The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.
Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.
When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.
The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
