Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.
Other methods scientists use include counting rock layers and tree rings.
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).
As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.
These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.They claim to have found a footprint in Crete that could change the narrative of early human evolution, suggesting that our ancestors were in modern Europe far earlier than we ever thought.The accepted story of the human lineage has been largely set since researchers found fossils of our early ancestors in South and East Africa, in the middle of the 20th century.All of that led them to conclude that the foot appeared to belong to our early human ancestors, who could have been walking around Europe at an early time than we ever knew.
