Default Evolution Of The Human Appendix: A Biological 'Remnant' No More

Evolution Of The Human Appendix: A Biological 'Remnant' No More

ScienceDaily (Aug. 21, 2009) — The lowly appendix, long-regarded as a useless evolutionary artifact, won newfound respect two years ago when researchers at Duke University Medical Center proposed that it actually serves a critical function. The appendix, they said, is a safe haven where good bacteria could hang out until they were needed to repopulate the gut after a nasty case of diarrhea, for example.

Now, some of those same researchers are back, reporting on the first-ever study of the appendix through the ages. Writing in the Journal of Evolutionary Biology, Duke scientists and collaborators from the University of Arizona and Arizona State University conclude that Charles Darwin was wrong: The appendix is a whole lot more than an evolutionary remnant. Not only does it appear in nature much more frequently than previously acknowledged, but it has been around much longer than anyone had suspected.

"Maybe it's time to correct the textbooks," says William Parker, Ph.D., assistant professor of surgical sciences at Duke and the senior author of the study. "Many biology texts today still refer to the appendix as a 'vestigial organ.'"

Using a modern approach to evolutionary biology called cladistics, which utilizes genetic information in combination with a variety of other data to evaluate biological relationships that emerge over the ages, Parker and colleagues found that the appendix has evolved at least twice, once among Australian marsupials and another time among rats, lemmings and other rodents, selected primates and humans. "We also figure that the appendix has been around for at least 80 million years, much longer than we would estimate if Darwin's ideas about the appendix were correct."

Very happy to find this thread and link from Kassy.

I am now 4 days out from having my gangrenous appendix removed.

Has been the most painful and miserable few days of my life.

Seem to be recovering okay. On my next visit to out patients I will explain in robust detail the purpose of the appendix.

Now I appreciate and understand why I've not suffered too much from tummy bugs in my 77 years.

The nurses in the hospital thought the appendix was a redundant organ. Sheeeesh!

Don't worry Bob. I had my gall bladder out and all they did was make three small holes and they were small enough to be covered by bandaids. I felt great the next day, a little sore but no more pain from it.

Hah! When they found gangrene they made a LOT of little holes, even through my belly button! Because of the enlarged appendix they had to make a longish cut through the stomach muscle. They had to wash every thing with saline solution and put in a drain. The op was a week ago today, there are wire clips in the main incision which are due out on Monday morning. I am still sore.

Are they pumping you full of heavy-duty antibiotics, Bob? Mine burst as they took it out. I have an 8-inch scar on my belly where they had to open me up to clean everything out.

Ow indeed! I was very lucky. Appendix had not burst but was enlarged. Looks like I will only have a 4-inch scar.

Was on antibiotic drip in hospital. They gave me three days of pills to take home. Dressing change three days ago showed all was well. As I said above wire clips due out Monday.

All internal pain seems to be gone, just surgical pain. No problem if I move carefully and don't cough!

I know what you have been through Mama. Will raise a big toast when I get the final all clear.

That was only the half of it, Bob! I spent 10 days in the hospital. This was 36 years ago, and I had a toddler and a 5-month-old nursing baby at home. A baby who REFUSED to take a bottle. DH told me later that he and the neighbor lady who was helping him managed to get one bottle a day down her. Poor kid.

I had gangrene started in my gall bladder. They had to enlarge the incision to get it out. Very lucky for me it didn't burst. It was a small miracle the thing didn't burst. My doc was fried that I put it off for so long.

Hang in there Bob. It will get better with some more time.

Wow! I have a 36 year old daughter who used to scream bloody blue murder from colic during her first few weeks until we learned about soya milk. She was fine after that. Very fine lady now.

Okay! Wire clips are out! ALL 25 OF THEM!!!! Couple of OUCHERS.

Nurse says all looks well. Treat skin gently for a while yet.

Kassy's post linked to info that the appendix is more important than we realise.

The report mentions that people who still have their appendix recover faster from stomach upsets than people who have lost their appendix.

Not found a good explanation for this yet but personal health is now paramount in the twilight years and wondering if I should do anything to keep the old gut bugs happy. Will post if I find anything positive.

I read an article that postulates that the appendix is a reservoir for your bacteria/virii patrimonium. The microfauna present in your appendix can recolonise the gut after an apocalyptic event.
It sounds plausible but it is still a theory.

It would probably be helpful for you to use probiotics and yoghurt to seed your intestines during and after diarrhoeal episodes.

Alternatively, there is now a medical intervention whereby faeces from someone is transfused into another person's intestine for the same purpose of recolonisation.

The choice is yours !

No point to make, I just really like the phrase "virii patrimonium". Cool neologism, if a bit of a historical linguistic anachronism.

Sorry I'm late to this thread, Builder Bob!

Sorry you had such a nasty and painful start tp the year!

Glad you're mending well and definitely want that to continue!

>>>Warning:

There's a funny thread about Hull in the Lounge.

Wait a few days to read it and then only do so with a pillow over your mid section, to keep it from hurting when you laugh
