One naturally assumes that the cosmic bombardment responsible for this transmutation remains constant over the millennia.
The carbon 14 present in the atmosphere is constantly renewed.An event is not any more intrinsically intelligible or unintelligible because of the pace at which it moves.For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one."*G. Chesterton (1925)."The theory of evolution gives no answer to the important problem of the origin of life and presents only fallacious solutions to the problem of the nature of evolutive transformations . We are condemned to believe in evolution, but we will always search for a suggestion concerning the methods of transformations . Perhaps we are now in a worse position than in 1859 because we have searched for one century and we have the impression that the various hypotheses [of how evolution could have occurred] are now exhausted.Second, generation of living organisms from non-living matter, or origin of life.This will be covered in the chapters, Primitive Environment (chapter 9), and DNA (chapter 10).If you're seeing this message, it means we're having trouble loading external resources on our website.

ARTEMIS/CEA The measurement of carbon-14 activity requires to collect a sufficiently large of the fossil. There are a trillion times less (10 to the power -12) of carbon-14 radioactive than carbon-12.
The cosmic rays originating from the Sun collide with nuclei in the upper atmosphere and are capable of breaking off individual neutrons.
These neutrons, once freed, can interact with atoms of nitrogen 14 in air, causing the expulsion of a proton and the formation of carbon 14.
This latter serves as a shield against all cosmic radiation - when its strength goes down, the bombardment increases, as does the number of carbon 14 atoms.
