I will admit that I didn't read the entire article but this seems to be covering an argument among scientists about the mechanisms that cause new traits to occur in organisms. What specifically does this article say that evolutionists are retreating from?

There seems to be no indication among the scientists that evolution may not have occurred.
There seems to be no indication that natural selection was going to be put aside as one of the mechanisms of evolution.
There appears to be no redefinition of evolution or the basic premises of evolution.

Why should a shortfall in knowledge about the internal workings of evolution prevent us from teaching what we do know? See my examples of your "X" statement.

"We insist on indoctrinating you and your children with the idea that the force of gravity exists between 2 masses. We haven't worked out what the mechanism of gravity is, but that's none of your concern."

"We insist on indoctrinating you and your children with the knowledge that Jesus is the sacrifice for the forgiveness of your sins. We haven't worked out Why God required Jesus to be sacrificed in order for God to forgive us, but that's none of your concern."

If you wish to discuss specific portions of the article, then I will read the article and respond.
