Take the extinction of Neanderthals which occurred in western Europe less than years ago. Since the s scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings. Organisms capture a certain amount of carbon from the atmosphere when they are alive. The researchers collected roughly metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back years. Various geologic atmospheric and solar processes can influence atmospheric carbon levels. She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating

Carbon dating is used to work out the age of organic material mdash in effect any living thing. Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals demise. ldquoIf you have a better estimate of when the last Neanderthals lived to compare to climate records in Greenland or elsewhere then yoursquoll have a better idea of whether the extinction was climate driven or competition with modern humansrdquo says Paula Reimer a geochronologist at Queenrsquos University in Belfast UK. Follow usThe problem says Bronk Ramsey is that tree rings provide a direct record that only goes as far back as about years. The article was first published on October

Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals demise. The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii work that won Willard Libby the Nobel Prize in Chemistry. But even he ldquorealized that there probably would be variationrdquo says Christopher Bronk Ramsey a geochronologist at the University of Oxford UK who led the latest work published today in Science. .

As a rule carbon dates are younger than calendar dates a bone carbondated to years is around years old and carbon years roughly equates to calendar years. The researchers collected roughly metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back years. Preserved leaves in the cores mdash ldquothey look fresh as if theyrsquove fallen very recentlyrdquo Bronk Ramsey says mdash yielded carbon dates that could be compared to the calendar dates of the sediment they were found in. ldquoIf yoursquore trying to look at archaeological sites at the order of or years ago the ages may shift by only a few hundred years but that may be significant in putting them before or after changes in climaterdquo he says.

Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals demise. By measuring the ratio of the radio isotope to nonradioactive carbon the amount of carbon decay can be worked out thereby giving an age for the specimen in question. Take the extinction of Neanderthals which occurred in western Europe less than years ago. But that assumes that the amount of carbon in the atmosphere was constant mdash any variation would speed up or slow down the clock.
