According to Higham (1999) C14 method can be described as ‘the radio carbon revolution’ which has significantly impacted our understanding about evolution and also cultural emergence of human species.

The Method of Carbon-14 Technique Archaeologists rely on the various radiometric dating techniques- based on the radioactive properties of unstable chemical atoms to determine the age of the materials. In the biosphere carbon-14 is created by the collision of a neutron, exited by the cosmic ray collides with a nitrogen atom.

Researchers from the field of Physics have discovered that radioactive molecules are unstable and they undergo decay to attain a stable structure at a specific rate which is directly determined by the atomic number and mass of the decaying atom (Polach, H. The isotope of carbon thus produced is radioactive and it will undergo decay at a constant rate (Berger and H. The carbon isotope is also absorbed during photosynthesis by plants and reaches animal body when they consume plant parts.

Conclusion Despite all the limitations radio carbon dating will remain as a significant tool for archaeologist around the globe to compare and understand the evolution of human culture and civilization. Thus undoubtedly radiocarbon dating remains one of the significant tools for the archaeologist to explain the evolution and cultural emergence in a more accurate manner.

Advancements in this field like accelerator techniques of carbon-14 dating (C.

But studies have showed a slight fluctuation in this ratio over the millennia and hence there is a possibility and consequent discrepancy in calculation too (Currie).

Another limitation is the difficulty in estimating the age of things which are older than 50000 years as the amount of C-14 in such samples become absolutely undetectable due to complete decay. F Herzog 60) conducted with the help of mass spectrometer have increased the range of the technique up to 100000 years (Nave).

Archaeologists utilize one of the revolutionary methods called the radio carbon dating to determine the approximate age of the organic materials including plant and animal parts up to 50000 years (Long).

Radiocarbon dating technique is primarily based on the radioactive decay of Carbon-14 isotope.

The carbon dating technique takes the assumption that all livings have fairly same percentage of 14C isotope in their body and also that the ratio of carbon-12 to carbon -14 present in the biosphere and inside the living plants and animals remain constant.

After the death of the organism the carbon intake is stopped.

Radiocarbon dating enable archaeologists to provide proof of authenticity to the excavated artifacts’ period of usage and thus by collaborating with the efforts with historians and anthropologists, the unwritten history can be precisely explained.
