Argh. There was no sabotage and minimal contamination.
There was deliberate lying by Ketchum. The people in her "camp" were under NDA but information was leaking. She told different lies to different people to see which ones became public as a means to identify and plug the leaks. It worked, however, it had farther reaching consequences than she planned for when the lies took on lives of their own rather than ending when she corked the leaks. "oops."
The handling of the samples was good. Cleanup was effective. There was no contamination to speak of. What there was was sample degradation. Many of the samples were older and had been exposed to the environment for extended periods of time causing them to break down. There was also a flaw in the extraction / replication / sequencing methodology chosen. Taken together, those produced comparatively short DNA segments that had to be reassembled (by computer) for comparison ... this was done badly. This is where the apparent weird DNA popped up. It was not real, it was computer-generated during sequencing because the assumptions made in the "next gen" sequencing process were too optimistic.
There were plenty of red flags for a careful researcher willing to see them. Melba reported 109 of 109 samples testing positive for bigfoot. Not possible since a hunk of Justin's bear was included. That's why she asked him to soak it in bleach to destroy the rest ... confirmation of what it really was contradicted the claims she was making. I do, however, believe there were real bigfoot samples within the pool that was tested.
Melba was trying to force the data to support a pre-determined conclusion rather than letting the data lead and following where it went. Plain and simple in hindsight.
Ya'll ought to know this if you've read the Ketchum threads, followed the analysis, and listened to the youtube vids. I'm kind of disappointed that you've gone this far into the conversation without paying attention to what has already been shown.
