From the Opening Post:
"Most creationist arguments can be summarised as "complexity, complexity, complexity - therefore god"
We have all heard the illustrations about the odds of (insert favourite example) evolving, being less than 10,000 monkeys typing Macbeth by pure chance.
Evolution is not like that.
The genius of Charles Darwin was in recognising the power of natural selection as an accumulator of small random changes.
Imagine our 10,000 monkeys randomly typing until one of them by pure chance comes up with "When.."
At that point all the other pages are scrapped and every monkey is given a copy of this page. We observe some more until another monkey adds "shall.." and so on through thousands of iterations. How long would it take to achieve "When shall we three meet again? In thunder, lightning, or in rain?" Completing the full play now becomes inevitable.
Evolution is a little bit like that."
Not really!
Your example gives perfect selection in one generation with no reduction in population size. In order to acheive perfect selection, you would have to have the 9,999 of the monkeys with the wrong typing be ELIMINATED without typing again. This reduces your population to only 1 typing monkey (the one that typed "When"). One monkey would be extinction. Your example killed the population.
Even if one monkey could somehow reproduce it would take many years for the population size to increase back to 10,000 again. Such a small population would be very vulnerable to extinction by chance processes.
