Days old blood that's been out in the weather is probably a horrible source for DNA.
Why don't you tell us? If you can't tell us, why bring it up?
When I am mistaken I will admit it.
What I find hilarious is that we have a lay person (who's entire knowledge of DNA is being gleaned on the run by Google searches) telling a scientist (who uses DNA samples in his work to identify and name new species) how DNA samplying and typing works.It sure would.
It would be hilarious if the DNA fits in a spot where the primate couldn't possibly be like bigfoot.

Sure there is. You simply refuse to consider it. The third way is that YOU, ChrisBFRPKY, are wrong, not us. There's no shame in this, by the way--when I call you ignorant, it's a statement of fact, not a moral judgement (your stupidity--your willful refusal to acknowledge facts--is another matter, but that's not something very relevant to this thread). I'm ignorant about any number of things. My go-to example is electricity--I know the basics, enough to do home wiring jobs, but have no clue how the heavy physics works. If you'd admit your ignorance and errors, it'd be a non-issue.ChrisBFRPKY said:No, when one makes such claims it is either from a lack of education in the field or complete incompetence of the subject. There is no third way.
Well, one potential reason springs to mind: he's got conclusive evidence for this one and not the others. DNA analysis can take some time, after all. Particularly if you're dealing with extremely crapy samples (how long does a PCR run take?).LTC8K6 said:If Smeja's boot sample was part of the project, why release those results and no others?
I'm not a DNA expert and have never claimed to be but, never mind that because the evidence is in Dr Sykes' possession, he is "the" expert.
I would expect Dr. Sykes will be on top of what can be extracted from the DNA and what cannot.
I'm afraid this says an awful lot more about you than it does about Sykes, who is one of the leading scientists in his field in the world. Very highly respected. Frankly, you ought to do better than this.
Let's face it, he wouldn't be the first scientist to go from "highly respected pillar of the community" status to "raving lunatic, possibly dangerous to himself or others" status. The most impressive fall from grace I can think of is Richard Owen, who went from THE leading anatomist of his time to pretty much the way we consider Creationists. Then there's of course Francis Crick. It's sort of cliche for old paleontologists to become philosophers. And it's a basic truism of skepticism that when someone is speaking outside their area of expertise even experts do no better than lay folk.William Parcher said:I'll tell you some more about me. I'm prepared to call him a fool in addition to a nutjob.
ChrisBFRPKY, I am absolutely not surprised that you refused to admit error. That said, you ARE in error on what provides the best DNA sampling. Demonstrably. As in, I demonstrated it. Your refusal to admit you were wrong undermines pretty much everything you've said about honesty and integrity of anyone (and that's about all you've spoken about in regards to those who disagree with you). At this point, it's not unreasonable for us to conclude that either any evidence will be taken by you to support your pet hypothesis, or that you'll refuse to acknowledge the validity of any contrary evidence (that's what you're doing now, so you'll probably do similar in the future).
In other words, you've completely destroyed your credibility here. You don't know the subject, and you refuse to learn.

Also, I love how your references are supposed to automatically trump our references, which at this point include laws, scientific publications, well-known biological facts, and the personal experience of at least three scientists. Sorry, but the real world doesn't work that way. The facts are in our favor. You want mammal DNA, you go to something OTHER than blood. Hair, tissue, bone, teeth, pretty much anything. And you DEFINITELY don't include blood on someone's boots; the mere inclusion of such a sample demonstrates such a shoddy sampling procedure as to call into question the entire process.
Even experts are sometimes wrong.
"We found some DNA in it, but we don’t know what it is. It's not a human, not a bear nor anything else we have so far been able to identify. It's a mystery and I never thought this would end in a mystery. We have never encountered DNA that we couldn’t recognize before." -- Dr. Bryan Sykes, Professor of Human Genetics at the Oxford Institute of Molecular Medicine, 2001
and yet...
"On Saturday, April 28, I had lunch with Dr. Byan Sykes... Sykes also analyzed hair samples from Bhutan attributed to the Yeti, which seemed to defy DNA identification. Interestingly, during our conversation I learned that further efforts were subsequently successful in determining that the hair originated from bear." -- Dr. Jeffrey Meldrum, The Relict Hominoid Inquiry 1:81-82 (2012)
The history of bigfootery is filled with failures but never any bigfoot.
Chris, I would like to suggest a large gathering of skeptics for a banquet dinner with you in attendance. Our challenge is that if you fail to provide biological classification evidence of Bigfoot that is accepted as proof of existence by science, by December 31, 2015, you agree to consume a large portion of the main course.
The main course will be of course, Crow. Clean healthy specimens will be obtained for the dinner. They will be humanely dispatched, thoughtfully prepared and cooked to perfection.
We skeptics will enjoy a main course of steak and accept gracious apologies from you throughout the night. We will of course pay for the banquet, and dining facilities.
Would you be willing to participate?

