Evolution places severe demands upon fossils used to support it.
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.
It covers roughly the period known as the Middle Stone Age (MSA).
However, these alternative methods have serious problems of their own.Of the 84 anatomically modern Homo sapiens fossil individuals dated by evolutionists beyond 40,000 years, 59 of them (70%) fall into this 40,000-to-200,000 ya gap.However, because ostrich eggshell is thought to be a rather closed system, it is claimed that items found in association with it can be dated more accurately by the amino-acid-racemization method.The admissions now being made about the dating methods that have been previously used by evolutionists to cover this time period are particularly interesting.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.
The result is that the public assumes the dating methods used at any given time are adequate, whereas the dating specialists working with those methods know that this is not necessarily the case.
The latest illustration of not admitting the uncertainties of older dating methods until newer ones have been developed centers around a new method proposed for dating human fossils in this 40,000-to-200,000-years ago time period.
All other Neanderthal remains, some 300 fossil individuals, or approximately 98.6% of all of the Neanderthals, fall into the period covered by this gap.
(It is well known that another reason why many of the Neanderthal fossils are poorly dated is because they were found long before the importance of documenting fossils in their geological context was fully appreciated.) The relatively new fossil category created by evolutionists, the "archaic Homo sapiens" category, contains at least 64 fossil individuals.
Shortcomings of a dating method in current use are not generally acknowledged by evolutionists.
