WebbSome of the early phylogenetic trees of the prokaryote world were morphology-based; others were based on the then-current ideas on the presumed conditions on our planet at the time that life first developed. Around 1950 many leading microbiologists had become pessimistic with respect to the possibility of ever reconstructing bacterial phylogeny. WebbThree-domain system. A phylogenetic tree based on rRNA data, emphasizing the separation of bacteria, archaea, and eukaryotes, as proposed by Carl Woese, George E. Fox et al. in 1990 [1] The three-domain system is a biological classification introduced by Carl Woese, Otto Kandler, and Mark Wheelis in 1990 [2] [1] that divides cellular life forms ...
