Yet this is the same "scientist" who was sued for abrogating contracts for dog dna profiling as I understand it and couldn't courteously return a deer skull (thought to be something like a juvenile primate skull, go figure) to Tom Burnette upon request after supposed dna testing was done. Something very fishy about the lack of propriety I would say. Like you say, you are privy to some stuff too but I would imagine if it smells like rotten fish, it is probably rotten fish.1 point

I know. I'm sensitive about that h-word. Even the Pope calls me a hater. I knew that, too. But what I didn't know?: she had been an NFL cheerleader!1 point

Another reason why the human DNA is always too degraded is because they either have the tell you who that human is, or explain why they can’t tell you who it is……. https://www.icrc.org/en/doc/assets/files/other/icrc_002_4010.pdf1 point

7.62, you asked. This has been covered on this forum several times. Google the below title to visit a journal citation. It is good reading despite the age since the cameras that were tested are no longer in production. Camera Traps Can Be Heard and Seen by Animals smell color noise magnetic fields camouflage Smell. The plastic housings can absorb odors from storage / home. The mounting straps / security cables can have an odor. Python cables have a plastic covering. Plastics are made with flexibilizers or plasticizers. Plasticizers migrate out / off gas over time. Formic acid is a favorite of insects and bears. Noryl plastic and polypropylene do not absorb odors or moisture. Color of trail cameras is bad. We learned in WWII that color blind persons could detect enemy camouflage. Green is the worst because our man made green dyes can not match 'biological greens', especially near sunrise and sunset. Noise. Ultrasonic, sonic and infrasonic. Humans make ultrasonic noise when we breath and move. Wool and cotton clothes are quieter than synthetics when we walk. Trail cameras are emit obnoxious amounts of ultrasonic noise. Charging up capacitors for flash is loud. Bear boxes / security enclosures are reflector-projectors of ultrasonic noise. Plotwatchers emit a repetitious sequence of ultrasonic noise. Ungulates look at Plotwatchers when their image is captured. Shielding for ultrasonics can have a cost higher than the camera. However, the first Reconyx series called the 'Silent Image' was mounted in a 'Sea Horse' brand polypropylene case. 120 size I believe. That PP, about 1/4" thick did an amazing job of attenuating the ultrasonic noise. Sonic noise comes from the filter switching fixture when the camera shifts from daylight to infrared. As far as infrasonic noise is concerned, we are screwed. You can not attenuate infrasonics. ELF, X ELF is how Navy's communicate with their subs---- through the earth. Magnetic fields. Trail cams have switching, regulated power supplies. They have fluctuating AC and DC magnetic fields. The area of the batteries is enjoyed by ants and spiders. The color and texture of plastic housings can be dealt with. ASAT fabrics, Cambush and something we don't see much of in the US, Camohide from South Africa. The previously mentioned camo items do not reflect UV. ASAT 3D leafy fabric changes color and texture. Cambush does the same. Camohide was not developed for 'wild' animals. It was developed to hide cameras from human animals, poachers. It is 3 dimensional, has good texture and color options. Worth a look just to see what is out there. Paint your own with the DIY option. I bought the 'pine' bark. It does have a 'synthetic' smell even after being outside for a month. Less than $30 and the shipping is high. DHL out of South Africa is the fastest. The philosophy of the Camohide people is that bark pattern is second to color. Cameras are not easy to deal with. I am reminded of a forum member who stays anonymous. He placed several trail cameras on trees. When he returned to the location, the trees had been pushed over to the ground, camera side to terrain.1 point

This is simply not true. There is a reality. And Melba Ketchum tried to pass off her work AS reality!!! Science isn’t being unscientific by questioning her work. It’s absolutely doing its job! I don’t understand this mindset. If I went to Africa and I was a vet with some knowledge on genetics and I came back with a bunch of DNA samples, tested them and then wrote a paper (in my own peer reviewed journal) that proclaimed a new novel species? And the rest of science looks at my work and says….ummmm no. So I get mad and post pictures of a Star Wars character as some sort of buttressing proof!? How is science at fault here? Dear God people if you’re going to support primatologists and DNA sampling? Pick someone, ANYONE with a proven track record! Hey look! Dr. Mayor is holding up a REAL type specimen of a novel primate species! 🤯 That’s not EGO….that’s science. It’s why my pot pie comes out of the microwave hot. It’s why I can Bluetooth my phone to my TV and watch you tube videos. It’s why we know we share 98.9% DNA with a Chimpanzee. Despite my advocacy of Sasquatch being a real creature? I’m not going to cheat and move the goal posts of discovery to fit my world view. And I am NOT going to allow my feelings or pocketbook be manipulated by snake oil salesmen.1 point

