== Human appendix ==
GodWarrior wrote in his last edit comment: "''Read references before adding them please, evidence in them is far from conclusive. The absolute nature of the statement is still far from justified.)''". I wonder if he has read the references. I'd like to know what is inconclusive about these:
* "The mucosa and submucosa of the appendix are dominated by lymphoid nodules, and its primary function is as an organ of the lymphatic system."
* "The appendix, in conjunction with other parts of the body which also contain cells called B-lymphocytes, manufactures several types of antibodies"
* "Although it used to be believed that the appendix had no function and was an evolutionary relic, this is no longer thought to be true. Its greatest importance is the immunological function it provides in the developing embryo, but it continues to function even in the adult … . The function of the appendix appears to be to expose circulating immune cells to antigens from the bacteria and other organisms living in your gut. That helps your immune system to tell friend from foe and stops it from launching damaging attacks on bacteria that happily co-exist with you."
* "it is now known to play a role in fetal immunity and in young adults. During the early years of development, the appendix functions as a “lymphoid organ”?, assisting with the maturation of B lymphocytes (a type of white blood cell) and in the production of immunoglobulin A antibodies [both of which help fight invading germs]. In addition, at around the 11th week of fetal development, endocrine (hormone-producing) cells appear in the appendix. These cells produce peptide hormones that control various biological mechanisms."
The second one can be read as being inconclusive, but was said in direct reply to a surgeon's claim that "it no longer serves a purpose in humans", and was preceded with the comment, "Your surgeon was a little out of date".
In case it needs to be said, only one of these quotes is from a creationist.
