Tree ring dating offers over 1,000 years of clues in dates of artifacts from the American Southwest.

Radiocarbon dating provides additional clues necessary for absolute dating.

For centuries, we have been telling ourselves a simple story about the origins of social inequality.

Artifacts from the earliest dates are in the lower levels or strata of Earth.

With the passing of time, new strata form over them.

Thus, the date of an artifact is relative to its location in the levels.

Subsequently, a diminishing field is likely to result in a significant rise in the frequency of radiation induced cancers in the future.

Despite this limitation, paleoanthropologists have found dating by association with polar reversals to be a helpful additional method of tracking the evolution of our fossil ancestors in regions such as East Africa where there has been frequent volcanic activity leaving clear thermoremnant magnetic evidence.
