Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years.
These break down over time in a process scientists call radioactive decay.
Yet when you look into the technical papers on these discoveries, you find that these dates are often questionable and are sometimes clearly in error.
Several types of radiometric dating methods are used today. When a plant or animal dies, the carbon in it has a small amount of radioactivity.
Over time, carbon-14 decays radioactively and turns into nitrogen.
A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally.
When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.
