This analyze will lead take with a brief treatment of dating techniques. In the beak of hominid evolution, two briny methods of dating are use: carbon-14 and potassium-argon dating.
Carbon-14 dating involves the decay of radioactive C-14, which has a half heart of 5770 years. This makes this method useful for dating of recent fogys, with good accuracy, up to 50,000 years back. After 5770 years, half of the carbon-14 in a fossil decays to nitrogen-14. Since the ratio of carbon-12 to carbon-14 in a living organism body the same as i...If you expect to get a nevertheless essay, order it on our website:
