Ok, here´s my take on some of the "bearbigfootprints" presented by Meldrum at
http://www.isu.edu/~meldd/fxnlmorph.html, from where the pics were cropped.
(A)
(1) Rear foot imprint;
(2) Forward foot imprint, partially obscured by the later imprint of the rear foot;
(3) Mud splatered by the rear foot;
(4) Front foot claw marks, partilally obscured by mud splatter.
(B)
(5) Claw imprint (faint);
(6) Rear foot imprint;
(7) Forward foot imprint.
Cracks indicate the mud was probably partially dry when the bear walked over it.
(C)
(8) Claw marks, possibly created over very wet slippery mud.
Meldrum proposes the marks were created by bigfoot's fingers, when the forward part of the foot rotated about an axis (the mid-tarsal break). Anyone who played in the dirt or mud when he/she was a child will quickly understand why those most likely were not produced by fingers. Thrust your foot's fingers in mud. Rotate the foot backwards. Do the same with your hand's fingers. The results will nowhere be near what´s in the pic. What's in the pic can only be achieved by thrusting paralell narrow rigid blade-like objects (yeah, claws) in the mud. Just like a bear can do while walking on soft mud. Note that just below the arrow's point there's a divide, a change in thickness that may be where the claws join the fingers.
(D)
(9) This is supposed to be a "splattered finger", showing that the fingers are articulated and not just rigid wood carvings. Try moving your foot´s little finger to that position while walking... The result: OUCH!!!! But the footers will say that this is OK for bigfeet, since they have prehnsile feet. We'll touch this issue just a bit later.
(10) Check the position of this finger. Now look at the overall position of the fingers. Now compare this with the footprints at the bottom of the following pic, all taken as "bonna fide" bigfoot footprints:
One does not need to be an expert in anatomy, biology, primatology, etc. to see that FINGER MORPHOLOGY AND DISPOSITION DO NOT MATCH when we compare the feet (A), (B), (C) and (D) with the bigfoot footprints at the bottom of the pic!!!
Oh, yes, the "prehnsile feet" issue. The above pic also show some real prhensile feet, mid-tarsal breaks included. One does not need to be an expert in anatomy, biology, primatology, etc. to see that THERE IS NO MATCH BETWEEN THE REAL FEET WITH MID TARSAL BREAKS AND THE ALLEGED BIGFEET FOOTPRINTS!!!
Footers will then, as a last resort, appeal to Loren Coleman and his 9 species of unknown primates that live in North America (aquatic apes included), after of course, the standard complains about "close-minded scoffics", etc. etc. etc.
