Fossilized dental remains found in England in 1964 that were previously thought to be Neanderthal were found in 2011 to actually be human. That startled the

scientific community, as they showed that modern humans lived in Europe over 6000 years earlier than it was previously thought. The testing indicated that

0.39% of the carbon-14 remained. How old were these remains? Round your answer to two decimal places, if necessary.

Use the carbon dating formula, f(x) = 4,2-0.0175x, where A is the initial amount of carbon and I is the number of centuries (100 years) since the carbon-14

began decaying.

The remains were

centuries old.
