High Quality Content by WIKIPEDIA articles! The haplorrhines, the "dry-nosed" primates (the Greek name means "simple-nosed"), are members of the Haplorrhini clade: the prosimian tarsiers and all of the true simians. The simians are the catarrhines (Old World monkeys and apes, including humans) and the platyrrhines (New World monkeys). The omomyids are an extinct group of prosimians, believed to be more closely related to the tarsiers than to any strepsirrhines, and are considered the most primitive haplorrhines. The Darwinius specimen from Messel has been suggested as the earliest known true haplorrhine. Haplorrhines are considered to be less primitive than the strepsirrhine "wet-nosed" primates (whose Greek name means "curved nose"), the other suborder of primates from which they parted in evolution some 63 million years ago. The haplorrhines, including tarsiers, have all lost the function of the terminal enzyme which manufactures vitamin C, while the strepsirrhine prosimians, like most other orders of mammals, have retained this enzyme and the ability to manufacture vitamin C.
