has shown that this bone dates back to 895-1017, which scientists from the University of Winchester believe ties in with the death of the two kings and is unlikely to have come from anyone apart from the father or the son.is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.Archaeologists precisely measure levels of the isotope in organic remains.Knowing the halflife, they back calculate how much time must have passed since the remains had levels identical to living organisms.All living things exchange the gas Carbon 14 (C14) with the atmosphere around them—animals and plants exchange Carbon 14 with the atmosphere, fish and corals exchange carbon with dissolved C14 in the water.

It makes no sense at all if man appeared at the end of billions of years.To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly from each atom.Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.
