This essay will gravel with a brief discussion of dating techniques.
In the contract of hominid evolution, two main methods of dating are used: carbon-14 and potassium-argon dating.

This makes this method useful for dating of recent fossils, with good accuracy, up to 50,000 years back. After 5770 years, half of the carbon-14 in a fossil decays to nitrogen-14....If you want to get a full essay, order it on our website:
