Claim CF011.1:
Dawkins (1986) demonstrated a program that starts with a random string of
letters and, via random copying errors, evolves it into the phrase
"Methinks it is like a weasel" in just a few generations, demonstrating
the power of natural selection unaided by intelligence. But
intelligence is involved in predetermining the target sentence.

Response:
- Dawkins's simulation was plainly stated in his book to demonstrate
selection, not evolution. It was intended to show the difference
between cumulative selection and single-step selection. Attempts to
apply Dawkins's simulation to evolution as a whole are a misreading of
his book.
- Other evolution simulations do demonstrate all the salient features of
evolution (Lenski et al. 2003). They do include a fitness
function, but simulating fitness is part of simulating evolution.
