In the neomura theory it was very unlikely that earlier organisms, bacteria, trapped in their non-extremophile yet sturdy protein exoskeleton cell wall, would be able to loose it to develop a new extremophile one (archaebacteria) respectively develop an endoskeleton flexible cell (eukaryotes).    From Wordnik.com.  [HARPS Discovers 32 New Exoplanets | Universe Today] Reference
