If fractionation of this sort had occurred, it would not have
significantly affected any radiometric dating techniques I'm
familiar with.
If it's not too much to ask, where's the evidence that things
happened this way?

Try pushing on the tablecloth instead of pulling it, and you'll

And if you put 100 monkeys in front of typewriters and keep them
supplied with paper, they'll eventually type out the entire works
of Shakespeare.  Any bets on whether Mr. Brown looks like a prophet
before they finish the Sonnets?
