Thank you for your reply and the link - but again I must aver that there is nothing in the [microbiologists'] laboratory experiments to falsify any other explanation for what the paleontologist observes in his digs.

The bottom line is that nothing discovered in the laboratory can falsify either special creation or panspermia.

While it is trivially true that intelligent design cannot be falsified, I fail to see what that has to do with the question of what mechanism intervenes to prevent microevolution from becoming macroevolution.
