Tbf, our teeth aren’t bad. They just didn’t evolve to consume so much sugar.

Bro, eating oranges puts our tooth enamel in a weakened state. If we were designed, it was by an idiot.
Hawke@lemmy.world 2 years ago
finitebanjo@lemmy.world 2 years ago
Actually a bigger contributor is underdeveloped jaws due to no longer requiring to chew from.a very young age for nutritional requirements.
db0@lemmy.dbzer0.com 2 years ago
Why would stronger Jaws prevent teeth decay?
kittehx@lemmy.blahaj.zone 2 years ago
Half our expected lifetime was our expected lifetime back when they evolved. Teeth are doing quite well, all things considered.
Mango@lemmy.world 2 years ago
The breathing and eating tubes gotta cross so you can blow with your mouth and choke on cock. Non-negotiable.
daltotron@lemmy.ml 2 years ago
You could still probably blow with your mouth if you didn’t have your lungs connected, I imagine it would involve a kind of burping type of action. I think the bigger problem would be that if your nostrils closed up, you wouldn’t be able to breathe, and probably also talking would be a lot harder if your vocal chords and mouth were separate from your main air sacs.
I think the solution is probably just an easily opened and closed internal valve that separates the stomach and the lungs, rather than this bullshit we currently have with two separate valves that lead into both and open for one and then close for the other whenever it’s required. It’s still good to be able to close both when you want to, but you can already close your mouth on command, and another valve with the nose is a notable upgrade in that it keeps everyone from smelling bad smells they don’t wanna smell, and it also doesn’t take any more valves than we already have.
There’s probably some way you could fix this all with enough surgical intervention, I bet…
over_clox@lemmy.world 2 years ago
Its only a valve. Topologically speaking, the passage from the mouth to the anus only constitutes one hole.
The passage of air into the lungs is not a hole however, that is a cavity. Same difference with the vagina, that’s not a hole, that’s a cavity.
GBU_28@lemm.ee 2 years ago
People are donuts!
accideath@lemmy.world 2 years ago
No, since you have a nose. Topologically, people have 3 holes.
fossilesque@mander.xyz 2 years ago
Mmm
merc@sh.itjust.works 2 years ago
Depends on the state of your esophagus, doesn’t it? If it’s closed (which it mostly is) then your mouth and nose holes go to your lung cavity. Your anus is also part of a cavity that goes through your intestines all the way up your throat and stops at your esophagus.

The teeth thing is just because of our high sugar, high grain diet
The first* people with bad dental health were Egyptians as they lived on bread (which packs your teeth and feeds the bacteria that ferment it and make acid) before that, and until the invention spread, people died of old age with all their teeth intact
I eat very low carb - almost entirely meat due to allergies, and haven’t had a cavity since I started doing that, despite me nearly never brushing or flossing my teeth
*There were also people who lived in the tropics and ate a lot of fruit, and those with sugar cane.
Lux18@lemmy.world 2 years ago
You never brush your teeth? It’s not only good for health dude
SaharaMaleikuhm@feddit.org 2 years ago
Brush your teeth bud. People can probably smell your breath from a mile away.
KillingTimeItself@lemmy.dbzer0.com 2 years ago
brushing your teeth doesnt do much for bad breath. You want to clean the rest of your mouth to get rid of that, which is probably what they do.
psud@aussie.zone 2 years ago
You’d think. But where does the bad smell come from?
My understanding is it’s from overactive bacteria; I don’t feed my mouth bacteria with food that makes them smell
At least my partner still kisses me
Tlaloc_Temporal@lemmy.ca 2 years ago
I thought Egyptians had bad teeth because their flour was ground with sandstone, leaving sand in their bread. They ground their teeth into nothing by eating sand.
psud@aussie.zone 2 years ago
I feel like the sand thing was a guess by people who couldn’t pick why ancient Egyptians had worse teeth than everyone else in the ancient world
If there’s sand in your food you notice and it feels bad. It’s not something that makes you go “oh well I’ll just keep chomping” and that would wear teeth down, not give them abscesses
KillingTimeItself@lemmy.dbzer0.com 2 years ago
this is also common with older bread. Another reason why it’s bad, it’s probably both though.
HereIAm@lemmy.world 2 years ago
Yeeeah but they also only lived to like 30.
watersnipje@lemmy.blahaj.zone 2 years ago
Those low life expectancies are typically due to high infant deaths. Once you are like 10 or so, the life expectancy is much higher, and more informative. The life expectancy at birth is in many cases a bit misleading.
db0@lemmy.dbzer0.com 2 years ago
Similar. I don’t eat low carbs, just almost no bread, and my teeth never get cavities
mugthol@lemmy.blahaj.zone 2 years ago
Yeah but that can also be because of genetics. I eat bread everyday and still never had a cavity
psud@aussie.zone 2 years ago
I note that birds, which evolved eating grains, don’t have teeth
booly@sh.itjust.works 2 years ago
Teeth can need work from physical trauma, too. Getting hit in the head while hunting or fighting or just hiking might cause a cracked tooth, which can be deadly in the absence of dental care. Or just while eating, sometimes a stray rock or bone fragment or shell might cause an issue.
Lots of other species can regrow teeth in adulthood, even a handful of other mammals. All sorts of animals can have tooth problems in the wild, so I wouldn’t assume that prehistoric humans were exempt from that general danger.
psud@aussie.zone 2 years ago
Sure. All sorts of things would kill you, and a dental injury would be a crap way to die. The ancient stuff is from preserved hunter gatherer skeletons.
We, fortunately, have excellent dental care available so people hardly ever die of a broken tooth

Dolphins probably lament not being able to make milk come out of their buddy’s nose by making them laugh while drinking.

