    Some people, though very, very few and far between, are being born without appendix. Is this not proof of evolution? Do we need our appendix? Yes we once used it for something. Any Comments!?:bugeye:

    It is rarely that anyone reads the appendix of a book. But some times you do need it. Nature is highly conservative. So may be we need it for a specific situation that eludes the testing environment. May be it is a somekind of filtration mechanism. May be it is used during baby stage or in old age....it took a long time to figure out how the NO synthesis occurs in the body....

    What! This hamster’s appendix is gone! Fess up. Who took it? Nobody leaves until the hamster appendix is found.


    “Nature is highly conservative.”

    That statement could start an interesting discussion. This hamster does understand that systems that aren’t useful soon become dysfunctional. (Eyes in cave fish.) On the other hand “extra” or “useless” appendages may be “recruited” for new functions. A mutation that significantly altered a human appendix might not be life threatening and could lead to a new beneficial organ.

    Imahamster,

    It is interesting you mention this as I recently read a very interesting article in Scientific America that stated our ability to communicate verbally was most probably the result of a physical change in our larynx that occured for some other reason, but because the change gave us a wider vocal range, it was co-opted for the development of speach.

    I think this is one of the major roles that mutation plays in evolution. Just one small, insignificant-at-the-time change, while not impacting the species at first, may give rise to other capabilities that would never have been possible without that initial small change.

    Don't worry about your appendix being missing. Worry about the person who's appendix is there and performing some other function we don't yet know about.....

    Myna birds (sp?) can vocalize too. But did not develop speech yet after many million years. There may be more to it than a functioning organ....

    HEY....

    I've had multiple X-rays to my teeth when I was younger and now that I'm older....all show that I don't have wisdom teeth...never there and will never come out. Yes, it's a blessing...specially after hearing everyone say how awful it is to get them removed and all that jazz. I also didn't have my bottom front teeth (you know, the little ones in the middle bottom)....my dentist said it was probably something to do with evolution since we don't really use wisdom teeth.

    Well, but what about the middle bottom teeth.....we use those, don't we?
