Non-Negotiables of Darwinism

For the sake of completeness, I thought I'd include the basic tenets of Darwinism as outlined by Bill Dembski in his BioLogos essay: Southern Baptist Voices: Is Darwinism Theologically Neutral?.

Non-Negotiables of Darwinism:

• (D1) Common Descent: All organisms are related by descent with modification from a common ancestor.
• (D2) Natural Selection: Natural selection operating on random variations is the principal mechanism responsible for biological adaptations.
• (D3) Human Continuity: Humans are continuous with other animals, exhibiting no fundamental difference in kind but only differences in degree.
• (D4) Methodological Naturalism: The physical world, for purposes of scientific inquiry, may be assumed to operate by unbroken natural law.

My question is for any scientist who defines themselves as a Darwinist. Do you agree with these non-negotiables? Are there any you would like to add or modify?
