I'm also very interested in the biological implications of all this, but I have a few questions and comments. Firstly, I'm curious about how many physicians or other experts in biology are called in these occurrences. I appreciate that people in law enforcement have experience with crime scenes and bodies, etc...but interpreting effects on the human body takes a lot more specialized knowledge. As per my background, my undergrad degree is in Biochemistry and Molecular Biology and I'm in the process of applying to graduate programs in Tissue Engineering. At one time I had wanted to go to medical school so I've spent a fair amount of time shadowing surgeons and observing procedures, that having been said:
People comment on how difficult it is to remove organs through small incisions. That really is not the case. I've seen several laproscopic surgeries in which two small incisions are made to insert the tools used by the surgeons. In this manner a gall bladder (admittedly not a large organ) can be removed in a minimally invasive manner. Organs compress and skin/muscle/etc. can stretch. It's fair to assume that humans who have the motivation and the resources to perform a mutilation are capable of doing the damage observed.
As for DNA sampling of humans and other species, sampling is as simple as collecting hairs or swabbing the inside of the cheek. There is no reason whatsoever that one would have to kill or take apart an organism in order to get a hold of its DNA.
If the matter is farming us for spare parts, this seems incredibly unlikely for several reasons. First of all, it is a big stretch to assume that beings from another planet or dimension would even be able to interact usefully with our tissues. Transplanting organs between humans is extremely difficult due to immune responses rejecting the organ as foreign. For that very reason research is directed towards being able to develop tissues unique to individuals at some point in the future. Any being capable of traveling to this planet or from another dimension would have to have a level of technology sufficient to overcome such hurdles in their own biological sciences. Aside from the problems of tissue compatibility, we have to wonder if their biology is similar enough to ours for them to even consider using us a resource. We may be so completely different that there is absolutely no use.
That's my little science geek rant, but bearing that information in mind, I can't help but think that mutilations are directed by more earthly forces, especially given evidence such as eyewitnesses to helicopters or scavengers. I really enjoy the Paracast, but Witkowski seems like another guest who has a lot more stories than evidence. We all want to know what's happening, but wild speculation isn't going to get us there.
