How can nobody in the world know what it does? Do you know what everybody in the world knows? And why would it be a guestimate if they didnt guess or estimate anything? Its the Duke University, im pretty sure they know what they are doing. Its not like someone who goes to college says "hey, maybe this thing does this" and goes out and publishes it, there IS research and expirementation involved in studies you know. And you dont need to watch something to know what it does, we know our brain thinks but we cant just open someones head and watch them think. Oh and BTW it is connected to the intestines, the cecum is a part of the large intestine.

if you ever happened to look at a picture of the appendix you would know it in fact IS connected to your large intestine and last time I checked your intestines are pretty important. You may be a smart 12 year old but maybe you should know where something is before you say it isn't connected to anything important.

I was told years ago from my great grandfather who was a farmer that the appendix was for collecting seeds from fruit. He said man was never intended to eat meat just fruits. I'm not saying it's true that's just what I was told. However I have done research on this and many claim this to be true.

Well ur wrong the appendix is connected to the large intestine like said in the artical that u should of read all of it -.-

if you really are a smart 12 year old, you would know it's the gall bladder... a gull bladder is something a bird uses to pee... i also like the fact a smart 12 year old thinks he knows everything and that scientists and researchers know nothing. well done!
