"Varying all the codons independently gives 3^(3*10^6) functionally equivalent (hence viable) humane genome variants. That's ~10^954242."

I don't think that anyone is arguing over the quantity of potential permutations, but rather, the quantity of viable permutations...

but rather, the quantity of viable permutations...

How is it that functionally equivalent variations of a viable genome would not be viable?
