Oct 04 Jul 08 May 07 Sep 24 Sep 14 Mar 10 Feb 28 Sep 15 At least to the uninitiated, carbon dating is generally assumed to be a sure-fire way to predict the age of any organism that once lived on our planet. Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable method of determining the ages of almost everything around us.

However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe.

At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it. Specifically, there are two types of carbon found in organic materials: carbon 12 C and carbon 14 C It is imperative to remember that the material must have been alive at one point to absorb the carbon, meaning that carbon dating of rocks or other inorganic objects is nothing more than inaccurate guesswork. All living things absorb both types of carbon; but once it dies, it will stop absorbing.

The C is a very stable element and will not change form after being absorbed; however, C is highly unstable and in fact will immediately begin changing after absorption. Specifically, each nucleus will lose an electron, a process which is referred to as decay.

Half-life refers to the amount of time it takes for an object to lose exactly half of the amount of carbon or other element stored in it. This half-life is very constant and will continue at the same rate forever.

Standards too simplified

The half-life of carbon is 5, years, which means that it will take this amount of time for it to reduce from g of carbon to 50g β€” exactly half its original amount. Similarly, it will take another 5, years for the amount of carbon to drop to 25g, and so on and so forth. By testing the amount of carbon stored in an object, and comparing to the original amount of carbon believed to have been stored at the time of death, scientists can estimate its age.

Unfortunately, the believed amount of carbon present at the time of expiration is exactly that: a belief, an assumption, an estimate. It is very difficult for scientists to know how much carbon would have originally been present; one of the ways in which they have tried to overcome this difficulty was through using carbon equilibrium. Equilibrium is the name given to the point when the rate of carbon production and carbon decay are equal.

Challenges of the method

By measuring the rate of production and of decay both eminently quantifiablescientists were able to estimate that carbon in the atmosphere would go from zero to equilibrium in 30, β€” 50, years. Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached. However, in the s, the growth rate was found to be ificantly higher than the decay rate; almost a third in fact. They attempted to for this by setting as a standard year for the ratio of C to C, and measuring subsequent findings against that. In short, the answer is… sometimes.

Sometimes carbon dating will agree with other evolutionary methods of age estimation, which is great. Most concerning, though, is when the carbon dating directly opposes or contradicts other estimates.

Science education is constantly evolving! want to keep up?

At this point, the carbon dating data is simply disregarded. It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew:. If it does not entirely contradict them, we put it in a footnote. And if it is completely out of date, we just drop it.

News section

For example, recently science teams at the British Antarctic Survey and Reading University unearthed the discovery that samples of moss could be brought back to life after being frozen in ice. The kicker? That carbon dating deemed the moss to have been frozen for over 1, years. Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands. Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.


Age of Humans.


When news is announced on the discovery of an archaeological find, we often hear about how the age of the sample was determined using radiocarbon dating, otherwise simply known as carbon dating.


Most everyone has heard of Carbon dating on the news or elsewhere sometime in the past years.
