Rephrasing your question as per your response to John Harshman:

Does anybody in TO doubt that all genome evolution during the last four
billion years in any given ancestral lineage is explainable by
mutations and changes in allele frequencies?

Hell, for all I know, I could have been stolen from gypsies and raised
by WASPs.

We can compare your DNA to the DNA of gypsies.


If you allow under "mutations" such things as a potential meal thriving
inside a simple cell and evolving into symbiotic relationship so that
they are considered one entity, a virus embedding in a chromosome
becoming one with the cell, or gene exchange (or DNA strand exchange)
between separate cells then I have a high confidence level for
mutations and changes in allele frequencies being a plausible
explanation for ancestral lineage.

Any type of symbiotic relationship can be broken down to the
co-evolution of genomes. And in the case of endosymbiosis, one of the
genomes eventually became the genome of an organelle. And I classify
horizontal gene transfer as an event of mutation and fixation.


I am not so committed to it that I couldn't be swayed by good evidence
to the contrary.

No one should be:)


Perhaps other types of life emerged during the last 4 billion years,
such as DNA with a left-hand spiral, another right-hand spiral
Indistinguishable from ours, DNA with a different code, RNA based life,
or something else entirely. But one of those types will have an edge
over the others in competition for resources and eventually win out.
It's like the house odds in Vegas. Also, there's a comparison with
tournament competition, where all but one is eliminated.
