In all, 406 human-fossil individuals which evolutionists feel are crucial in documenting the evolution of modern humans fall into the gap between radiocarbon and K-Ar dating and hence have uncertain ages.Creationists have noted an interesting pattern in evolutionist writings regarding the dating of fossils.Because bone is porous, it is subject to ground-water leaching.Hence, the method fell into disfavor because it gave questionable dates.Evolution places severe demands upon fossils used to support it.
Yet, accurate dating of fossils is so essential that the scientific respectability of evolution is contingent upon fossils having appropriate dates.
However, the real seriousness of this problem seems to elude them, even when they occasionally refer to it in their writings. In the past 15 years, the major focus of human evolution has shifted from the origin of "all" humans to the origin of "modern" humans, and the very time during which modern humans are alleged to have evolved from their more primitive human ancestors is the period covered by this gap.
At least 406 human-fossil individuals are placed by evolutionists in this 40,000-to-200,000 ya time-period gap and hence are questionably dated. The inability of the radiocarbon and the K-Ar methods to cover this time period explains why many alternate dating methods have been devised to attempt to give coverage in this area.
(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.
