You are all trying to convince me that forcing a small stupid self replicator to evolve encryption is harder than the whole evolution of men?
Well, you seem to have arguments against the evolution of encryption and none against the evolution of man; so yes, this would seem to be the case.
The problem with encryption, as far as I can see, is that it has to be achieved in a single bound. Human evolution, on the contrary, can (and,
vide the fossil record, did) progress through a series of viable intermediate forms.
