Can Unguided Evolution be Simulated on a Computer?

-
The question of the day seems to be how to simulate unguided evolution. The question stems from the fact that both evolutionary and genetic algorithms model guided, ie intelligently designed, evolution. They do not model natural selection and drift, ie the main mechanisms of unguided evolution. Those algorithms have a goal whereas NS does not.

So how can unguided evolution be modeled? I say it cannot be modeled due to its very nature. And that, dear readers, is the problem. Unguided evolution cannot be modeled. It cannot be tested. It does not have any entailments. And all of that is what makes it pseudo-scientific bullshit.
