My position is very clear and consistent: all mutation, no matter how small, how big, occur randomly. There is no causal relationship between them. NS has nothing to do with occurance, it only works after they occur.
But you said:
It is you, Darwinist who claims mutation occur by natural selection
The first statement you made above is correct and no biolgists makes the claim that you say they do in the second quote.
I asked you where you got the idea that anyone did make such a statement. Can you explain that?
