Carbon 14 dating half life
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
The best radioactive element to use to date human fossils is Carbon-14.
Below is a chart of commonly used radiometric isotopes, their half-lives, and the daughter isotopes they decay into.
Let's say you found a fossil you think to be a human skeleton.
Perhaps the most widely used evidence for the Theory of Evolution through Natural Selection is the fossil record.
The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
You would need to have access to scientific instruments at this point that could measure the amount of radioactivity in the sample, so off to the lab we go!
After you prepare your sample and put it into the machine, your readout says you have approximately 75% Nitrogen-14 and 25% Carbon-14.
The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.Tags: Adult Dating, affair dating, sex dating
