This estimate, however, is about 18 times longer than the previous “expert” opinion about the longevity of collagen, especially in its quaternary structure. Four million years was already a stretch for many who said soft tissue degrades quickly after death.
Moreover, they thought it could only be preserved for 4my under exceptional conditions of preservation—not on common bones in museum collections.
Amazingly, I It was a little hard to find a website willing to admit this without being Creationist, but National Geographic has an article on it.
Do they figure out the world can’t have lasted as long as Evolution requires because of this fact?
Another noteworthy discovery from the current paper is “structures enriched in carbon.” They write, “Elemental analysis using energy dispersive X-ray spectroscopy (EDS) established that all these structures are enriched in carbon, in contrast with the surrounding denser tissue/cement.” This raises the possibility of running carbon-14 tests on the samples.
None of the authors or reporters mentioned this rather obvious follow-up step.
That question has been niggling at the back of my brain ever since.
