Radiocarbon dating is accurate to about how many years ago Flirt 4 free rooms
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.
However, because ostrich eggshell is thought to be a rather closed system, it is claimed that items found in association with it can be dated more accurately by the amino-acid-racemization method.
The admissions now being made about the dating methods that have been previously used by evolutionists to cover this time period are particularly interesting.
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.
This time period is critical for human evolution, and evolutionists have consistently claimed a degree of certainty in their dating which now appears to be unjustified.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.Because bone is porous, it is subject to ground-water leaching.Hence, the method fell into disfavor because it gave questionable dates.
