ID has no position on common descent.
ID is the theory that certain patterns in nature can be best explained by intelligent agency.
There are details about what particular patterns might quality and why they are best attributed to intelligent agency but the gist of it is in the one line above. We might actually be able to publish this stuff in the normal channels if our worthy opponents didn’t Sternberg any editor that dares. But that’s a different rant.
It seems like everyone; Discovery Institute, Dembski, Behe, Berlinski, you name them and they’ve said it; ID takes no position on common descent. Any position on common descent that ID proponents may hold are not positions that ID theory requires. Personally I’m flabbergasted that in this day & age anyone could seriously question common descent. But that’s not an opinion driven by Intelligent Design theory. That’s an opinion driven by reproductive continuity, an almost universal genetic code, and mountains of secondary bits of evidence from the fossil record, molecular and anatomical homology, and etcetera. Not to get off on a rant about common descent again… 🙂
Asking what ID’s position is on common descent (it almost seems like our opponents are demanding we take a position on common descent) is like asking what neoDarwinian theory’s position is on how the universe was created. It’s simply a question that the theory does not address. People who support NeoDarwinian theory have all kinds of opinions on how the universe started. Some of them [gasp] even think GOD DID IT! Do we try to brand NeoDarwinism a religion because some of its proponents believe that God chose random mutation plus natural selection as the means to accomplish His ends? No way. We brand it a religion because some of them treat the theory as dogma instead of tentative science 😉 but I digress again.
Notice: Stay on topic. This thread isn’t about whether or not common descent is true but whether or not Intelligent Design Theory takes a position on common descent and about how the association fallacy is being used to conflate IDT with denial of common descent.
