Radiocarbon and DNA dating | carbon dating in archeology

Could DNA technology be an alternative to radiocarbon?


Dating or the determination of the period is limited to archaeology. 

The discovery of ancient graveyards or ornaments makes headlines, but such a discovery will be important only if it is known how old they are. 

So when chemist Willard Libby discovered radio carbon dating in 1946, it was a major event for archaeology, and he received the Nobel Prize for that achievement.


Radiocarbon technology cannot be used on any old human body. 

With this technique, only 50 percent of skeletons can be known for a period of time, because some skeletons do not have enough biological material or have become contaminated. As such, DNA dating developed by iran elhike's team is the solution. 

But what is radio carbon dating? 

This technique tells the time period of a biological object based on a chemical reaction.


Carbon is found in all living things. and is the basis of all molecules. We take in carbon while eating and spread it around through exhalation. 

Radiocarbon dating is the process of comparing different isotopes of carbon (a type of atom). 

The most commonly found carbon-12 remains stable in the atmosphere. And the best measure to measure the age of skeletons. Whereas another isotope carbon-14 is radioactive and later it is destroyed at one time. 


Although DNA dating has yielded good results, it is not a substitute for radiocarbon dating, as its accuracy depends on a data set of ancient DNA.


Since the Plants and animals stop taking up carbon-14 after death, so the radioactivity of carbon-14 remaining in them tells their age. But the exact age cannot be told due to the small amount of organic matter, the food of the dead animal or person and the contamination of the dreams. 

Scientists already knew about DNA mutation, which tells who comes from where. There are also such DNA mutations, which tell how long ago someone lived.


Iran elhike's team has developed the Temporal Population Structure (TPL) algorithm tool, time-trace five hundred ancient and modern genomes. Identifies these mutations and describes their timing.

 Although TPS has yielded good results, it is not a substitute for radiocarbon dating, as its accuracy depends on a data set of ancient DNA.
