Organisms capture a certain amount of carbon from the atmosphere when they are alive. But as the method was refined, it started to show rather regular anomalies. Scientific knowledge itself continues to evolve as new data and new studies help us understand and quantify uncertainty in the natural world. The less there is left, the older the sample.
Again, unlike the common use of the term chaos, which implies randomness or a state of disarray, the science of chaos is not about randomness. However, calibration of carbon levels using tree rings and other sources keep such effects to an extremely small level.
The more accurate carbon clock should yield better dates for any overlap of humans and Neanderthals, as well as for determining how climate changes influenced the extinction of Neanderthals. However, it should be used with caution.
