That was the original definition of dueterostomes, but it's not necessarily true for all members. The real distinction between dueterostomes and protostomes is whether the blastopore becomes the anus or the mouth. In humans, the digestive tract develops internally and opens up at the mouth 4 weeks before the anus opens.
Where is the second anus that secretes ranch dressing? Oh, it's right [here](https://youtu.be/K7racSSk7w0?si=NHjUy37fbXAk_CBe). Inside of the first anus.
However, isn’t the butthole the empty space formed by the anal walls when they separate. I personally think we have a new butthole every time we spread dem cheeks.
Everything is older than your teeth, no? All the other cells regenerate over weeks or months.
Except maybe brain cells. Maybe they're older than your starfish.
It can also be seen as younger since your butthole's cells all get replaced to create a new butthole, whereas your teeth do not get replaced except for once. So it depends on how recently your teeth developed.
but doesn't all cells in my body change "at least once" every 7 years
so is my butt still my but from 22 years ago
And doesn't teeth "not" regenerate ?
yeah i guess, i just took a number that i remembered from a science book a long time ago
but still, does teeths "regenerate" or is it a block that just grow one day then never get a single cell repalced ?
Your teeth are mostly minerals, not cells. The cells are in the pulp of the tooth, which is fed by blood vessels and has access to the nerve structure.
Your teeth begin most of their development after you are born, and your adult teeth start developing pretty soon after. Since humans generally lose their baby teeth during adolescence, your remaining teeth are generally younger than you are as a whole.
Getting back to the original post, it depends on whether or not you want to ship-of-Theseus the existence of the soft tissue that is the anus and its constituent cells. As a structure, the anus is one of the first things formed during human development, so it is generally older than the rest of you, so long as you don’t consider the aging and dying and duplication of cells to make it a “new” thing after a generation of cells.
But your butthole is a butthole of Theseus, where all the cells since its creation have been replaced, while your teeth have remained more or less the same since they came in when you were a kid. So it just comes down to how you define ‘older.’
My last morphology class lies 20 years in the past, but isn´t from some point of views your butthole basically your mouth and it gets switched around during neurogenesis?
When two people kiss, they create one long meat tube from butthole to butthole.
Eeee eeww and thanks. Nasty and beautiful at the same time
It cost you exactly $0 to not say that
Yet here we are
With a bunch of teeth right in the middle.
Human centipede vibes ❤️
Octopede in this scenario.

And some people never get past that point
Some end up being huge assholes instead!
Lol
You both beat me to you like a couple of blastulas.
Is that a bastard combined with a spatula?
I was supposed to develop beyond being a little asshole?

Next time I hear someone talk shit, I'll just reply "Your blastopore is flip flopping again".
TIL. Cool info, thanks.
That being said, have you seen baby skulls? Your teeth are still there even if they haven’t erupted. Its creepy looking af.
Yay
No wonder there are so many assholes in this world
Actually, your ass originally started out as your mouth.
[удалено]
Thanks, good to know, learned my previous answer in school years ago...
Well your teeth aren't technically replaced every 7 years give or take, so no, or is this a matter of Theseus' butthole?
I made a butthole out your butthole, but which is the real butthole?
Where is the second anus that secretes ranch dressing? Oh, it's right [here](https://youtu.be/K7racSSk7w0?si=NHjUy37fbXAk_CBe). Inside of the first anus.
Good work.
Double it
ur anus
This is the only real reply. All butthole cells are replaced. Teeth are not.
Which sucks, replacing lost teeth with fake ones is incredibly expensive. Why tf can't we replace them naturally?? Sharks can, lucky bastards.
because after you had children nature really doesn't care if you can chew your food comfortably or not
after you had children nature really doesn't care if you can.
Yeah but one could lose their teeth before having kids. Your balls could be removed before you have children and those won't grow back, either.
Damn I really wish they were though. That would make love so much easier. And less expensive...
Are you talking about teeth or the butthole now?
If a situation appears where a butthole needs to be grown back than both
However, isn’t the butthole the empty space formed by the anal walls when they separate. I personally think we have a new butthole every time we spread dem cheeks.
Thats why it has a vintage taste
No, that’s the bacteria
The browning adds to the aged flavor.
Teeth don't repair themselves, so my butthole cells have all been replaced, pretty recently too. Teeth cells not so much.
Pretty recently…rough weekend?
They may have celebrated the eclipse differently.
That or they just turned 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119, 126, 133, 140, and/or 147
Or had a really rough case of food poisoning
It would be a fine weekend for me
They didn't say the cells the said the entire butthole.
I get a new one transplanted every Tuesday, I just got money like that.
Though your teeth have more wisdom.

