Or maybe we're living in a simulation and whatever is generating it only has a finite number of characters. 😲

Strange, almost like phenotype is dependent on genotype?
You're telling me people whose genetics make them look similar have similar genetics???
Not proven until now.
These “duh” comments are always here in these situations.
We're just joking around here my friend :) of course it's important to confirm, still funny every time
I hope so, that’s good to hear. Some people seem so pissed off when making such comments about “useless” studies. 😔
People in text always sound more pissed off than they were. That mostly has to do with your expectations though ;)
Big, if true
DNA has a limited number of genes. Considering the enormous amount of functions they need to encode, the number of genes for each function becomes relatively small. 8 billion people and thousands of generations, we’re bound to have duplicates.
That's not exactly true. A lot of DNA is redundant, and a lot of DNA is dead code that doesn't do anything.
Is it really dead code, or we haven't found out what it does?
I would say it's even smaller in number. Because some combinations would not work and might kill you.
...We all look like 98% similar.
they all look the same..
thinks some alien, prolly
@RegularJoe I'm curious about how this might work across ethnicities. I can't point to a photo, but several times, I've noticed people from other continents who could easily be someone I know here, except they're African, or Asian, when the person I know is white, just for example. Under the expected differences in hair, eyes, etc, the basic facial structure is the same. A DNA match seems less likely in these cases.
I don't think it's about a DNA match. Those people you mention could share more DNA than the rest of us, which could account for their similarities, but their DNA will never "match" anyone else's.
All humans are within 23 degrees of being cousins. The thing that surprised me most is that sub Saharan Africans are the most diverse genetically speaking.
Nice to see research shared like this, thanks. I've always been fascinated by facial similarities. The other thing I often look at, especially when pronounced, is the difference in the two hemispheres of the face.
Pictured “doppelgängers” have very little common outside pose and hair/beard styles.
