Accuracy of fossil dating methods Chinese japanese webcam chat

Popular presentations of human evolution show a rather smooth transition of fossils leading to modern humans.The impression given is that the dating of the individual fossils in that sequence is accurate enough to establish human evolution as a fact.This new method, announced in the journal, Science, involves racemization of amino acids in ostrich eggshell.

Nineteen of the 222 Homo erectus fossil individuals (9% of the total) likewise fall into this time gap.

It is impossible to give an evolutionary sequence to the human fossils because there is a coverage gap involving the dating methods which evolutionists believe are the most reliable—radiocarbon and potassium-argon (K-Ar).

This gap is from about 40,000 ya (years ago) to about 200,000 ya on the evolutionist's time scale.

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.
