The article offers information on the discovery that nature, not man, produced the first chain reaction. The research and development arm of the French Atomic Energy Commission, uncovered evidences to support a theory that a prehistoric spontaneous nuclear chain reaction took place approximately 1.7 billion years ago. The French team of scientists, working at the Oklo uranium mine in Gabon, Africa, found that uranium deposits at the site contained an abnormally low proportion of uranium 345. Analyses performed by the scientists have ruled out the possibility of accidental contamination of the site.
