“Essentially, this means that carbon dating, though a useful tool, is not 100% reliable. For example, recently science teams at the British Antarctic Survey and Reading University unearthed the discovery that samples of moss could be brought back to life after being frozen in ice. The kicker? 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. Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate.”
