Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: in , he won a Nobel Prize in Chemistry for the invention. It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.

In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon is a key element in biologically important molecules. During the lifetime of an organism, carbon is brought into the cell from the environment in the form of either carbon dioxide or carbon-based food molecules such as glucose; then used to build biologically important molecules such as sugars, proteins, fats, and nucleic acids. These molecules are subsequently incorporated into the cells and tissues that make up living things. Therefore, organisms from a single-celled bacteria to the largest of the dinosaurs leave behind carbon-based remains.

Erez Ben-Yosef, who since has led the excavations at Timna, on the site of the fabled King Solomon Copper Mines and their surrounding smelting grounds. Elisabetta Boaretto, an internationally recognized leading expert in radiocarbon dating. She generously explains the basics of radiocarbon dating — from its inception until its use today. Through new experiments on year-old olive branches and work discerning their tree rings, Boaretto offers a new resolution to an ongoing debate over the timing of the eruption.
