Peter Borger's argument is this:
1. It appears that mutations are not completely random in the genome.
2. Evolution posits a "uniform" randomness.
3. Therefore these areas of non-random mutation must be from a process other than evolution.
4. Therefore this process is "directed" mutation.
5. This means that the coding of these genes was caused by intelligence and not a random process.
6. The only intelligence that could produce such genes is the Christian God.
I think that about sums it up. All dillydallying aside.. it's a pretty weak argument. It goes down in flames on #2. Evolution does not require mutations to be entirely random. It works well with not completely random mutations, and it also works with psuedo-random change, or any sort of stochastic process, where variation is generated in the genome that can be culled by selection.
In any case, you can't jump to #3, or to #4 without assuming facts not in evidence.
