questioning facts
I was wondering if there's a factor of inevitability involved, but apparently not. It's a matter of saying, "As far as we have observed, this is the case."
Well, its inevitable that most populations are not increasing. If they were, there's be way too many animals on the planet. It seems so obvious to me I don't know how you can't see it. The claim isn't about all populations, just most of them. We can't have most of the populations increasing.
What about this fact?
5. Fact: Some traits make an organism more likely to survive and reproduce, while others make an organism less likely to survive and reproduce.
Is this inevitable?
Yes. Again the claim is only for some, not all, of the traits.
Perhaps all mutations could be neutral?
Nope, we know of mutations that are not neutral, they cannot all be neutral.
Are mutations themselves inevitable?
Yes, because of inaccurate replication.

Re: questioning facts
It is not theoretically possible that all traits be neutral?
Why do you care if its "theoretically possible"? Traits exist that are not neutral, therefore not all traits are neutral. What are you doing? whats your point?
By "inaccurate replication," do you mean "imperfect replication"?
Sure, call it what you will.
By inaccurate replication I mean replication as a thing. It is a replication that is different that the original.
By imperfect replication I think of the process. The process isn't perfect and leads to differences.
This inevitably leads to mutation?
Yes. After replication, when there is a difference, that difference is a mutation. The replication is imperfect, it leads to inaccurate replications that have differences.

Re: questioning facts
I'm trying to figure out if this process is inevitable.
For what?
Why is it so hard for you to accept something even when everyone is telling you it?
What traits exist that are not neutral? How do we know they are not neutral?
C'mon now. Just think about it. A trait would have to not affect anything to be neutral. Aren't there traits that have effects?
