It doesn’t make sense to me. Like, do you want to spread disease? This is how you spread disease.

To add on, disease from excess fat like cardiac problems is much higher associated with belly fat not butt fat.

It’s because the cheeks smear fecal matter.

Not normally, no, that should rarely/never happen. Certainly not during the evolutionary epochs of time that made us how we are today

You need to remember that prior to the modern toilet, we used to squat to shit like most other animals.

Uh, I think you are doing it wrong.

What it also does is provide balance while standing and -- more importantly -- running. Humans are the best endurance runners in the animal kingdom and out posteriors are largely responsible for that. We could chase down prey until it got too tired to run away and then club it.
Clearly this was a bigger advantage than disadvantage. Evolution is not directed.

The ostrich would like a word.

And it can have one, once it gets really tired and we catch up to it. Course then we'll be hitting it over the head with a club and eating it.
WeddingLion t1_iubnzfr wrote
It has several already
> The world's biggest bird is also the best marathon runner on the planet. While the official world record marathon time for a human is just below 2 hours, 3 minutes, an ostrich could run a marathon in an estimated 45 minutes

Yup, they're fast and can run long distances, well, fast. Humans aren't as fast but can run for longer. This is the point; we're not the fastest species, but we can run for longer than any other. An ostrich will get tired before a human.
Now we're not talking about a you-an-me human. We're talking hunter-gatherer humans.
WeddingLion t1_iuf1lhe wrote
Not many humans run longer than a marathon. That's kind of our baseline long distance.
sterlingphoenix t1_iuf5zr5 wrote
That's our modern, civilised human baseline, maybe. Our ancestors, who did chase animals to exhaustion, would laugh at our mere marathon.
WeddingLion t1_iuf7jo5 wrote
Doubtful. Our ancestors chased food for survival. Racing an animal for that far isn't very efficient. The first recorded guy to run a marathon (to Marathon) died of exhaustion. We have so many resources that people do it for leisure.
The fact that marathon running is an Olympic event that people train for their entire lives directly disputes your comment. Not to mention the fact that ultra marathons also exist.
Our ancestors would be like "but why?"

Again, you're talking about modern humans.
You can read about this hypothesis here. There are critiques of it, but those are of the evolutionary path, not the fact that humans are amazing endurance runners.
_BigDaddyNate_ t1_iudj8au wrote
He said endurance, not sprinting and the such. Endurance is how long you last regardless of speed. And ostrich is fast but couldn't last.
WeddingLion t1_iuf1te8 wrote
I mean. If you think you can out endurance an ostrich, go ahead.

Are you talking about the glutes? Because we use those to walk. Walking is more important than disease.
And I'm not getting where the "that spreads disease" part comes in. Most disease comes from the presence of the anus, and the contents from it. And those things are also necessary, so we can't just get rid of it.
