    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.

      I would say it’s even smaller in number. Because some combinations would not work and might kill you.

      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.

    If different people with similar visual characteristics have similar behavioral characteristics, doesn’t that imply that perhaps we can judge a book by its cover?

    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.
