Actually, I think that you just lost it completely.
"But note what your quote and you are suggesting, that the virus is fine-tuning and improving itself to better attack its host. Remember one of the stipulations of evolutionary theory, that any changes in an organism cannot be for a purpose. It all has to be based on chance mutations. I agree with your writer, I think it is obvious that even single-celled organisms have a type of intelligence that enables them to adapt, but this is the kind of artificial thought straight-jacket that evolutionist force on others."
It is not intelligence that allowed this virus to more effectively attack its host. It is natural selection acting upon the variation that is there.
