Bits and pieces

Maybe life in Earth started between thin sheets of mica ('glimmer' in Swedish).  I remember pulling thin sheets of muscovite (muskovit) mica apart at some of the old mines we visited when we were kids, thinking they were like layered bendable glass. I was told that in previous times people had used mica as 'windows' on their woodstoves for that reason, but I am not sure if it is true.  Scientists don't know if the mica theory is true either, but it is certainly a fascinating hypothesis that the first cells developed between thin mica layers.
