Thanks for posting this, Randy. It occurred to me that (obviously!)
there is no dialog between creationists and those of us who accept
evolution. It would be interesting to see what might happen if stories
like this were sent to ICR and other creationist organizations. Then
we could maintain a database of stories sent and creationist response.
I suspect we won't get much of a response. But the value of
maintaining the database is that it could be presented to creationists
to establish that we, at least, had tried to establish dialog.
