One prominent scientist who opposes the three domain system is Thomas Cavalier-Smith, who proposed that the Archaea and the Eukaryotes (the Neomura) stem from Gram positive bacteria (Posibacteria), which in turn derive from gram negative bacteria (Negibacteria) based on several logical arguments, which are highly controversial and generally disregarded by the molecular biology community (c.f. reviewers' comments on, e.g. Eric Bapteste is "agnostic" regarding the conclusions) and are often not mentioned in reviews (e.g.) due to the subjective nature of the assumptions made.
