Studies such as this are fundamental to determining not just how the environment has changed thanks to human manipulation, but also to natural changes due to fluctuations in the environment and climate.
Radiocarbon dating is profoundly useful in archaeology, especially since the dawn of the even more accurate AMS method when more accurate dates could be obtained for smaller sample sizes. It is presumed that the proportion of atmospheric 14 C is the same today as it was in 10 , 11 and that the half-life remains the same. The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left. It has been fundamental, especially in Europe, to demonstrating how landscapes are relics and monuments in themselves and are worthy of study as such. After this point, other Absolute Dating methods may be used. Radiocarbon dating is simply a measure of the level of 14 C isotope within the organic remains 8. The growing importance of our towns and cities means they are now a subject
