Is it possible to rationally believe YEC?

C2f is today evidence for common descent. But at some point in our ancestry the fusion did not exist. So whether or not Adam had the fusion would only indicate whether he existed prior to or after the fusion became fixed in our genome. By itself it would not indicate common ancestry. Actually, common ancestry would be determined by the genome as a whole.

Strictly speaking, C2f isn’t necessary to the type of issue I’m pressing. It’s just the particular example that came to mind. If “the genome as a whole” indicates common ancestry then I can just ask whether Adam’s “genome as a whole” would have been significantly different than that of POG. If not, then Adam’s “genome as a whole” would have indicated that he shared common ancestry with POG. In which case, there would be evidence against Adam’s de novo creation, though not necessarily evidence against Adam being de novo created with evidence against his being de novo created.

even though it would look like Adam shared common ancestry with humans “outside the Garden”, he didn’t.

Right… that’s really the only point I’ve been pressing on since I brought up the C2f issue.
