Are there problems with the evolutionary scenario?

Size and weight, yes. But beyond that? Is a chihuahua just a sack of potatoes of a certain length?

My thoughts exactly.
Question is, do you have something to add, or just argue for the sake of arguing?
“Because I know” and “what are your qualifications?” just don’t cut it.

One or two allele, yes but “an entire genome”? Elaborate.

You just did define it as any allele change including those associated with every new birth. I am fine with that, but this definition makes Evolution totally unremarkable and gets you nowhere near “Common Descent”.
