Carbon 14 dating summary

(Further, there is a pretreatment process of repeated washes of acid/alkali/acid to remove any outer humic acid and debris.) Therefore creationists have been correct to dispute Mary Schweitzer, Lindgren, et al., as they've tried to explain away as microbial contamination the "modern" carbon in an endogenous biomaterial Mosasaur bone. (See also this post from a committed evolutionist in a battle royale with our old friend at the forum run by RSR host Fred Williams.) Regarding Libby's "no known natural mechanism" way of contaminating collagen, here's our RSR explanation of why this is.

If a specimen is purified to 95% collagen, or 98%, or 99%, etc., then approximately the same percent of the carbon in the fossil sample will be endogenous (i.e., original to the living animal). Because new carbon atoms will not original carbon atoms in the collagen molecule.

Contamination is not only far more unlikely within deep-mined and unbroken diamonds, but because of the unique physical composition of diamonds, various kinds of contamination could be more readily detectable.: Just as forensic accountants can often determine when a criminal business has cooked its books merely by doing a Benford statistical analysis of the numbers, so too mathematicians have demonstrated that statistical analysis can indicate whether scientific data is likely a result of measurement errors.

And consider this from a peer-reviewed paper in a respected scientific journal, "at a constant 10°C (the approximate mean annual air temperature in Britain today) it will take between 0.2 and 0.7 Ma for levels of collagen to fall to 1% of their original concentration in an optimal burial environment." * Getting Graded: An expert on radiocarbon dating, long-time assistant professor at Loma Linda University, Dr. The teacher corrected a couple points and clarified a few others.

The assumption by evolutionary geophysicists proposes that the 14c in diamonds, coal, etc., must have come from neutron capture by carbon-13 or nitrogen-14.

Theoretical physicist Lawrence Krauss told RSR's Bob Enyart ( that 14c in allegedly million-year-old specimens is an "anomaly." However, an anomaly is something that deviates from what is standard, normal, or expected.

As a result of decomposition, to the extent that original carbon atoms were falling out of the tissue (so to speak), then to that extent you would no longer have collagen; rather, to that extent you would have humic acid.

Decomposing collagen cannot be "repaired" by free carbon atoms happening upon the decomposition.
