New Extremophiles: Arctic snails! (Introduction)

David’s comments:
I assume the life found got there when the Antarctica was warm, and adapted as the climate changed. All living material is made to be tough. And to survive makes no mistakes as seen in complex multicellular forms.

It seems as if extremeophiles can be larger than microscopic. Again we see life thriving everywhere on Earth.

dhw: Yes indeed, and it is the astonishing variety and adaptability of these organisms that makes me all the more inclined to accept the theory that they are possessed of an autonomous mechanism which enables them to thrive in all conditions. This is not an attack on the concept of a Creator God – on the contrary, in my view such a mechanism provides the most convincing evidence of a designer. But the greater the variety (both within species and in speciation itself), the less likely I find it that every one was preprogrammed 3.8 billion years ago, or that a designer kept stepping in to make all the necessary adjustments to enable each organism to survive each change in its living conditions.

I can't disagree that a powerful epigenetic mechanism following some instructive guidelines may exist, but is yet to be found. Like yesterdays double DNA discovery.
