Aren't all humans 99.9% similar already?

If 93% is enough you could just take any ape at that point.

That's DNA, not facial structure

Yes. You take something out of context to make it look stupid. A 93% DNA match is extremely stupid, just like a 93% AI facial match.

TIL that I'm a joke

No. I fully support fartographers and consider them a staple of our society.

[–] fartographer@lemmy.world 2 points 1 day ago

TIL I'm also a staple. (Oh yes, this joke has nowhere to go but down, and I'm fully buckled in)

IIRC there are an estimated roughly 1 Billion different allele combinations that deal with appearance so hypothetically you should have 6-8 doppelgängers somewhere in the world.

I definitely saw a video about this.

There’s no objective measure for quantifying similarity. We can measure relative similarity, though—but that scale will vary depending on what it’s relative to.

We could measure genetic similarity relative to a typical unrelated person, or relative to the nearest non-human animal, or relative to the most distantly-related living organism, or relative to random noise. (And you can do the same for facial similarity.)

Yeah I wonder what a 0% match looks like.

I was going to show a photo of my twin but that example works too

Humans do have really low genetic diversity compared to most other organisms. Not as bad cheetahs though!
