I was using Pseudomonas to argue against creationist nonsense back in 2001 on talk.origins. A species of Pseudomonas bacteria had evolved the ability to synthesize nylon oligomers through a frame-shift mutation. Considering that nylon did not exist before (about) the 1940s there is no way this could be anything but "evilution".

Well, it seems that now a bacterium that eats plastic bags has also been found. Dear creationist readers, please feel free to plug your ears and close your eyes. Satan is just fabricating this nonsense to test your faith.