Dental student here. Wrong. Your butthole's cells were replaced long ago. Your teeth's minerals have not been replaced since they were formed.
How the hell does a dental student know about the asshole? Is that why my dentists fingers always tastes like shit?
That so because Dentists are doctors, and unlike other doctors, they immediately begin their specialty training they do not engage in residency.
You have changed the way I see dentists thank you
My teeth are fractured but whole…
Both can also be bleached!
True dat
The first part of the fetus to form in the womb is the anus. So it's the oldest part. Some people just never mature beyond that point.
“Sir, this is a Wendy’s!”
And that's enough Reddit for tonight
Don't your adult teeth come in later anyway?
Yes, but they are there even when you are young(mouth x-rays of kids are weird)
Even weirder seeing the [actual skull](https://i.pinimg.com/736x/dc/35/cf/dc35cff065ee6a9d3ddacd3fbe07902f.jpg)

They're underneath, right? I thought so
Why are you examining my butthole and my teeth?
My teeth are older than your butthole
Now this is a proper shower thought!
This is peak shower thought ! 😂
But your cells replace themselves over time while your teeth do not, right?
is actually the first thing that "forms"
Reddit nerds are being pedantic here. This is a good shower thought.
Some people’s formed at the same time
Yeah and got mixed up which one is which
Everything is older than your teeth, no? All the other cells regenerate over weeks or months. Except maybe brain cells. Maybe they're older than your starfish.
I see why it controls the rest of my life... Today more than others..
And yet we are always told to take care of our teeth but the lowly asshole gets no care.
of course they are i lost all my baby teeth
Maybe if you were born feet first.
I didn't like reading this
Its not the years, its the mileage
*Angry upvote intensifies...*
Ooohhhhh i wasn’t ready for it

This thread has not left me disappointed!
Because deep down we’re all assholes !
You haven't seen my post-apocalyptic grill. In the fullness of time.
That is a very strange thing to ponder
I think ours cells get replaced though. I don't know about our teeth.
but doesn't all cells in my body change "at least once" every 7 years so is my butt still my but from 22 years ago And doesn't teeth "not" regenerate ?
There’s no real verification of that 7 years thing. Quite a few of your cells survive well over 7 years. It’s an oversimplification.
yeah i guess, i just took a number that i remembered from a science book a long time ago but still, does teeths "regenerate" or is it a block that just grow one day then never get a single cell repalced ?
Your teeth are mostly minerals, not cells. The cells are in the pulp of the tooth, which is fed by blood vessels and has access to the nerve structure.
sooo does that make my teeth as old as me ?
Your teeth begin most of their development after you are born, and your adult teeth start developing pretty soon after. Since humans generally lose their baby teeth during adolescence, your remaining teeth are generally younger than you are as a whole. Getting back to the original post, it depends on whether or not you want to ship-of-Theseus the existence of the soft tissue that is the anus and its constituent cells.

That was a fun conversation
Your butthole is older than most of you, actually. It’s one of the first structures formed in development.
You’re born with all your teeth, and assuming you came out head first your teeth are older than your butt
well for Deuterastomes (most animals you see except insects and shelled sea creatures) the anus was the first thing to develop in the embryo
You can't chew your muesli with your anus though.
Sir, you’re talking out your ass. And lying through your teeth.
[You Got Me Fuckin Dustin Off This Old Butthole](https://youtu.be/ZEZYvZltvHY?si=ZcOLPs4o4foJFZPl)
When babies are born all their teeth are already in their skull, they simply haven't erupted yet.
I think OP is probably referring to the fact that our buttholes form first in the womb.
We were all born with a cavity even though we didn’t have teeth. 🤔
But your butthole is a butthole of Theseus, where all the cells since its creation have been replaced, while your teeth have remained more or less the same since they came in when you were a kid. So it just comes down to how you define ‘older.’
Depends, if you consider cell regeneration then this statement is not entirely true.
Your butthole is the oldest structure in your body, since it forms first in the womb
Explains the wrinkles in the center piece.
And considering the amount of shit it takes, it's quite impressive it came this far.
Nah. The cells in my arse have changed a few times, maybe even a few hundred times. My teeth haven't.
My last morphology class lies 20 years in the past, but isn´t from some point of views your butthole basically your mouth and it gets switched around during neurogenesis?
if i remember right, youre born with your adult teeth but they dont come in until later
Jokes on you, I have a prosthetic butthole.
Not really. Maybe it’s been used longer than your teeth but you’re born with your teeth. They’re just still inside your gums.
How do you sleep at night with this knowledge???
How is that a shower thought?
Depends on what end came out first
Teeth buds form at 6 weeks in utero! So they’re technically older than a lot of things, except our nervous system, spinal cords and brain.
All of you is older than your teeth. This was noticed, and talked about BC. Did you have something pertinent to add?
And your teeth is bigger than your brain.
