Accuracy of dating fossils, about the magazine
In the Science article on ostrich-eggshell dating, the authors state that many of the dates assigned to human fossils in this 40,to,years ago period based on the older methods accuracy of dating fossils only "provisional," and that all such dating is "uncertain. Scientists now use phylogeny, mathematics, and other computations to date fossils. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.
Because bone is porous, it is subject to ground-water leaching.
The relatively new fossil category created by evolutionists, the "archaic Homo sapiens" category, contains at least 64 fossil individuals. One important result is that some older dates may change by a few million years up and down, but the younger dates are very stable.
Other methods were also developed, Phylogenetic trees of species, mathematical models, carbon dating and radioactive isotope dating were also developed. The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them:.
A fossil in an evolutionary sequence must have both the proper morphology shape to fit that sequence and an appropriate date to justify its position in that sequence. Many natural history museums and universities worldwide offer public participation programs in dinosaur events, such as fossil hunting or fossil cataloguing. Educators have permission to reprint articles for classroom use; other users, please contact editor actionbioscience.
The majority of test cases show good agreement, so the fossil record accordingly relates the same story as the molecules enclosed in living organisms. The author does not wish to imply that the ostrich-eggshell-dating method is a legitimate one.
The impression given is that the dating of the individual fossils in that sequence is accurate enough to establish human evolution as a fact. However, because of severe accuracy of dating fossils problems which are seldom mentioned, this alleged sequence cannot be maintained.
This lead to the recognition of one of the principles of geology, i. This gap is from about 40, ya years ago to aboutya on the evolutionist's time scale.
The blog is for people from: This problem period may be even larger because: Creationists have noted an interesting pattern in evolutionist writings regarding the dating of fossils. The strict rules of the scientific method ensure the accuracy of fossil dating.

For evolutionists, the problem is far more serious, but few are willing to acknowledge it. Carbon Dating Carbon dating is the best-known absolute dating technique.
Most importantly, it was recognized that each time-unit was characterized by the appearance of particular fossils. Where are the dates coming from and how is the measurement occurring?
Biologists actually have at their disposal several independent ways of looking at the history of life - not only from the order of fossils in the rocks, but also through phylogenetic trees.
The 'progress' shown by the fossils was a documentation of the grand pattern of evolution through long spans of time.