Continuing.... Metabarcoding inthe lab picks up the genus of everything that visits or is currently living is an environment. Everything. Dr. Mayor's did. But she also got genus Pan troglodyte (Chimp) DNA, and, more than likely Human DNA as well. What did Dr. Melderum get. Everything also. With one exception: Human DNA that was apparently too degraded to show maybe Pan troglodyte or some other primate? Both of which are different of a different genus. But nope, same kind of environment with regards to rainfall. And again samples from soil. In Dr. Meldrums case the soils was even more protected from UV rays because the soil was under the nest structures but perfectly capable of showing an organisms genus. How do I know? Because the genus of all the animals that had visited or lived close by turned up in the results. But only ONE was apparently too degraded to show anything other than Human. But t did show genus Homo (Human), right? And the genus of everything else showed up as well. DNA sequencing at that time was very precise and since the announcements by Dr. Meldrum and Dr. Disotell came at about the same time in the Fall of 2018, only about for years ago, those announcements came soon after the lab sequencing and results were known. Science had already been using environmental DNA sequencing for a couple of decades before those announcements were made to identify an animal's genus in the wild. It was not a new science by any means by the time those soil samples were collected and tested. Dr. Mayor's in 2020 and Drs. Meldrum and Disotell's in 2017 or 2018. So, all being equal where environment, rainfall, professional collection and sequencing protocols, are in line, what gives with one getting a non-Human genus in it sample and the other not? The Human genome is the gold standard, the reference that is used in which all other DNA sequences are compared to. It is the base line and is constantly being refined as more and more Human genomes get factored in to improve it as a reference genome. The smallest DNA molecule is the mitochondrial but it can have hundreds of copies of itself inside a single cell. And though small, it STILL contains over 16,500 (16,569 to be exact) amino acid pairs. How many, out of those 16,569 amino acid pairs, are needed to determine genus match? Less than 50. Sometimes even only 20. Ideally an unbroken sequence of 150 pairs is ideal and considered a good quality sample. For determining genus that's all it would take. Good enough for Dr. Mayor Kentucky samples submitted to the lab at the University of California. But somehow Dr. Meldrum's from Mason County was too degraded for Dr. Disotell's state-of-the-art lab at the time at NYU? He was, and still is after all, an expert in evolutionary primate genetics, though he has since relocated to UMass Anherst in the fall of 2019. Now I'm no DNA expert but I AM a logician and this one loose end has never made any sense to me whatsoever. Why doesn't it make sense? Because no one knows how long Dr. Mayor's large wood structure was there in eastern Kentucky. And no one knows how long that Chimp DNA was there either. But one thing is certain, the nest structures in Mason county were fresh constructs. Vertical stems were pushed into the ground. All the material for the nests were harvested close by and woven into those nests. So regardless of the soil under the centers of them, there should have been DNA left all over the place there: Under and around these structures on the ground, on the ground in the huckleberry patches and on the stems. DNA should have been just about anywhere that could have been sampled. So what happened? No one thought of that? DNA is pretty tough stuff. It's not going to go away or completely degrade after only a few weeks or months. Everything I've said so far in these first three posts is all scientific FACT, along other information as it was reported by the parties involved in these discoveries. Fact, Sasquatch DNA won't be Homo Sapien DNA that is closer than Neanderthal or Denisovan or any other recent Human cousin. It's DNA MAY be Homo but it would be so far removed genetically that there would be no chance of mistaking it. In other words, it would have so many mutations as to be unrecognizable as Modern Human no matter how degraded. No one can tell me that out of 16,569 amino acids that none of it would show non-Human mutations. It borders on the ridiculous to think otherwise. The ONLY conclusion that one can arrive at that makes any sense is that Sasquatches did NOT build those structures. But all the manually broken stems of the huckleberry bushes suggests that it wasn't Humans. But if it wasn't Humans then someone is covering up the fact that there must have been Non-Human primate DNA at that Mason county site. The point is, there is no way, when all other animal genera were there, that only Human DNA was found to be degraded, at a site with every chance possible to have DNA fresh enough to show a non-Human primate was present. There. Done. Does anyone agree or disagree with this assessment?1 point
