Why not? We didn't have a clue that the appendix was useful until relatively recently.
I think its pretty funny how evolustionists still put humans at the top of the scale too...If you take that view, in function, we aren't...are we?

Yet, the appendix remains vestigial. It is diminished in size and function compared to its structure and function in organisms that depend on it.

And, while it has a function, the same function might be served equally well with something that was not an appendix... an extra length of intestine would serve.

The same question comes to mind, why does the human design borrow its structures from the design of other organisms (in which those structures perform a different or greater function)? Why does not the human design use structures uniquely designed to suit human needs?

Can you explain, in detail, why you imagine this is true? What is it that the appendix does? What is diminished about its function? Which organisms depend on it? What was it before it was an appendix? What animals have a fully functioning pre-appendix, what did it do, and how do you know it is the same organ as the appendix?
How could an extra length of intestine serve the same purpose as the appendix?
Why do we borrow design from a car in order to design a truck?

After reviewing the evidence, and I must correct my statements from earlier in this thread. The appendix is not demonstrably vestigial. Apparently it is possessed of lymphatic tissue that does impart a function that is important at some stage of life (whether or not that function is offset by risks of later infection), and does not appear to be degenarate relative to homologous structures in other organisms.

That would be a case of similar structure for similar function (in this case, so designed). Most of this thread discusses variant structures for similar function and similar structures for variant function, which is not predicted by design.

design cannot explain the shared homology of functionless DNA in humans and primates.

Jerry, are you saying that form doesn't follow function?
How about a radio and a voltmeter? Two different integrated circuits? Heck, you can even use the very same transistor in two or more different ways.
And you want variant structures for similar function? Tubes vs. transistors.

Plan 9 - Yes & no. Take a dolphin's fin. It's overall form follows its use as an adaptation for swimming. It's underlying structure depends on its evolutionary history. Look at a dolphin fin and then look at a swordfish fin. You will see that the swordfish fin is similar in structure to the fins of other teleost fish. You will see that the dolphin fin has all of the same bones as the human arm and hand, with the differences being in their porportional size.
Same when you look at a bird's wing, and a bat's wing. The bird's wing follows the structure of therapod front limbs. The bat's wing follows the structure of mammalian front limbs.
