Well you did leave out what percentage of mutations are beneficial. Maybe truth challenged suits you better. Or you just don’t like to state your assumptions upfront.
BM: please read a little bit about natural selection.
If a mutation is not beneficial, it does not carry on to subsequent generations (I am oversimplifying a little). This involves a similar explanation to why proteins fold, although they should not, according to "your" math. A protein is a huge molecule, with many chemical bonds. These bonds can rotate, and this creates an enormous, astronomical combinatorial space of particular angles. So how come, a Creationist would ask, that an enzyme can fold into an organized structure? Yet we know that they fold, and the concept of cumulative selection (accepting PARTIALLY correct organization and thus pruning the tree of possibilities) provides the answer as to why.
Maybe you simply have no freakin’ clue what you’re talking about but need to claim other people to be challenged, even when they show you’re full of shi’ite.
Question my scientific credentials again.
Question my math skills again.
Next step is to call me a liberal.
