Old samples contain much less C14, so the measured date of older samples is strongly affected by even small amounts of contamination.

Nice link! The above quote is another way of saying, "Noise floor from contamination."

I didn't come to FR to argue evolution.

I just want to go on record as saying that a Staunch Conservative (and I'll match my voting record against anyone here) can also believe that the Theory of Evolution is as solid a scientific theory (and in fact more solid) than the Theory of Gravity.

(We know more about how evolution works than we do about how gravity works.)
