Archaen soup?

Where would one look for extremophiles?  In our search to find evidence of adaptability thus suggesting universality or at least the triumph of our common goal, to colonize space, we look at: caves, ocean bottoms, frozen arctic cores, etc.  Why not the heart of a volcano in Africa, or the Dead Sea?

Yes the Dead Sea no one has done this yet, thoroughly have they?  If one finds even in this high salt environment microbes living and reproducing adapted to halogen systems or evidencing early divergence with genetic repositories for future endeavours ie clouds of Venus, seeding.

Wunderbar, das is gud!
