WebBut there is 99.2% in living things – the C13 is a little depleted, making the ratio a little “lighter” (so-called because C12 is lighter than C13). On Earth the carbon cycle is extensively studied and well understood, so we can look at C12-C13 ratios and draw conclusions about the source, specifically whether or not life is involved.

In geochemistry, paleoclimatology, and paleoceanography δ C (pronounced "delta c thirteen") is an isotopic signature, a measure of the ratio of the two stable isotopes of carbon— C and C—reported in parts per thousand (per mil, ‰). The measure is also widely used in archaeology for the reconstruction of past diets, particularly to see if marine foods or certain types of plants were consumed.
