The simians (infraorder Simiiformes) are the "higher primates" familiar to most people: the monkeys and the apes, including humans. The Eocene epoch (558 ± 02 - 339 ± 01 Ma) is a major division of the Geologic timescale and the second epoch of the Palaeogene period in The Lar Gibbon ( Hylobates lar) also known as the White-handed Gibbon, is a Primate in the Hylobatidae or Gibbon family Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands A primate is a member of the biological order Primates ( Latin: "prime first rank" the group that contains Lemurs the Aye-aye The haplorrhines, the "dry-nosed" primates (the Greek name means "simple-nosed" are members of the Haplorrhini clade: the Prosimian Ernst Heinrich Philipp August Haeckel ( February 16, 1834 — August 9, 1919)also written von Haeckel, was an eminent German In Biological classification, family ( Latin The Cebidae form one of the four families of New World monkeys now recognised The Night monkeys, also known as the Owl monkeys or Douroucoulis, are the members of the Genus Aotus of New World monkeys The Pitheciidae are one of the four families of New World monkeys now recognised The Atelidae are one of the four families of New World monkeys now recognised The Old World monkeys or Cercopithecidae are a group of Primates falling in the Superfamily Cercopithecoidea in the Clade Gibbons are the small Apes in the family Hylobatidae.

Classification and evolution

The simians are split into three groups. The New World monkeys in Platyrrhini parvorder split from the simian line about 40 million years ago (mya), leaving the Catarrhini parvorder occupying the Old World. The New World monkeys are the four families of Primates that are found in Central and South America: Cebidae, Aotidae, Pitheciidae The New World monkeys are the four families of Primates that are found in Central and South America: Cebidae, Aotidae, Pitheciidae In Astronomy, Geology, and Paleontology, mya or " mya " is an abbreviation for "million years ago". Catarrhini is a Parvorder of the Primates, one of the three major divisions of the Suborder Haplorrhini. This group split about 25 mya between the Old World monkeys and the apes. Earlier classifications split the primates into two large groups: the "Prosimii" (strepsirrhines and tarsiers) and the simians in "Anthropoidea"(an'thro-poy'de-a)(Gr. The Clade Strepsirrhini is one of the two Suborders of Primates One of the most distinguishing characteristic of these 118 species is their Wet Tarsiers are Prosimian Primates of the genus Tarsius, a Monotypic genus in the family Tarsiidae, which is itself the anthropos, man).
