Vid, your perspective on why it is termed junk is out of context.
I remember the first time I saw the left recurrent laryngeal nerve. Nerves simply conduct a charge. Because of how we evolved from a fish history, our nerve passes its end point and wraps under the aorta (blood vessel from the heart) and then goes back up to where it is supposed to go. It is 11 inches longer than it needs to be. It would be ridiculous to claim it was designed, we can see from evolution exactly why it follows an illogical silly path.
When I mentioned this to JW family and pals etc at the time, they all without hesitation said we obviously dont yet understand why it is that longand in the future scientists may just find out.....
This backward, ignorant thinking, would be harmful to progress and science, but thankfully we don't think like that.
As for your appendix.......facepalm and sigh.
