for that, the scientists looked to the carbon contained within the ancient dung.editors will review what you’ve submitted and determine whether to revise the article.The city of Eriha in Palestine was dated back to eleven thousand years, and was designated as the first permanent human settlement.Today, archeologists and paleontologists employ this technique to determine the age of organic materials (bones, teeth, wood, etc.) that are less than fifty thousand years in age. The theory is simple: Cosmic particles coming from outer space continuously collide with stable carbon-12 atoms in CO2 molecules, which are widespread in the atmosphere.

however, there are other radioactive isotopes that can be used to date non-organic materials (such as rocks) and older materials (up to billions of years old).Each carbon-12 atom takes up two neutrons and is converted into a radioactive carbon-14 atom.Radioactive carbon-14 atoms rapidly mix and become uniform throughout the atmosphere.In the following years, archeologists used this technique extensively and determined exact dates for pre-historic settlements in the ancient world.Some Neolithic (later stone age) remains were dated back to fifty thousand years in Russia and Africa. These and many similar questions can be answered by carbon dating, a method used by archaeologists and other scientists to discover the age of ancient remains and artifacts. All living organisms on this planet are composed partially of carbon.