A horse is just an intense desire to die on four legs.
finitebanjo@lemmy.world 2 years ago
THE APENDIX HAS ENTERRED THE CHAT.
Being able to make our own Vitamin C aside, the fact that a vestigial organ can randomly decide to fucking kill you is asinine from a design perspective. Its the equivalent to building a pool in the sims and removing the ladder for the first person who wanders inside.
Liz@midwest.social 2 years ago
It’s not totally vestigial, it helps regulate colon bacteria. People without their appendix take longer to recover from diarrhea, which is important when bad water and spoiled food are a more regular part of your life.

Tails aren’t particularly common on great apes
DragonTypeWyvern@midwest.social 2 years ago
Guess it doesn’t make sense to call them great, then.
Large apes maybe.
HawlSera@lemm.ee 2 years ago
That’s cap as hell considering a saiyan without a tail can’t become a Great Ape or even an SSJ4.

Look up the recurrent laryngeal nerve.
MalReynolds@slrpnk.net 2 years ago
Shortstack@reddthat.com 2 years ago
“Evidence of evolution
The extreme detour of the recurrent laryngeal nerves, about 4.6 metres (15 ft) in the case of giraffes,[32]: 74–75 is cited as evidence of evolution, as opposed to intelligent design. The nerve’s route would have been direct in the fish-like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish). Over the course of evolution, as the neck extended and the heart became lower in the body, the laryngeal nerve remained in its original course.”
I think this is what he was getting at
watersnipje@lemmy.blahaj.zone 2 years ago
So it loops around the aorta. That’s weird, but is it a problem?
foggianism@lemmy.world 2 years ago
It’s a perfect example of non-intelligent design and evidence of evolution.

NoSpiritAnimal@lemmy.world 2 years ago
They don’t aspirate when they run, their organs slosh around and just sort of push their lungs enough to keep them alive.

I always thought the fact that turning our heads too fast can give us strokes was rather inconvenient.

Yikes. That’s why I get a little worried about the high velocity neck stuff that some chiropractors do.

Or that sneesing / trying to hold back a sneeze can give you an aneurism. But I guess although it’s rare in animals it’s not exclusive to humans.

Waiting both sneezing or trying to hold back is dangerous? What are we supposed to do half-ass it?

YourNetworkIsHaunted@awful.systems 2 years ago
Horses were at least marginally less ridiculous before people got involved. Not quite to the same extent as dogs, but compare a steppe horse with a thoroughbred and you’ll see that they’re smaller and hardier. Much better equipped to live, slightly less able to carry fully armored people on their back.

Wait what’s the deal with the horses? I want to feel good about myself today.
Septimaeus@infosec.pub 2 years ago
Their genetics have sacrificed nearly every aspect of basic resiliency for maximum speed on the plains. Most of the work caring for horses is keeping them from accidentally killing themselves. Full disclosure: I worked as a stable hand as a child in exchange for riding lessons. Will never ever own a horse.
gibmiser@lemmy.world 2 years ago
What preditor was so fast horses had to evolve to that extent??
Bytemeister@lemmy.world 2 years ago
Same for rabbits. The are basically as much lean muscle that can fit on the lighest possible skeleton.
If you pick up a rabbit wrong, they can snap their own back with the momentum from kicking their back legs.
fossilesque@mander.xyz 2 years ago
I did this too and will also never own a horse lmao. This is why horse people are weird.

Basically a 900LB Cocker Spaniel that’s afraid of it’s own farts and will eventually kill every single tree within reach. I also will never own horses.
Catoblepas@lemmy.blahaj.zone 2 years ago
Sometimes they will die because they can’t puke. Also broken legs are usually fatal even with vet care.

RizzRustbolt@lemmy.world 2 years ago
And they run around at 60mph on the tips of their toenails.
merc@sh.itjust.works 2 years ago
Humans have multiple toes because our ape ancestors used their toes like fingers. Having multiple, separate toes is probably bad for survival unless you’re using toes to manipulate tools.
Animals that have distinct toes include apes, geckos, mice, raccoons and similar animals which need them to grip onto surfaces or to manipulate things. There are predators which have separate toes because they’re a place to mount claws: eagles, cats, etc. There are animals that have separate toes with webbing between for swimming. But, for a lot of animals, separate toes aren’t really useful, so they’ve evolved away: elephants, rhinos, giraffes, horses, cows, etc.
