CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

It is so mechanical digestion can occur followed by chemical digestion. If food went directly into your stomach you would be in a world of hurt. The teeth are actually part of the digestive system (one of the 11 major body systems).

As queasy as my stomach has been yo uwould have to bring that up? LOLJet Black said:
Yes, chemical digestion outside the body, first-nice and efficient.

I agree with this. Food entering the stomach directly from the stomach would require a much stronger digestive system and a painful excretionary process. I suppose the mouth could have been on the hand, but that would make the arm complex and weaker in a way. Same with the leg. The butt would make it impossible to see what your eating. The mouth being at the opening where the wind comes in is actually the most efficient place. It is somewhere that is a distance from the stomach, and something that the hands can manipulate food in front of easily. You may choke every once in a while, but that's your fault. Utilize those teeth as much as you have to, and don't breath when there's food in the back of your mouth.LorentzHA said:

It would be more efficient to have wide nostrils, and allowing breath only through them. No choking, but all the benefits. I beleive the cheetah has this kind of system.

I was under the impression that non-baby humans are unique in this respect. All other mammals can eat/ drink and breathe at the same time (as can new born humans) as the larynx is high up in the throat, so air and food do not mix. After about 6 months, a human's larynx "moves down" the throat to facilitate speech and we can no longer do the two together.Data said:

Ive heard rabbits have to eat their own **** because of a poor quality digestive system. My theory is that the "serpent" in the Garden of Eden, was acually a rabbit, and God cursed the rabbit. Because I would rather crawl on my belly and eat dirt, that have to eat predigested food to survive.

"having a mouth in your head, (and a crossing windpipe and foodpipe) is indicative of either an idiot designer, or a blind process which just selects for whatever happens to be the most successful at the time."
People choke on food.
"the shape of the appendix"
It gets infected very very easily, due to its shape.
"the coccyx, the extensor coccyxis"
Yup. There is a muscle to move the tail bone. But the tail bone is fused and solid. Pointless.

vertebral discs, and why they are bad design, showing they either evolved or were the work of an incompetent designer:
The vertebral discs do not handle continous compression well. In quadrupeds, this isn't a problem as the spine doesn't carry the upper body mass. In humans they do. Further, due to the arrangement of the discs in relation to the spinal nerve, a failure of the disc (due to excess compression), will release the pulpus nucleosis, which compresses a spinal nerve, leading to severe back pain.
A sensible designer would have enlarged the facets of the zygopophyses, in order to put load-bearing discs there. Further a change to the neural arches would have ensured that rupture would not result in pressure being applied to the nerve. Finally, routing blood vessels through hyaline cartilage would allow the tissue to regenerate after damage.
If you want to believe in classic design (rather than design through evolution, then ID means Incompetent Design.

Yes you make some excellent points, but I still see an intelligent design behind it all (however I am not proposing it is the Christian God). There are definately areas that could use improvement. You make a great point with respect to hyaline cartilage. Also I think cardiac tissue and neural tissue could use a better regenerative process because as of now if either of these tissue types like hyaline cart. gets damaged there is not much that can be done since neural and cardiace tissue differentiated and specialized-regen would have been a nice feature however!!Gormless said:

There is a reason for every part in the body some things just appear pointless at this time because evolution has done away with several features of Homo sapien.Data said:
As far as the appendix goes, you are right it does become infected way too easily. At one time in our past it helped our ancient relatives to digest bark. It is at the end of the accending part of the large intestine which would make perfect sense, but it is not used this way anymore so not it is a nuisance, however, surgeons do not mind too much
Yes the Extensor Coccyx is now pointless but was not always. The coccyx was not always fused either that is why the extensor coccyx is still there it is vestigial but I suspect it will eventually dissapear if the human race is able to keep going on this planet.
