No. As a matter of fact, from sequences obtained so far, the critical difference in this body plan change is contained in only 10 amino acids. So, one piece of the puzzle has been demonstrated. Are you saying that other pieces of the puzzle could never be demonstrated similarly? Or that all the changes for each puzzle piece had to happen simultaneously?
OK, just so we are clear that this is ONE PIECE of a puzzle. A puzzle that may have many thousands of complicated pieces that may or may not have to be laid out in a certain place and order to go from shrimp to fly.

No and no. Don't see how one could get that from my post (#84 or 92?). Your #78 imlied that only 17 changes in amino acids were required to go from shrimp to fly. You now say to make this 'one piece of the puzzle' it would only take those changes. That is more like it. But we have always known that you could make a fly from shrimp DNA if you could make enough changes to that DNA. But is there a viable chain of organisms for every possible change required along the way? Not all of the changes would have to happen at once, but many would have to occur in conjunction with others for the new organism to be a viable one. Is there a possible path between the two? And even if possible, is there enough time for it to have reasonably happened by chance?
If only ten mutations were required to go from shrimp to fly, scientists would have long ago proven evolution by making new critters from old ones.
