Just FYI
Vizion28: Mary's own commentary some years later confirm that she NEVER asserted she had an uncontaminated sample to work with, or that she had done all the necessary "slam-dink" tests. She also had only about 19 allele pairs of out multi-millions that an organism carries, so it was a shot in the dark. Near-identical DNA shows up in modern birds, like the wild turkeys that inhabit the Hell Creek site. You been there? I have, with some U. of MT biologist friends. Mary
does confirm, however, that in order to get further funding back then (Note: a sad commentary on some aspects of research science in the US) she had to publish SOMETHING! So this is what it came down to.
But just to confirm here: she never said she'd found dino-DNA. And since then, the entire story has kinda wilted, since there were too many obvious flaws in the work, and no-one has subsequently been able to confirm the idea. Instead, it's been pretty much debunked, but it's also not my job to provide a full-on and detailed educational seminar to unwilling but
Assumptive-Denialist-Creationists (
ADCs! I like it! Let's go with it, n'kay?) beyond my admittedly sarcastic [but nonetheless scientifically valid..] too-long comments that follow. Still; read it if you dare...
Read (from:http://www.barryyeoman.com/articles/schweitzer.html): (broken link)
"Others question Schweitzer's thoroughness.
"The pictures were stunning, but the paper fell quite short," says Hendrik Poinar, a molecular evolutionary geneticist at McMaster University in Ontario. Schweitzer has not proved that the elastic tissue she found actually consists of molecules from the original dinosaur.
Poinar ticks off a list of tests Schweitzer could have conducted, including searching for the building blocks of proteins and then sequencing them to determine their origin. "I understand you want to get your papers out quick and flashy," Poinar says, "but I'm more in favor of longer work with slam-dunk authenticity."
Schweitzer agrees. "I am a slam-dunk scientist," she says.
"I would have much rather held the paper back until we had reams and reams of data." But without publishing a journal article, she says, she could never have hoped for funding. "Without the papers in Science, I didn't stand a chance," she says.
"That's the saddest part about doing science in America: You are totally driven by what gets you funding." Since publishing, Schweitzer has conducted many of the analyses Poinar suggests, with initially promising results.
For a scientist, the ultimate test is having independent researchers replicate your results. So far, there hasn't been a mad rush to do so—few have expertise in both molecular biology and paleontology, not to mention the passion needed to carry out such work. But there is activity. Patrick Orr at University College Dublin is bringing together geologists and organic geochemists to look for soft tissue in a 10-million-year-old frog fossil. Paleontologists at the University of Chicago are setting up a laboratory to look for similar tissue in more T. rex remains; Horner is starting to decalcify other dinosaur bones. In the dinosaur lab at the Children's Museum of Indianapolis, Bakker has taken some peeks.
"I haven't found anything yet," he says, "but wouldn't be a bit surprised if soon somebody comes up with more sticky, bouncy stuff."
Noting that this was all waaaayyyyy back in 2006, the entire issue and controversy has marched on.
Like this, a direct quote from other scientific elements:
"And in fact, many paleontologists are skeptical that Woodward has isolated dinosaur DNA at all. Some flat out don’t believe that it’s possible to recover 80-million-year-old DNA. Others, like Rob DeSalle of the American Museum of Natural History, who studies DNA from insects preserved in amber, grant that Woodward’s DNA might be that old but doubt it’s from a dinosaur. I am willing to believe they have gotten ancient DNA out of bone because the way they’ve described their experiment seems adequate for obtaining DNA, says DeSalle. But they have simply not shown that they have dinosaur DNA. There is no way. I don’t think there is enough information in the small sequence they have to do this kind of analysis. If they got a lot more sequence and showed that the DNA came out as either the sister group to reptiles or the sister group to birds, then that would convince me."
And this commentary:
"Horner and Schweitzer were cautious about their find. The DNA, they said, might have come from a fungus or plant that had contaminated the bone--either in the ground or in the lab--rather than from the dinosaur itself."
Then this telling commentary, from
Mary's own supervising prof:
"Some scientists had attempted to retrieve DNA from insects in amber, and unfortunately, they had not found it possible. In 1993, when the movie was released,
my graduate student Mary Schweitzer and I got a National Science Foundation grant to attempt to extract DNA from a Tyrannosaurus rex skeleton.
