Relative to the find of a finger bone of unknown origin without strata or anything to date it as old, it may be tested for DNA but only if they think it was there as the result of a crime. However States in the PNW have literally hundreds of samples of DNA linked to crime that have yet to be tested. Rape kits. The reason given for lack of testing is money. In the case of Kennewick man the test would show he was human, because he was. His bone morphology showed that he was human. No one would likely carry that any further with carbon dating unless something like the arrow head or strata indicated the skeleton might be ancient. The reason being, according to a University of Oregon PHD, a carbon dating test costs over $800 dollars. Based on what we have seen with BF related to DNA testing, I would bet money that if a found finger was tested at all, it would be interpreted as contaminated human. Should it test out as some kind of ape, the question would be how it got there, not proof of existence of BF. .
The problem for me with DNA testing, is that it seems just as hard to get a DNA sample to test as it is to get a BF on a lab table. Anything other than DNA viable tissue is not likely to result in viable DNA to test. Hair hasn't, blood has yet to be collected, and testing objects BF have supposedly touched, nothing has yielded a positive test. Of the options getting materials to test, shooting one, find one hit by a logging truck, or find find one killed by a natural calamity, only shooting one seems to be in the control of humans to achieve. And in spite of people trying, that has not produced a body yet. At this point in time with my research area gone inactive, I would have no idea where to even go to collect E-DNA. Others may have contact, but for whatever reason, are not trying to collect DNA. Cost, lack of knowledge about how to do it, or not knowing where to do it are likely reasons. Testing hair seems to be a dead end, testing scat is a race against time and bacterial degradation. and BF seem to collect their dead. While DNA testing sounds like a easy thing to do, in actuality it is not.
