Of course there are a lot of ifs. I myself said that the vast majority of mutations will disappear. Your position is that evolution is impossible. Given 6,000,000 years to evolve from the point where man and chimp diverged, you have to claim not merely that most mutations will disappear, but that virtually all mutuations will disappear.
Absolutely correct and for the reasons given in my post#563 which you did not copy:
So all that could take over a whole population is a largely beneficial mutation. Problem with that is for any new feature, for any new function, indeed for any new gene you would need a multiplicity of mutations. These are not all going to occur at once. Since neutral and slightly beneficial mutations will die off very quickly and only spread to very few individuals, this accumulation of mutations is impossible and therefore evolution is impossible.
One beneficial mutation is not impossible though highly unlikely as you yourself admit. However several beneficial mutations, all of them working towards the same goal, occurring at random is totally impossible. Just one would constitute a miracle. The millions of them that would have been necessary to account for all the diverse features of the millions of species alive right now as well as the progress from bacteria to human is utterly impossible that is why the only rational explanation is intelligent design.
