Fossil dating – Molecular clock shows wrong time?

molecular clocks evolution dating fossilsMolecular clocks is a fossil dating technique using gene evolution over time.

A new report from Argentina involving Penn State and Cornell University suggests further fossil dating discrepancies between the molecular clock method and geology dating using the radioisotopic analysis method.

Basically the molecular clock idea is that over time there will be mutations of genes. If you have a start date and know how many genetic mutations there are in a certain period of time, then you can calculate the last time a sample of DNA sequence diverged.

Previously molecular clock dating results have shown a time long before the accepted date of the fossils.

However, for years we have seen molecular dates, mostly for very deep evolutionary events, that are much older than the corresponding fossils. This situation has been a frustrating Catch-22 because if the clocks are wrong, no fossils exist that could demonstrate they are wrong.

Molecular clock - wrong recent time?

Now a new study in Argentina has results showing a much more recent clock time.

Molecular clocks based on changes in genetic material - indicate much younger ages for a wide variety of plants found as fossils in southern Argentina than do the solid, geologic dates of those fossils, according to geoscientists who surveyed recent paleobotanical discoveries in Patagonia.

... we looked at many new plant fossils from the extremely productive region of Patagonia, and we found the opposite, that the fossils are much older than the clock dates. In this case, we can definitely say that the clocks are wrong. The fossils prove it.

Molecular clock versus Earth clock - 1 or both wrong?

molecular clock technique fossil dating methodThe problem for the Molecular clock technique is that it is calibrated against accepted fossil dates. As shown above the Molecular clock can only show the correct time when it is the same time as the accepted fossil dates.

They found that most of the fossil dates are significantly older than those determined by the molecular clock data, unless a previous calibration was already very closely related to the target fossil.

But is the Molecular clock wrong on both earlier and later results?

Could one of them be correct which would mean the standard dating of fossils could be wrong or needs modifying?

The other options are that all fossil dating techniques are wrong, or, a specific dating technique could be badly effected by external events especially in an Electric and Catastrophic Universe?
