> What if the cells of the brain have their own genome because each one of the billions of cells has a near specific specialized function. That's the opposite of my interpretation -- it goes to show that even in the face of inevitable statistical noise, biological systems are incredibly fault-tolerant and durable. And furthermore, a neuron is just a neuron. It's unlikely that the genomic differences in a genius's neurons are significant compared to the overall genetic average which gave rise to a certain structure, certain proteins being more common, etc.
