Carbon dating invented - Carbon - Wikipedia


Carbon-14 is used to date dead plants and animals, because plants and animals incorporate C-14 into their bodies by eating, drinking, and breathing in an environment containing C-14. Through the life of the organism, the proportion of C-14 to C-12 reaches the same proportion as in the rest of the environment. When the organism dies, however, it ceases to incorporate carbon into its body. At this point, and for the years following, the C-14 in the sample begins to decay back into N-14, while the C-12 does not decay. Both C-14 and C-12 are lost as the body decays, but they are lost proportionally , so that the proportion of C-14 to C-12 decreases slowly for thousands of years after the death of the organism.

Carbon occurs extensively in all living organisms as proteins, fats, carbohydrates (sugars and starches), and nucleic acids.
