TURNING A YEC ARGUMENT ON ITS HEAD — Young-Earth creationists like to tout soft tissues preserved in the fossil record as one of their prime evidences for a young Earth. A closely related issue is the preservation of ancient complex biomolecules, such as DNA, in the fossil record. The Natural Historian blog brilliantly turns this argument around as an evidence against young-Earth creationism: Young Earth Creationism and Ancient DNA. If Noah’s flood was global and created the fossil record (something the Bible nowhere states), and if it occurred only 4300 years ago, then preserved DNA ought to be fairly easy to find throughout the geologic column, from Cambrian through Neogene. It isn’t.
TURN IT ON ITS HEAD AGAIN! — The Natural Historian does it again: Rapid Burial Allows Preservation of a Hadrosaur Fleshy Head Comb.
Rather, what struck me about this rooster-like comb on this hadrosaur is that its existence is more of curse than a blessing for YEC apologists. How can that be? Well, where I convinced that a global flood 4 to 6 thousand years ago were responsible for all the dinosaur fossils, then I should EXPECT to find soft tissues preserved to some extent as the norm rather than the exception to the rule. Why? Because the special conditions that are required for preservation of soft tissues like those found in this hadrosaur are just the kind that should have been produced by a global flood. Combine those conditions with its having happened only a few thousand years ago and you have to ask, why don’t we find skin impressions, remains of feathers, and other impressions of large organs (like these combs) and gobs of biomolecules throughout the dinosaur fossil record?
What I am saying is that if you asked a priori what you would expect to see in the fossil record had a flood destroyed all living flesh from the face of the earth in a short period of time and deposited all those organisms in what we call the geological record? I would expect to find a majority or at least a significant number of dinosaurs to be represented as complete skeletons. I would not expect to find rampant evidence of scavenging and given the fast burial I would expect to find the impressions of many parts of their bodies not just their bones since they would have been covered with their flesh intact. Since this happened not long ago I would expect to find very abundant biomolecules, possibly even intact DNA in the material around the bones, and especially in the bones, even if cells themselves were no longer present.
As I pointed out before this is not what we find in the fossil record. We find some but not much evidence of biomolecules and few cases of soft tissue preservation even if be only the impression of where soft tissues once laid. Just look at mammoths and mastodons from the fossil record. Some of these have abundant cells, DNA, hair and sometimes cellular tissues preserved. If these biomolecules could survive for 4000 years then why shouldn’t animals killed in Noah’s flood just a few hundred years earlier not also be expected to be preserved in a similar fashion?
HOW BILL NYE WOULD HAVE RESPONDED TO HAM IF NYE WERE A GEOCHRONOLOGIST — “45 thousand-year-old fossil wood encased in 45 million-year-old basalt”: Conflict Revisited, from Questioning Answers in Genesis.
Ken Ham’s appeal to young fossil wood within old basalt may have caught Bill Nye off guard, but his claim remains unsubstantiated. The actual radiocarbon ages of this fossil wood were not reproducible by independent labs within analytical uncertainty, suggesting that contamination and/or background interference was responsible for much of the detected radiocarbon. Recent advances in AMS radiocarbon dating have focused on how to account for the fact that contamination is always introduced during sample preparation and how to correct for various kinds of background interference. Regardless, radiocarbon ages close to the practical limit of the method are always treated with some suspicion.
