Did you go to the link I showed Red?
As someone already noted, the fact that mutations are rarely beneficial is pretty obvious - those which aren't become extinct and those which are survive.
Given that you're a creationist, how do you explain all of the extinct species?
Edit - as to names of people to read to refute the wildly incorrect odds quoted, I suggest starting with Francis Crick himself and read as much of his work as you can