Oh, and that scientist is doing it wrong.
A perfect example of Bigfoot Science[TM], indeed any Bleever Science[TM].
Ray, I'll accept your invitation if everyone here will agree to accept mine. And since we're now putting a deadline I must amend my invitation to include factual scientific evidence collected by others as well of course. Agreeable?
Excuse me but we were talking about obtaining primate DNA. I've worked with primates before and although I did not perform the actual DNA testing to determine the genetic line of the individuals being tested, each test was accomplished by drawing a blood sample from the subject.
I'll say this again, each DNA test sample was taken from the blood and not the fecal material. Again because the blood was the best source for DNA collection.
The fecal material was used to determine diet and health of the subjects only. If you wanted to see if someone was eating properly or if they were suffering from a parasitic infection you used a stool sample.
There were and are other informations that can be gleened from such samples, but DNA test samples were never taken from the fecal material, only the blood.
Why? Because blood contains tons of DNA. Even in the 80's blood was the top choice of sample used to obtain DNA genetic line information from a subject.
Are there better technologies now? Of course. Are other materials used to obtain DNA samples now? Of course. From what I understand DNA can be extracted from hair samples in this day and age where as before it could not be. How they are doing this is unknown to me and I will not speculate.
I did read the link you provided and it mostly talked about obtaining plant DNA from dung. This was important as to better understand the diet of these now extinct animals. There was some info that suggested they could obtain animal DNA as well although not much was discussed as to how they obtained the animal DNA and or if it was clean or had been contaminated. Can you see the problem here?
After further reading in another article that was quoted by another member it seems one of the problems that surfaced with ancient human DNA collection from dung was contamination. Do you not realize this?
The process they used to determine what was contaminated by the collection team and what was hopefully ancient human DNA to be collected from the ancient human dung, was to sample and test each team member separately.
Do you see where we're going here?
They didn't sample and test every modern human that had ever discovered the dung BEFORE their team collected the dung samples. For this reason the results could only be invalid.
I'm sorry but those are the facts. The study even revealed fox and coyote DNA, which led to completely unscientific speculations of "They might have eaten coyotes and foxes." or "A coyote or fox may have urinated on the dung at some point."
Hilarious. This reminded me of another DNA claim from 2008 and the GA Bigfoot body hoax. DNA tests came back as "opossum" where it was quickly suggested by the promoter of the hoax that "The Bigfoot may have eaten the opossum." Ridiculous for the same reasons, contamination. Since rubber suits don't have Bigfoot DNA the most likely event was that the DNA collected was simply from an opposum. Can you understand now?
When you say: "blood is a terrible source for DNA", you completely destroy YOUR credibility, not mine. Once again, blood is a great source for DNA sample collection. It used to be the ONLY sampled source testable for DNA genetic testing.
What we're beginning to see here is a panic among skeptics. Instead of acknowledging Dr Sykes as the professional he is, attacks on his character and scientific knowledge are beginning to surface. A bit premature in my opinion. As his results haven't been released yet.
This may lead to a problem later for those on the attack now. What if Dr Sykes ends up siding with the skeptical view? Does he then receive acknowledgement as the professional he is? But only if he agrees with the skeptic's position on Bigfoot? Ridiculous.
Will the footer's then claim, "You know you skeptics were right, Sykes is a kook." I think it'd be best to leave Dr Sykes' reputation out of the mud either way and concentrate on his findings when they become available. If you cannot agree he is one of, if not THE top in his field of DNA study, there's something seriously wrong with your perception of the man and of science in general.
