on a cloud of theory?
