An ancient monotreme with partially migrated, not-here-not-there ear bones calls the heretofore accepted evolutionary scenario in doubt. I suppose it could be used to argue for Utterly Incompetent Design (UID).

You would, since you have an agenda. Others might infer a common toolkit with common solutions.

This means that natural selection must have driven the same rearrangement in independent groups, after the monotreme split

P.S. What makes theTeinolophos specimen surprising is a large groove in its adult jawbone, which indicates that the smaller bones had not yet detached.

"Not detached" does not mean "partially migrated" in my book.
