Here is the full quote : "Resolving many evolutionary, biostratigraphic, and paleoecogic questions requires detailed stratigraphic sampling and assumes that the stratigraphic oder of fossils bears some relationship to their chronological order."
Note the critical word assumes. By definition an assumption cannot be proven right or wrong, so how does one test it as we weren't there when they became fossils? |
An assumption cannot be proven right or wrong? Nonsense! We all do this all the time. This morning, I assumed there was milk in the fridge, I assumed my son's preschool would be open when I dropped him off, I assumed my bus would show up on time, I assumed John downstairs would know my coffee order without my having to say anything...
All assumptions, in the sense that I didn't carefully think through all the possibilities before making any decisions. All informed by prior evidence. All subject to revision in the light of new evidence.
Just like the fossil record. The ages of fossils and/or their surrounding rocks can be dated radiometrically, and hence we have a pretty good idea of the age of any rocks that we find containing, say, Triassic fossils. That means (our assumption) we don't have to date every single Triassic fossil we ever find. Just like I don't have to check the date on the milk every single morning.
But our assumption can easily be tested. We could date the rocks, but we could also falsify our assumption in other ways. For example, if we found Triassic rocks with Oligocene strata below them and Cretaceous strata above them, or typical Oligocene, Cretaceous and Triassic fossils in the same rock (as the global-flood hypothesis would predict), we'd have a serious problem.
So how do you explain the stratigraphic order of fossils?
