Evolution News & Views recently broke this fascinating story:
Bacteria, yeast and humans have very similar proteins that form slipknots. As Ann Gauger has already noted here, this would seem to pose a knotty problem for evolution. Evolutionary theory, however, is like The Blob. It sweeps up every obstacle in its path and moves on, growing bigger, fatter and uglier all the time.
Evolution's immunity from falsification is evident in a Science Daily article, "Untangling Knots, Slipknots in Species Separated by a Billion Years of Evolution." So you think a string of amino acids that can automatically fold itself into a slipknot gives some pretty good evidence of intelligent design? The suspicion might seem more like a sound inference when you realize that this slipknot performs a vital function: slipknot proteins, that "might look like shoelaces for cells," actually "stick through the cell membrane like pins in a pin cushion and help the cell sense and respond to its environment." That inference might be considered confirmed by the knowledge that evolutionists admit the basic design of slipknot proteins has not changed for a billion years, and is basically the same in bacteria and humans.
But then ENV explains how Darwinists spin this into a story that makes evolution look good (unless you look at the knotty details).
Ah, but evolutionists are clever. Since all they have to do is assume their belief to be true and then go on from there, the rest is easy: make up a story to fit the observation into the grand evolutionary tale. A good short story, however, requires a source of conflict. Joanna Sulkowska, from UC San Diego, shows how this is done for "strongly conserved" proteins:
"The slipknot is surprisingly conserved across many different families, from different species: bacteria, yeast and even human," Sulkowska said. "They have really different evolutionary pathways, yet they conserve the same kind of motif. We think the slipknot stabilizes the location of the protein inside the membrane."
Lest the National Center for Science Education fire up the red alarms over a potential ID flare-up, Sulkowska's story quickly calls on Evolution to douse the flames with Darwin magic water (read more).
