Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.Libby thus reasoned that by measuring carbon 14 levels in the remains of an organism that died long ago, one could estimate the time of its death.
Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms. Our Living Language : In the late 1940s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred.The controversy didn’t end quite there, as it was later discovered that during the only time Tyson mentions the word evolution in this episode, a Fox station in Oklahoma cut out to a promo before returning to the show, sparking outrage in the scientific community for censoring the show.The station later claimed this was a complete accident, but many remain skeptical. Are we more advanced than our ancestors or are we actually in decline? How can I briefly explain to a person knowledgeable about Evolution why and how to believe in Creationism? What are your thoughts of using purely scientific arguments like these that omit any reference to “God”? Isn’t the evidence of our expanding technology proof of the evolution of human brain development?
