Prosimians are a grouping of mammals defined as being primates, but not monkeys or apes. They include, among others, lemurs, bushbabies, and tarsiers. They are considered to have characteristics that are more primitive than those of monkeys and apes. Prosimians are the only primates native to Madagascar, and are also found in Africa and Asia. With the exception of the tarsiers, all extant prosimians are in the suborder Strepsirrhini. Because tarsiers, as well as some extinct prosimians, share a more recent common ancestor with monkeys and apes than with other prosimians, they belong to a paraphyletic group and not a clade.
