Fossil strata dating
No wonder the laboratories that “date” rocks insist on knowing in advance the “evolutionary age” of the strata from which the samples were taken—this way, they know which dates to accept as “reasonable” and which to ignore.
Essentially nothing of evolutionary significance is believed to have occurred in this “short” time frame.The so-called “absolute” methods of dating (radiometric methods) actually only measure the present ratios of radioactive isotopes and their decay products in suitable specimens—not their age.These measured ratios are then extrapolated to an “age” determination.These radiometric “clocks” begin keeping time when the molten rock solidifies.
Since fossils are rarely found in igneous rocks, one can only date lava flows that are occasionally found between layers of sedimentary rock.This is an outrageous case of circular reasoning, and geologists are well aware of the problem. The geologist has never bothered to think of a good reply, feeling the explanations are not worth the trouble as long as the work brings results (American Journal of Science 2).
