I misspoke on the Pancreas, forgive that error. It'll happen when its 15 against one.
But how can we survive without an Appendix, if it is so vital?
And why do whales have feet?
We can survive without arms, legs, eyes, ears, gall bladder, all manner of organs that are useful and make life a lot easier and more pleasant. Who ever said the appendix was that vital? Or wisdom teeth? Other animals have better eyes than ours. So what? So what's the point? Is that supposed to be argument against ID?
Is just surviving enough? Or do you want to be healthy?
People without an appendix have a much higher probability of intestinal disorders. The appendix maintains a bacterial culture to insure proper digestion. This has actually been known for a long time; the talk of the "useless" appendix is just idle school teacher tails.
whales don't have feet,some have a tiny bone that is a an anchor for mussels, it has no joints. this bone as a 'vestigal leg' is an interpretation with evolution assumed from the get go. still serves important functions with out being assumed a degraded functional leg.
Easy!
