The carbon dating assumptions need to be pointed out. Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes. Two such things include the following questions: We use carbon, as every living being has carbon.
How carbon dating works?
One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. The only major fluctuation [in carbon] we know of occurred when we began detonating nuclear weapons in the open air, back in the midth century.
For example, a jar starting with all 14C atoms at time zero will contain half 14C atoms and half 14N atoms at the end of 5, years one half-life.
