I’m not christian and I assumed the experiment didn’t allow for evolution as it was not specified in its parameters. I assumed that the monkeys were a horrible (and very wrong) analogy for random number generators, were immortal, and had no time for making offspring as they were all trained and consumed with typewriting, or physically separated from one another.

The monkeys would produce wildly more limited results than a random number generator mind you, and they are essentially frozen in evolutionary time, so they are not going to be writing shakespear.
