Rarely is human genetics this simple. For ages geneticists thought large swaths of the human genome were "junk" and over time more and more of it has been proven to have a purpose or function, it just wasn't readily apparent for various reasons. Think of the human genome as sort of the ultimate dependency hell...

Nature does not refactor. There's the laryngeal nerve somewhere in the neck of mammals that has to go around a blood vessel. On Giraffes, this runs all the way down the neck, around said blood vessel, than back up, all that just to connect two places in the upper neck that are inches apart. Evolution writes the ultimate spaghetti code. More info: https://berto-meister.blogspot.com/2011/08/unintelligent-des...

Nature rarely* refactors. Sometimes random mutations refactors, which leads to efficiencies which leads to evolutionary advantages.

If nature doesn't refactor, then why are there so many crabs?

Probably good that we lost them. Judging by photos [1] of some of the rare cases of humans who were born with tails human tails wouldn't be aesthetically pleasing. Although perhaps human tails that are the result of something going awry might not be a good indicator of what human tails would be like if we had kept them.

If we kept tails both the tails and our sense of what is attractive would be under evolutionary pressures so they probably would be normal to us!

Exactly. I still find noses and ears to be such noticeable protrusions once I let go of my knowledge of human faces.

I suspect our tailed ancestors slept, locomoted, and defecated.

I think we'd definitely have to rethink our toilets, though. Don't want your tail hanging in there while you're doing your business.

In much of the world (weighted by humans) people use squat toilets. So, problem is solvable by installing one after your CRISPR tail procedure.

Imagine if it was covered in pubes. That would definitely be worse.

I'm not sure that would be as much of a problem as one might think, considering that many if not a majority of males today do just fine with their faces covered in pubes.

And also the people with a head-full of "pubes". People and cultures adapt.

Clearly refactored for memory safety.

"Octopus throat runs through brain" and the "blood supply in FRONT of the retina cones n rods" were the other 2 that are often mentioned.
