The Proteobacteria is not monophyletic in this phylogram, but this may be erroneous given the large amount of literature in favour of basal Acidobacteria. Contrary to 16S trees, the deepest branching clade is the Firmicutes . Nevertheless, the last common ancestor was between Bacteria and Archaea Eukarya. See also Branch ... more details

Unreferenced date October 2010 Human taxonomy is the classification of the species Homo sapiens Latin wise man , or modern human. Homo genus Homo is the human genus , which also includes Neanderthal s and many other extinct species of hominid H. sapiens is the only surviving species of the genus Homo . Extinct Homo species are known as archaic humans. Modern humans are the subspecies Human Homo sapiens sapiens , differentiated from a direct ancestor, Homo sapiens idaltu . Prior to the current scientific classification of humans, philosophers and scientists have made various attempts to classify humans. They offered various definitions of the human being and various schemes for classifying types of humans. Biologists once classified races as subspecies, but today scientists question even the concept of race itself. Certain issues in human taxonomy remain topics of debate today. Extended scientific classification The modern scientific classification of the human species contains many sub and super sections each one being, ideally, a clade which have been interpolated between the seven traditional taxon Linnaean taxonomic ranks . Humans are not only the sole surviving representatives of the genus Homo but also the only surviving representatives of the subtribe Hominina, which includes Australopithecus and other more anthropomorphic hominids. Species believed to be ancestors are listed within higher taxa.
