The prosimians were once a group considered a suborder of the primate [[Order (biology)|order]] (suborder '''Prosimii''' - Gr. ''pro'', before, + Latin ''simius/simia'', ape), which was named in 1811 by [[Johann Karl Wilhelm Illiger]]. They have been shown, however, to be paraphyletic - that is, their most recent common ancestor was a prosimian but it has some non-prosimian descendants (i.e. monkeys and apes). This relationship is shown by the ranks (prosimians in '''bold''') in the list below of the current primate classification between the order and [[Taxonomic rank|infraorder]] level. The term "prosimian" is considered taxonomically obsolete,<ref>{{Cite journal | last1 = Groves | first1 = C.
