The scientific method is all about testing and retesting theories since no theory is ever proven by science.
The scientific method can only disprove theories or increase the power of previous predictions that have yet to be disproved, but it can never absolutely prove anything to be absolutely true.
Radiometric dating and many other techniques are used to support the idea that this transformation process took tens and hundreds of millions of years.
For most scientists all of this seems so obvious that it is difficult to question.
Certainly this seems like a difficult and rather mysterious problem for those, like myself, who might think to question the long age notion of the fossil record.
At least a partial explanation might be found in the fairly recently discovered fact that at least some nested hierarchical patterns to the distribution of different populations (both living and within the fossil record) seem to be strongly related to ecological and population-size factors.
If contamination is really to blame for these results, then why does it appear in such supposedly old material as well as in delivers good entertainment as long as viewers overlook its bad science.
This pattern arises when species that appear on few islands occur only on the islands with the most species, while only the most widespread species are found on the islands with few species (Wright et al., 1998).Therefore, the best thing to do in science is to continually question and test previous hypothesis and theories to see if they continue to hold up under scrutiny.So, let's take another look at the available evidence and see if any other possibilities present themselves.The nested subset pattern arises because species differ in their distributions across space.Some species use a wider range of resources or persist across a wider range of habitats than others (Brown, 1984; Brown et al., 1996; Hanski and Gyllenberg, 1997).

This has been argued before, but the testing process itself is loaded with procedures that rigorously remove contaminants.
