It is, after all, a smallish planet. Bound to be some duplication.
I always wondered about this in terms of I have known some types of folks that look similar and actually often have similar social traits and this includes me to.
So should you avoid having kids with someone you look similar too then? Like is it that the virtual twins have genetic similarities akin to 3rd cousins or siblings…
Thats plain rediculous. How can I possibly find someone good enough looking then?
Why didn’t they give FB-007 shirts?
Any qualified 007 could report to Q for cutting edge clothing and gear?
Strange, almost like phenotype is dependent on genotype?
It seems this includes genes that don’t play a direct role in the formation of facial features.
Yes, but it’s not necessarily the only way that would work. So this is very neat!
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 ;)
You think this sounds angry???
Can you stop yelling?
Does that mean you could guess a person’s personality from just their look?
Well not their face, but definitely the shape of their skulls!
Of course you’d say that. You have the brainpan of a stagecoach tilter!
Big, if true
Colossal, if legitimate
Gargantuan, if verifiable
Humongous, if credible
It is still interesting. I wonder if epigenetics plays a larger role, or if face look is tied to other random traits.
The article says epigenetics don’t play much of a role in it, it’s all genetics.
Or maybe we’re living in a simulation and whatever is generating it only has a finite number of characters. 😲
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.
Yes, but the article says that certain combinations occur more often that if it was random. People with similar faces tend to have similar genes that are nor related to facial features.
I would say it’s even smaller in number. Because some combinations would not work and might kill you.
That’s not exactly true. A lot of DNA is redundant, and a lot of DNA is dead code that doesn’t do anything.
Since you’ve only been told that you’re wrong, and I was also under the impression that there was a lot of junk DNA in our genome, I did a little digging and found this article that explains the progression of our understanding pretty well: https://www.sciencenewstoday.org/human-dna-98-of-your-genetic-code-is-junk-or-is-it
The TLDR is that the original junk DNA hypothesis is based on the fact that only ~2% of DNA is actually used in mapping out protein-construction. That was generally supported by the science from the 70’s to the early 2000’s. What scientists have found in the decades since then is that a lot of what DNA does involves regulating activity in the cell and responding to changing circumstances.
Is it really dead code, or we haven’t found out what it does?
That’s a very outdated idea.
…We all look like 98% similar.
they all look the same…
thinks some alien, prolly
I love this short story!
@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 have a great answer other than of the 32 studied, these were their stratification:
Related to population stratification, among the 16 look-alike pairs, 13 were of European ancestry, 1 Hispanic, 1 East Asian, and 1 Central-South Asian.

But whether people who look close enough to perform as another, such as the “Chinese Obama” (Xiao Jiguo) I can’t say.
Then there’s Indonesia’s former president, Joko Widodo:

It would be interesting to get the researchers to analyze their DNA.
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.
Oh good, phrenology is back.
Pictured “doppelgängers” have very little common outside pose and hair/beard styles.
