I have posted the reasons did you read them ?
Look back they went into detail by the amount of mutations that happen naturally not induced. And by the results we see that comes from mutations. Even scientist on your side know these arguments are a problem for the theory.
Look back through the thread they go into detail.
When we induced mutations in the drosophila most were harmful and all flies became weaker and died off prematurely. We also have observed many mutations that happened naturally. There was not much difference from the mutations that were induced and the ones that happened naturally.
By there being many more harmful and neutral mutations it is overwhelming in number compared to beneficial mutations. But even the beneficial mutations come at a price. How is a mutation a benefit to me if i have to have a blood disorder to fight off a disease ?
Yes, most mutations are harmful in those experiments. Yet similar experiments with yeast show a 7% rate of harmful mutations. You're are correct with the statement of neutral (that is, mutations that have little-to-no effect on an organism) and harmful mutations happening more often than beneficial ones. An important question to ask though, is what simply is the rate of these mutations happening at? I can guarantee you these mutations don't happen nearly as often as you suggest by the fruit fly experiment, especially in other organisms. This is considering that these mutations are induced artificially via radiation which bumps up the mutation rate, and mutations don't actually happen like that in nature.
Another point is that organisms do in fact have DNA repair, repairing the majority of these mutations before they can actually have an effect. So every single mutation isn't simply allowed to occur.
I don't get your last question. Is the blood disorder caused by the beneficial mutation? Because your question sounds like it's pre-existing and unrelated.
No, those numbers were from natural occurring mutations.
That's fascinating, actually. But that still doesn't answer how often mutations happen.
