sex dating cape town - Effective range of carbon dating
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.
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.
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).
