God can inject mutations into common descent whenever he likes to produce what ever forms he wants.
God alternatively could have made everything without a strong signature for a tree.
Of God can de move create life, he can certainly do both these things. #1 deomonstrates why ID arguments are not arguments against common descent. #2 demonstrates that God could have made life in a way that did not look like common descent, but he did.
That is why the tree structure is de facto evidence of common descent, even when taking theology into account.
The evidence for common descent of man is much stronger and clearer than UCD, which is why I focus there. If this is true, then there is no reason to theologically object to UCD. Nor is it clear why it matters theologically or scientifically.
You have been consistent here and we have common ground that common descent of man is more likely then UCD. All that being said I think it is an untested hypothesis as we cannot connect the genetic changes with the morphological changes yet.
I think everyone believes in some common descent so the claim is trivial in itself.
I agree with you that the argument should be on more specific claims like human evolution. I think we are in the first inning of understanding if this is true or not.
I do believe that the hierarchal structure that we see is the result of design and not ancestry alone.
Peaceful Science is one of the few places that gets that common descent and design perspectives are NOT mutually excluding, or even necessarily opposing ideas. One is cogent in explaining patterns we see in physical lineage, the other tries to account for the “something extra” of things like human speech, consciousness, abstract reasoning, etc., which have yet to be shown to be incremental improvements in nature. Even if they are, it’s not “God of the gaps,” but God’s handiwork, first and last. Nature in this statistically unlikely Anthropic universe did not “just so happen” to turn out to be as it is; to maintain otherwise is no less a faith position than is theism or multiversism.
