I'm curious what knowledge a new graduate with a degree in biology would have that has relevance to bigfoot? A degree with just the title 'Biology' is going to entail mostly molecular and cellular biology, so what does that have to do with bigfoot? Because they're made of biology? They're also made of chemistry, and physics, so are chemists and physicists equally at an advantage when viewing a sasquatch while hiking in the woods? Does my advanced degree in bioengineering give me an upper hand?
You can argue for my advantage if you want, but I'll tell you: "of course it doesn't." It has given me a view of what practicing research scientists can be like and how they think, though. Many of them are not particularly great problem solvers. They know how to make their work look sexy on a grant. They come to me when their MS Word freezes. They shout "I HAVE A PEE AICH DEE!" when they find they can't win an argument (well, at least one particular French post-doc does).
Look I don't mean to pan the whole scientific community just because I have the misfortune to work with some idiot-scientists at the moment, obviously there are many brilliant minds at work, but they (and I know this has been said a thousand times already but here's one more) are not thinking about bigfoot. Even if I were to allow that we were talking about someone with a new degree in Wildlife Biology (does anyone even offer that to an undergrad?), they would still only really have relevant knowledge if they had a particular focus in apes, and if they'd done field work. George Schaller, Dian Fosey, Jane Goodall. One is gone, the other two advocate for bigfoot study, imagine that.
I'll use this post as a testing ground for an idea that's been kicking around my head for a while, but don't have much practice articulating yet, here goes: 'Bigfootology' will never be a scientific discipline. Sasquatch will never bend to the scientific method, we will not 'prove' their existence scientifically. The basic overarching reason for this is the impossibility of control over conditions. In order to confidently reject a null hypothesis, we need to be able to set up experiments that have clear outputs for a given set of inputs, that allow for deduction of the mechanism by which the output was produced given our setup. No such experiment is possible when interacting with bigfoot any more than it's possible when interacting with humans; the intelligence of these beings precludes it. Control of experimental conditions in their woods is completely theirs, and we are their willing lab rats.
I do think Meldrum's career path highlights a valiant effort at solving this riddle. He pursued an area of study that gives him expertise in the one type of physical evidence in bountiful abundance, and has made great efforts in showing how a huge variety of aspects of footprint casts could only be produced by an unknown hominid - but ultimately, the clarity of the work falls short of overcoming entrenched biases. It's not sexy enough.
IMHO, 'Proof' will come about gradually as a snowball of more and more people being led to the aggregate evidence, being taught how to think about it, and getting out in the woods confirming it for themselves. The only possible exceptions are DNA, video, or a body. The former is very murky water, and the latter two are lightning-striking-your-winning-lotto-ticket odds.
