We were talking vestigial organs. Or maybe you forgot?
And you have a one doctrine mind I guess. The Appendix is not a vestigial organ, it has an obvious function. For evolution to be true, vestigial organs should outnumber functional ones. To try and excuse the fau-pax of calling the appendix a vestigial organ by ignorant scientists, an argument is made that it is still vestigial but has become a different organ with a different function.
That clearly shows the inability to question authority or to think outside the box. One guy with 1930's science made an error. Get over it. The only evolution shown here is the argument defending Darwin's ignorance.
