Third, "various plants have differing abilities to exclude significant proportions of the C-14 in their intake. This varies with environmental conditions as well. The varying rates at which <SUP>14</SUP>C is excluded in plants also means that the apparent age of a living animal may be affected by an animal's diet.  An animal that ingested plants with  relatively low <SUP>14</SUP>C proportions would be dated older than their true age."<ref>''Id.''</ref>

Due to these fundamental limitations, the only scientific conclusion that can be drawn from carbon dating is that material X is older than material Y when X has lost more <SUP>14</SUP>C than Y has.  It is not possible to determine, with any degree of scientific certainty, how much older X is than Y.
