Radiometric dating human fossils
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.
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.
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.
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.
