http://www.boneclones.comhttp://www.actionbioscience.org/evolution/benton.htmlThe rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them:
Millions of fossils have been discovered.They cannot deny that hundreds of millions of fossils reside in display cases and drawers around the world. Perhaps some would argue that these specimens - huge skeletons of dinosaurs, blocks from ancient shell beds containing hundreds of specimens, delicately preserved fern fronds — have been manufactured by scientists to confuse the public. This is clearly ludicrous.
Some skeptics believe that all fossils are the same age.Otherwise, religious fundamentalists are forced to claim that all the fossils are of the same age, somehow buried in the rocks by some extraordinary catastrophe, perhaps Noah’s flood. How exactly they believe that all the dinosaurs, mammoths, early humans, heavily-armored fishes, trilobites, ammonites, and the rest could all live together has never been explained. Nor indeed why the marine creatures were somehow ‘drowned’ by the flood.
Rejecting fossil data cannot be supported by proof.The rejection of dating by religious fundamentalists is easier for them to make, but harder for them to demonstrate. The fossils occur in regular sequences time after time; radioactive decay happens, and repeated cross testing of radiometric dates confirms their validity.
Accuracy of the fossils
Fossils prove that humans did not exist alongside dinosaurs.Since 1859, paleontologists, or fossil experts, have searched the world for fossils. In the past 150 years they have not found any fossils that Darwin would not have expected. New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.
Scientists can use different chemicals for absolute dating:
The best-known absolute dating technique is carbon-14 dating, which archaeologists prefer to use. However, the half-life of carbon-14 is only 5730 years, so the method cannot be used for materials older than about 70,000 years.
Radiometric dating involves the use of isotope series, such as rubidium/strontium, thorium/lead, potassium/argon, argon/argon, or uranium/lead, all of which have very long half-lives, ranging from 0.7 to 48.6 billion years. Subtle differences in the relative proportions of the two isotopes can give good dates for rocks of any age.
Scientists can check their accuracy by using different isotopes.The first radiometric dates, generated about 1920, showed that the Earth was hundreds of millions, or billions, of years old. Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates. A key point is that it is no longer necessary simply to accept one chemical determination of a rock’s age. Age estimates can be cross-tested by using different isotope pairs. Results from different techniques, often measured in rival labs, continually confirm each other.
There is only a 1% chance of error with current dating technology.Every few years, new geologic time scales are published, providing the latest dates for major time lines. Older dates may change by a few million years up and down, but younger dates are stable. For example, it has been known since the 1960s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old. Repeated recalibrations and retests, using ever more sophisticated techniques and equipment, cannot shift that date. It is accurate to within a few thousand years. With modern, extremely precise, methods, error bars are often only 1% or so.
Conclusion: The strict rules of the scientific method ensure the accuracy of fossil dating.Conclusion
The fossil record is fundamental to an understanding of evolution. Fossils document the order of appearance of groups and they tell us about some of the amazing plants and animals that died out long ago. Fossils can also show us how major crises, such as mass extinctions, happened, and how life recovered after them. If the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe. Geologists and paleontologists are highly self-critical, and they have worried for decades about these issues. Repeated, and tough, regimes of testing have confirmed the broad accuracy of the fossils and their dating, so we can read the history of life from the rocks with confidence.
