It seems at least reasonable then that this tree is around 2, years old and that the innermost rings are the oldest rings — right? In the same article, the authors go on to note that radiocarbon dating of these same trees show a statistical accuracy of agreement of only Renfrew, p. For example, from the s questions about the evolution of human behaviour were much more frequently seen in archaeology. The stable isotopes are carbon 12 and carbon