Alas,
we didn't find DNA in the dinosaur either, but Mary went on to discover
soft tissues and even proteins in another T-rex we excavated in 2001.
But even though we didn't find DNA in an extinct dinosaur, I decided to see if we could retro-engineer a living dinosaur -- all birds are living dinosaurs -- and make it look like an extinct dinosaur."
Hmmm. The DNA soup thickens, but then we have the dedicated
ADC types. [Wow! Quite the intellectually at-odds combo, huh?][/b] who regularly debunk and criticize
all scientific studies that uniformly
confim that dinosaurs existed, but
only multi-millions of years ago. According to the
ADCs, all, and I mean
ALL, of science's combined, replicated, peer-reviewed and independently done work is
ALL (I gotta use that word often since the
ADCs do as well) inherently biased, fraudulent and off-base.
And yet, along comes a study that, by it's author's own subsequent admission, was hastily done with the possibility of contamination from birds, amphibs, etc., and where she does not then ever
conclude it WAS a dinosaur's sample, or that she had actually found DNA, and suddenly,
why...
Science is Golden! (but its a limited-time engagement, so hurry and get your pet theories in!)
But..
.so.. then...
uhmmm... are
ALL those radioactive & other atomic and molecular studies [not to mention they are
ALL buriied and then
found far deeper/older in
any undisturbed geological columns...] on the ages of dinosaurs and other ancient artifacts
ALL rubbish? Even when the ancient multi-million year old dates are independently confirmed but by
significantly different but also well-proven dating & aging methodologies?
Wow! How fascinating! Why, why... its a
VAST Global World-Wide Science Conspiracy!! You betcha,
Vizion!
Or, does science work just fine
in some labs, but
not in others? Or is it just the stuff you don't like that's
ALL faulty, and just not the work of a grad student hoping for better funding?
Just curious. As a career and professional scientist who has done lots of research & publishing, and who knows that yah can't just get away with anything you want to say, I'm very interested in The Truth as you see it!
This is, of course, unlike the Creationist Religion who doesn't seem to want or need to verify
anything.
ALL their stuff is summarily irrefutable I'm assuming.
Well, you know: I'm just curious. Lemme know my dear lad. I have an
Inquiring Mind!

And just btw; archeologists
regularly find animal bone fragments in old firepits that we dig down to uncover [ oh, and then radio-carbon or Pot-Arg or Fission-tracking or X-Ray Fluorescence
and on and on...] date
("But that's ALL wrong too, I tell you!").
To date,
anywhere on this planet, no-one has
EVER found such artifacts, despite those guys and girls having uncovered literally tens of thousands of such pits and communal living sites showing early hominid social cultures and activities, tools and weapons and bone fragment evidence of what they were eating. But... guess what
type of animal bones we've
NEVER found? Go ahead: guess!
(Also noting that what they have found, for example, are wholly mammoth bones with spear tips in them! Ouchy! Unlikely that those tips were from anyone else but an evolving local hominid. Then we also find some cultural firepits and camp sites near creeks, etc., where we also find identical spear points in various degrees of manufacture, that also (OMG! Here it comes!) Pott-Argon or C14 date to the same age as the ones found in the mastodon's ribcage. Then we find some very primitive hominid skeletons, right there! Pre-ME Jesus-type humans at that! Amazing huh?. You know where all this evidence leads, of course, but you don't want to know. Quite the intellectual conundrum, huh?)

Not one tiny bit of any evidence that shows the use, consumption or interaction between
any dinos
EVER, yet of which there were literally a million different species, many quite small and, being bird-like, (Duhhh! They evolved later to be birds, after all.. DNA confirms
that lineage track!) would have been
very edible.
Yum: Dino Roast!
It's what's for dinner, hunney! But would you first chew the hide offa it for me? My teeth's are all going sorta bad these days....)
Nor have we
EVER found hominid remains in
any T-Rex or other highly carnivorous or predatory dinosaur lizards' stomachs. Assuming the Rex would prob'ly win out in a one-on-one, or even 10-on-one battle...
Sorry, no go.
EPIC FAIL, Vizion28 Far too selective, all of it gleaned from the way out-of-date [2006? My god, man!] articles in various ill-informed and intentionally dumbed down Creationist sites. Not to mention it's wildly illogical at it's every turn, and oh yeah; provably so.
