It is impossible to give an evolutionary sequence to the human fossils because there is a coverage gap involving the dating methods which evolutionists believe are the most reliable—radiocarbon and potassium-argon (K-Ar).This gap is from about 40,000 ya (years ago) to about 200,000 ya on the evolutionist's time scale.This new method, announced in the journal, Science, involves racemization of amino acids in ostrich eggshell.The amino-acid method was developed some time ago for dating bone material at archaeological sites.Popular presentations of human evolution show a rather smooth transition of fossils leading to modern humans.The impression given is that the dating of the individual fossils in that sequence is accurate enough to establish human evolution as a fact.These admissions have profound implications for human evolution.In the Science article on ostrich-eggshell dating, the authors state that many of the dates assigned to human fossils in this 40,000-to-200,000-years ago period based on the older methods were only "provisional," and that all such dating is "uncertain." These are remarkable admissions.
To present the fossil evidence as a relatively smooth transition leading to modern humans is akin to intellectual dishonesty.All other Neanderthal remains, some 300 fossil individuals, or approximately 98.6% of all of the Neanderthals, fall into the period covered by this gap.(It is well known that another reason why many of the Neanderthal fossils are poorly dated is because they were found long before the importance of documenting fossils in their geological context was fully appreciated.) The relatively new fossil category created by evolutionists, the "archaic Homo sapiens" category, contains at least 64 fossil individuals.Since the morphology of a fossil cannot be changed, it is obvious that the dating is the more subjective element of the two items.Yet, accurate dating of fossils is so essential that the scientific respectability of evolution is contingent upon fossils having appropriate dates.
