Wait what's the deal with the horses? I want to feel good about myself today.

Edit: Wow, those bastards have it rough.

[–] [email protected] 191 points 2 months ago (4 children)

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??

[–] [email protected] 77 points 2 months ago (1 children)

Big cat. You're aware of the cheetah? Just picture that but not in Africa

You know what really caught me up: where are horses native to?

[–] [email protected] 64 points 2 months ago (1 children)

There are wild horses on the Mongolian steppes.

All other horses are domesticated. Even the free horses in USA and Australia are descendants of domesticated horses.

[–] [email protected] 53 points 2 months ago* (last edited 2 months ago) (1 children)

You're right! But also, horses were native to North America but they went extinct 10,000 years ago and weren't introduced until much more recently.

PBS Eons has a couple good videos on both horse evolution and domestication.

Us. They basically tried to beat pursuit predation by outrunning the distance humans will be willing to track over.

It did not work, they went extinct in North America because of how much it did not work.

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.

[–] [email protected] 48 points 2 months ago (3 children)

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.

[–] [email protected] 112 points 2 months ago (7 children)

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.

[–] TheDoozer 60 points 2 months ago (1 children)

Oh, wow, I had always thought that shooting a horse with a broken leg was an act of brutal expedience, not mercy.

Also, don't they need to run to move food through their digestive tract? Or to force themselves to cough if they have something stuck in their lungs? I think there is some sort of dependency of basic functions that relies on the movement of their lungs/stomach going back and forth while running that they can't easily do if they just stand in one place all day

The term healthy as a horse is mostly survivorship bias

[–] [email protected] 39 points 2 months ago (1 children)

From what i read here there's no unhealthy horse, it's either healthy or dead.

They only have 4 toes total.

[–] RizzRustbolt 41 points 2 months ago (1 children)

And they run around at 60mph on the tips of their toenails.

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

[–] [email protected] 74 points 2 months ago (3 children)

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.

[–] Hawke 55 points 2 months ago* (last edited 2 months ago) (12 children)

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.

The breathing and eating tubes gotta cross so you can blow with your mouth and choke on cock. Non-negotiable.

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.

[–] accideath 24 points 2 months ago (18 children)

No, since you have a nose. Topologically, people have 3 holes.

[–] chuckleslord 18 points 2 months ago (3 children)

7, if the cut-off is 60 microns (tear ducts). Smaller than that, we're essentially Swiss cheese.

tbf horses have big dicks, it could have been worse for them

[–] [email protected] 50 points 2 months ago (2 children)

You stand on your toenails

[–] [email protected] 29 points 2 months ago (1 children)

Both valid points. I will still need some time to take this all into consideration.

[–] [email protected] 25 points 2 months ago (1 children)

Consider this: horses can't puke and just die if they eat something bad

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

[–] Anticorp 33 points 2 months ago

A horse is just an intense desire to die on four legs.

[–] finitebanjo 30 points 2 months ago* (last edited 2 months ago) (1 children)

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.

[–] [email protected] 42 points 2 months ago (3 children)

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.

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 31 points 2 months ago

You never brush your teeth? It's not only good for health dude
