According to the testers “The vessels soaked in the hemoglobin solution, produced by lysing red blood cells, “remained intact for more than 2 years at room temperature with virtually no change. This represented a 200-fold increase in stability in the presence of hemoglobin, Schweitzer reports, confirming hemoglobin’s tissue fixation properties and supporting the possibility that iron could thus, under the right conditions, protect biomaterials (tissues, cells, and molecules) from degradation over deep time.“
But can iron chelation preserve soft tissue and even keep it soft for millions of years?
Again, it's not literally soft, I've told you as much, it became pliable when exposed to the chemicals used to clean out fossils. It's not like you break open a Triceratops femur and meat as fresh as ham from the local deli plops out. Also, I looked more into it, and the process by which the T. rex tissue was found was due to the person cleaning the fossils actually making a mistake. That is, if there hadn't been that tissue there, she would have probably been fired for irreversibly damaging a T. rex fossil.
While a 200-fold delay in the decay of ostrich blood vessels is certainly impressive, even that level of preservation can’t hold a candle to the 99,800,000-fold increase in chemical stability needed in the millions-of-years evolutionary scenario. Schweitzer quite reasonably makes a comparison to the fixation properties of formaldehyde. Many variables influence the degree and duration of the decay-delaying properties of formaldehyde. But specimens preserved in formaldehyde are not preserved perfectly or permanently. While burial conditions likely influence the efficacy of iron as a preservative in any given bone, there is certainly no reason to propose that iron could preserve the molecular structure of soft tissue for millions of years any more than formaldehyde could.
You are presuming that the molecular structure is entirely intact, when it isn't. The preservation is highly imperfect, and it is notable that it is entirely connective tissues that seem to make it.
Also, that's not what it said: it was a 200 fold increase in the stability of the vessels in the presence of hemoglobin. Plus, in a little over two years, the vessels were indistinguishable from when they were first treated, so I think that experiment would have to go on at least long enough to observe some decay before an accurate measurement of the preserving properties of hemoglobin on connective tissue could be assessed, don't you?
The common thread running through “many exceptionally preserved fossils,” Schweitzer notes, is the presence of iron, which is found in hemoglobin.
And a 200 fold increase would put them around 20,000 to 40,000 years, far short of your 99,800,000 fold increase needed.
I'll mention again that our knowledge of preservation is imperfect, and I've said my piece on how I don't think 2 years was sufficient to determine how well hemoglobin could preserve connective tissue.
And collegen, and pigments. And I believe it is much more than 5 now, but papers are scarce until they make up their minds if it’s fact or fiction. Half are arguing its contamination because they still don’t accept that a 200 fold increase can explain the 99,800,000 fold increase actually required.
No, they say contamination because the material is rather similar to living organisms, with the T. rex "soft" tissue being very structurally similar to that of a chicken. Even though I support evolution and the model that birds are descended from bird-hipped dinosaurs, I find it a little bit suspect that the tissue in the T. rex was structurally very similar to bird meat I could easily find in my refrigerator. I mean, I understand the mastodon being structurally similar to an elephant, given how closely related they are, but for an 8,000 kg T. rex to have a similar connective tissue structure to a less than 1 kg animal seems off. From a person that poured a material onto a fossil that would have destroyed the mineral components of the fossil. Yeah, I understand why someone might be skeptical about that whole situation. I personally trust that if the tissue was fraudulent that it would have been caught as such by now, but skepticism is perfectly valid too.
Interesting, but lab tests so far only show a possible 200 fold increase in preservation. Again, far short of the 99,800,000 fold increase actually required. One can speculate all one wishes.
-_- how to replicate a process that takes millions of years in a human lifetime? Plus, while the iron is still heavily present in the tissues, other components key to that preservation process could have themselves ironically decayed faster than the tissue did, or decayed once exposed to open air. Here's hoping more fossils like this are found, to hopefully shed more light on the process.
So evolution is only one possibility and not certain?
The change in populations over time is the observation the theory attempts to explain, and isn't really contestable. However, the how and why it happens certainly is.
Or that your assumption of age may be incorrect? After all, there are no absolutes, right?
Sure, and I would change my mind if there was more evidence supporting that these fossils were 6000 years old rather than millions of years old. I just don't think our knowledge of tissue preservation is comprehensive enough for the dinosaur tissue to be an indication of the age of the fossil. We can't even figure out why some human bodies seem to defy decay yet.
I guess if you consider 195 million years relatively young. But I agree since they are around 40,000 years old, relatively young.
195 years is relatively young compared to 4.5 billion. Has to be the weirdest age attributed to the planet I have heard. But I'd say too old to call you a YEC.
That’s the same mindset of the twin in motion who could not get one single observation correct. He also believed more time passed for him, when less time actually did.
4.5 billion years because you don’t adjust your clocks for the time dilation that occurred.
Time is relative, we base time as it passes from the perspective of our planet, no more and no less. However, mathematically, the difference between the time on this planet and the time within space at large is very small. However, a story for you, so that I can express my view on this matter as clearly as possible. An astronaut leaves Earth and travels through space at light speed for what he perceives to be 10 years before returning. However, from the perspective the people on that planet, over 1000 years have passed. Is the planet 10 years older, or over 1000 years older? I would say that the planet is 1000 years older, because over 1000 years of events have taken place on it. Thus, even if I could observe the planet, moving in a time state such that a year for me was a billion years for Earth, I wouldn't consider the planet a mere 1 year older if I returned after what I perceived as a year later.
Instead using the slower clocks and slower decay rates of today to calculate what occurred faster and faster the further back you go. You assume it was constant, as the twin assumed time remained constant for him, and again, was wrong in every single observation he made.
In order for these things to occur faster, the motion of the molecules of the planet would have had to be significantly faster. In case you haven't noticed, time doesn't pass significantly faster for Venus than it does Earth, so even if you factored in the planet's molten early years, it wouldn't have resulted in a significant enough time dilation to make 4.5 billion years out of 195 million.
Next time you bring this up, I'm going to present it to a physics major and watch them rage over how off you are about time dilation.
