Evolution: Two Domains of Life or Three?

Abstract
That Bacteria, Archaea and Eukarya (eukaryotes) represent three separate domains of Life, no one having evolved from within any other, has been taken as fact for three decades. Recent work shows this to be untrue. Eukarya arose from well within Archaea and are specifically related to newly discovered archaeal species with eukaryote-like features.
