> The many valid sequences are relatively nothing compared to the infinitely many invalid ones, right? I dont know about the relative numbers but I don't think you do either? Are you begging the question or can you quantify? > You think that's "quick" for dna which is made up of billions of 6-base-sequences and for a species that can only reproduce sexually once every decade or so at best? We didn't start from scratch, we are very very late in the game, and the groundwork for us was laid by millions of other species that can replicate quickly, often very quickly. Unless you believe the Earth is only six thousand years or so old, in which case we might as well leave the discussion where it is.
