Examples carbon dating errors
By testing the amount of carbon stored in an object, and comparing to the original amount of carbon Unfortunately, the believed amount of carbon present at the time of expiration is exactly that: a belief, an assumption, an estimate.It is very difficult for scientists to know how much carbon would have originally been present; one of the ways in which they have tried to overcome this difficulty was through using carbon equilibrium.Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached.
Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought."The radiocarbon dating technique may significantly underestimate the age of sediment for samples older than 30,000 years,” said the authors of the report from the Chinese Academy of Sciences and Germany’s Leibniz Institute for Applied Geophysics.“Thus it is necessary to pay [special] attention when using such old carbon data for palaeoclimatic or archaeological interpretations," they added.It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew: that samples of moss could be brought back to life after being frozen in ice. That carbon dating deemed the moss to have been frozen for over 1,500 years.Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands.
