They determined that the Red Lady was in fact a man, and that the ornaments resembled those found at much older sites in continental Europe.

Radiocarbon dating may only be used on organic materials.Carbon combines with other elements in complex ways to form the molecules that make up our bodies.Most carbon on Earth is not radioactive, but a very small percentage is.Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.
