Problems of radiocarbon dating
Because bone is porous, it is subject to ground-water leaching.
Hence, the method fell into disfavor because it gave questionable dates.
However, because of severe dating problems which are seldom mentioned, this alleged sequence cannot be maintained.
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.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.Anyone familiar with the paleoanthropological literature knows that this is not the way most of the dates for fossil discoveries in that time period have been presented.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.

(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.
