Only there's one catch: >you don't get to move to the left. *How* do the beneficial mutations get amplified by Natural Selection? How does that "catch" in Paul's experiment relate to N.S.? Why don't some trials cause us to move to the left, or even cause us to start again from the beginning? Why must natural selection work the way Paul says it does? >You can go pretty far, with enough trials. Have there been enough yet? Why, of course, we've gotten pretty far haven't we? :-) -- Paul Dubuc cbscc!pmd
