It is the only plausible scenario that explains the repetitive results...how many DNA samples could you reasonably expect to be "contaminated" with H. sapien DNA? Okay, more than one is likely, several is possible, but it seems like we are seeing this EVERY time results are published. I've suggested before...the lab reaches a point where they are satisfied the sequence contains DNA markers that agree with known human sequences and they shut it down, write it up as "contaminated" and move on. Unless and until those samples are fully sequenced and a library of them is kept for cross referencing, we may continue to overlook subtle variations in the genome that indicate a Sasquatch. This, of course, means time and money.
Moreover, although the behaviors of Sasquatch can be viewed as ape-like, so can many of ours, if we are truthful about it...they just exist within a framework of a hyper-socialized, densely populated and technologically saturated environment. If you also believe the close-up observations and "gut" feelings of those who have lived in close proximity to BF, almost unanimously they come down on the side of "people". These observations count.
