Yes, yes, reading is a good thing.
Please read the following link, with a snippet to wet the appetite:
Another pouch, thought to be vestigal, by evolutionists UNTIL JUST RECENTLY (emphasis mine), becomes a gland that assists in calcium balance."

Changing the subject already? Probably a good move - the last topic didn't look good for you.
The page you linked to is a great compendium of creationist misconceptions about what evolution is.
The specific example of vestigial is a great case in point. Vestigial does NOT meant that the organ/structure has no function now. It means that the organ/structure is doing something other than what it was originally designed for. This has been known since Darwin.
Just because you find a function for a structure (the appendix, for instance) does NOT meant the structure is not a vestige of an earlier structure that had a different function (in this case, the appendix was used to help digest cellulose in our ancestors.)
