Accuracy of fossil dating methods stephen jenkins dating
However, because of severe dating problems which are seldom mentioned, this alleged sequence cannot be maintained.
To present the fossil evidence as a relatively smooth transition leading to modern humans is akin to intellectual dishonesty.
However, these alternative methods have serious problems of their own.
Of the 84 anatomically modern Homo sapiens fossil individuals dated by evolutionists beyond 40,000 years, 59 of them (70%) fall into this 40,000-to-200,000 ya gap.
This problem period may be even larger because: (1) some dating authorities believe that the effective range for K-Ar doesn't begin until about 400,000 ya, and (2) many of the older fossils are found at sites that lack the volcanic rocks necessary for K-Ar dating and hence cannot be dated by this method at all.
Although young-earth creationists challenge the legitimacy of all of the dates obtained by the long-term radiometric methods, even evolutionists are beginning to admit that this dating gap presents a problem for them.
This coverage gap lies beyond what is considered the effective range for radiocarbon and prior to what is considered the effective range for potassium-argon.
(Anatomically modern Homo sapiens fossils that are dated more recently than 40,000 years of age are not of great significance for evolutionary purposes and are not under consideration here.) There are four Neanderthal fossil individuals that are dated more recently than 40,000 years.
They are the Amud I and Shukbah remains from Israel and the Saint-Cesaire and Arcy-sur-Cure remains from France.
Because bone is porous, it is subject to ground-water leaching.
Hence, the method fell into disfavor because it gave questionable dates.
This new method, announced in the journal, Science, involves racemization of amino acids in ostrich eggshell.
