In a very dry year growth will be restricted, and the ring narrow, while a wet and humid year will produce luxuriant growth and a thick ring.

By comparing a complete series of rings from a tree of known date (for example, one still alive) with a series from an earlier, dead tree overlapping in age, ring patterns from the central layers of the recent tree and the outer of the old may show a correlation which allows the dating, in calendar years, of the older tree.

A number of 42 representative African baobabs (Adansonia digitata) from Botswana, Zimbabwe, Barbados, Zambia and Sri Lanka were measured and investigated.

Wood sampled from 15 trees were collected (as compared to 5-9 baobabs envisaged).

The field of dendrochronology has developed during the first decades of this century.

Tree-ring dating was the only method of precise age determination until the 1950s, when the radiocarbon dating method was developed.

During the next century and a half, many ancient American Indian sites would be dug up by archaeologists, both amateur and professional, who were unable to determine the actual age of these sites.It is a fascinating chapter in the history of research to observe the immediate interdisciplinary cooperation between tree-ring dating and radiocarbon dating that started in the 1950s and continues up to this day with increasing importance.This chapter presents a brief historical overview of the development of superlong Holocene tree-ring calendars and the calibration of the radiocarbon time scale derived from tree-ring measurements, with a synopsis of the actual stage of research. Doesn’t that give accurate dates of “prehistoric” civilizations?Carbon dating is the ultimate benchmark of the evolutionary dating world.It is assumed that the amount of radioactive carbon left in the sample indicates how old it is. It is based on several assumptions, one of which is false.
