David’s comment: Note the molecule has potent antifreeze properties. Frozen bacteria can't stay alive. Then think about the anchor hook. it had to be designed before the bacteria went to the Arctic with its dual properties. Not by chance mutations. That had to travel there after appropriate preparation. Could single celled animals foresee what kind of climate they were getting into? No way.

I may have missed something here, but please tell me how you know the original bacteria travelled to the frozen Arctic. How do you know that these particular bacteria are not the descendants of those who lived there before the Arctic froze? And that when it did, the bacteria at the time did what bacteria have always done since the beginning of life: they adapted to the new conditions? No “went to”, no “chance mutations”, no “travel there”, no “foresee”. Just intelligent organisms that work out their own ways of survival when conditions change.
