Tbf, our teeth aren't bad. They just didn't evolve to consume so much sugar.
-
From an evolutionary standpoint we just have to survive long enough to reproduce, if we can't eat past age of reproduction there's no evolutionary pressure to change that.
Thank goodness for modern dentistry.
-
That’s completely untrue.
Evolution applies to the entire lifespan — if we could “reproduce” but died in childbirth every time, our species would have gone extinct long ago.
Parents and grandparents also contribute greatly to the success of a child long long after they’re born, helping to ensure it also survives to reproductive age.

Bro, eating oranges puts our tooth enamel in a weakened state. If we were designed, it was by an idiot.
-
Oranges do not naturally have that much sugar.

Half our expected lifetime was our expected lifetime back when they evolved. Teeth are doing quite well, all things considered.

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.

You never brush your teeth? It's not only good for health dude
-
Brush your teeth bud. People can probably smell your breath from a mile away.
-
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.
-
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

-
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.
-
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
-
this is also common with older bread. Another reason why it's bad, it's probably both though.
-

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.
-
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, I know about my lack of cavities from a pair of several x-rays and a check up while replacing a filling from when I ate the common diet

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

THE APPENDIX HAS ENTERED 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.

I am 99% sure humans are supposed to have tails
-
I sure as hell am supposed to. A big, floofy one.

Ah yes, you are indeed one of my kind.

Look up the recurrent laryngeal nerve.
-
I did, for the lazy
Your point ? I didn't go deep, but nothing jumps out at me.

"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
-
-
So it loops around the aorta. That’s weird, but is it a problem?
-
It's a perfect example of non-intelligent design and evidence of evolution.
-
high ping to your larynx, basically

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?
-
Rupture an existing one, right?
-
-
-
imagine having a stuffy nose and you can't breathe with your mouth.
-
the lack of a highly clickable abstract and title that ignores the last names of many of the people involved leads me to believe this is a satire
-
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.
-
We're God's creation but God is a lazy kid that rushed the science project for the whole semester in six days and barely half assed it hoping no one digs too deep into it
-
as long as you ditch the whole "omniscient and omnipotent" part, god is pretty relatable.
i'd like to see you do better when you're literally creating the fucking universe on your own.

What use is grief to a horse?

Wait what's the deal with the horses? I want to feel good about myself today.
Edit: Wow, those bastards have it rough.
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.
What preditor was so fast horses had to evolve to that extent??
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.
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.
Sometimes they will die because they can’t puke. Also broken legs are usually fatal even with vet care.
To add on why broken legs are fatal: its because horses are so big, that even with a sling, they cannot support themselves well on 3 legs. And lying down is also not an option as their own weight will crush their internal organs if they stay down for too long.
The term healthy as a horse is mostly survivorship bias
From what i read here there's no unhealthy horse, it's either healthy or dead.
They only have 4 toes total.
And they run around at 60mph on the tips of their toenails.
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.
