DNA dating is based on the assumption (debated by geneticists) that mutations occur at a constant rate. The accumulated mutations in DNA can be measured, and the time necessary for them to occur calculated. The amount of difference between Neandertal and human DNA suggests that our common ancestor existed about 550,000 to 690,000 years ago.

Radiocarbon dating of bone. Taylor (1992) has effectively reviewed the history of research on problems of radiocarbon dating of bone. Because techniques developed for reliable, accurate, and precise dating are also used for stable isotope and chemical analyses, it is appropriate to summarize this history here.

In archaeology, it is not always possible to identify bone fragments. A novel approach was chosen to assess the potential of histology as an identification tool in those instances in which macroscopical study (e.g. by means of bone surface texture) has failed.

Over 3,000 years ago, the Chinese used animal bones to help make important decisions. To use an oracle bone, a diviner made two statements, one positive and one negative. Each oracle bone had two halves, a positive one and a negative one, with holes bored in each half. When the holes were heated with a burning stick, the bone cracked.

AbstractAfter a 20-year hiatus (1955–1975) during which few archaeologists discussed fluoride dating, the method again received attention in the 1980s and 1990s when some argued for its validity. As a dating method, fluoride dating depends on the rate at which fluorine ions replace hydroxyl ions in osseous tissue. The rate of replacement is influenced by the properties of the skeletal part
