I should also add that common descent is not argument against occasional special creation.
For example, it has been suggested that the whale of Jonah was a unique specially created beast for an otherwise impossible task of swallowing and sustaining him for 3 days. I’m not sure this is required by Scripture, but I am sure there is no scientific evidence against this.
So science cannot definitively reject special creation, but theology cannot make the case anywhere except perhaps with Adam.
