The Importance of Genetic Constraints in Writing

We tend to use nice natural strokes and quite often use alphabets. I mean, but clearly that's not a product of some writing instinct because writing's even around for a few thousand years. And it's also a fun of you have genetics, I think. We were talking about this in my department the other week: If you look at how geneticists study other parts of our genome and our body, it's very rare that you have like one gene that does one thing like that.
