It was realized by the biologists during recent past (1970s-80s) that the classification based on genetic characteristics (rather than phenotypic ones) with respect to evolutionary relatedness (phylogeny) of organisms may prove more stable and predictable. In 1987, Carl Woese of University of Illinois (USA) summarized ten years of work and proposed a phylogenetic classification system for prokaryotic species based on [...]
