Journal of Vision - The evolution of eye shape at the origin of Primates and Anthropoidea, by Ross, Kirk, and Heesy
Primates are distinguished from many other mammals by a suite of features of the visual system, among them convergent orbits, postorbital bars, increased density of photoreceptors and ganglion cells in the central retina, and increased representation of the central retina in the visual structures of the brain.

This measure actually understates the degree of visual specialization, because anthropoids have a strongly disproportionate number of ganglion P-cells which register color and shape, as compared to the ganglion M-cells, which register contrast and movement.

 Russell Ciochon -- Fossil Ancestors of Burma
They are sometimes called the Anthropoidea, or humanlike primates.
The Anthropoidea, or higher primates, are shown in orange; the Prosimii, or lower primates, which comprise all other primates, form a less unified group (yellow).
Some early prosimians, perhaps a group related to lemurs and lorises, gave rise to the Anthropoidea.

 Human Evolution - MSN Encarta
Tarsiers have traditionally been grouped with prosimians, but many scientists now recognize that tarsiers, monkeys, and apes share some distinct traits, and group the three together.
Monkeys, apes, and humans—who share many traits not found in other primates—together make up the suborder Anthropoidea.
Apes and humans together make up the superfamily Hominoidea, a grouping that emphasizes the close relationship among the species of these two groups.

 Ch5. Introduction to the Primates
However, different divisions of the Primate order are produced by different systematic approaches--namely, the differential weighting of overall similarity versus phylogeny.
Two taxonomic arrangements are generally used today--one based on the traditional division between Prosimii and Anthropoidea, and a more recent one that divides groups into the Strepsirhini and Haplorhini.
The difference between these two taxonomies is that the Tarsiiformes have been moved from the traditional suborder of Prosimii into the Anthropoidea.

There are at least 145 living species of the suborder Anthropoidea
There are two distinct infraorders of Anthropoidea that have been evolving independent of each other for at least 30,000,000 years.
These two diverse groups of species can be distinguished from each other most easily based on the form of their noses and by the number of specific types of teeth.

  Primate Genomics: The Search for Genic Changes that Shaped being Human
Brain capacity is significantly larger in the Miocene fossil primates of suborder Anthropoidea than in the earlier Eocene fossil primates (Fleagle, 1988; Martin, 1990).
Also, among living primates, the neocortical portions of the brain are much larger in simian primates (the living platyrrhines and catarrhines of Anthropoidea) than in non-simian primates (the tarsiers and the lemuriform and loriform strepsirhines).
The analysis is straight forward with coding sequences because here one compares the pattern of nonsynonymous rate changes to the pattern of synonymous rate changes, with any slowdown due to purifying selection being much more evident for nonsynonymous (amino acid) changes than for synonymous (silent) changes.

One subset of Haplorhini is Anthropoidea, (monkeys) primates with binocular vision, a pendulous penis, a well-developed caecum, a large brain, two pectoral mammae, and a tendancy toward bipedalism.
All anthropoids have lost the ability to synthesize either vitamin D3 or vitamin C, and need to supplement both of these in their diet or they'll succumb to a condition of malnutrition commonly known as scurvy.
One subset of Anthropoidea is Catarrhini, (Old World monkeys) with elevated intelligence, downturned nostrils, flat fingernails, and without prehensile tails.

 IngentaConnect Primate Phylogeny: Morphological vs Molecular Results   (Site not responding. Last check: )
In one hypothesis, tarsiers are closely related to lemurs and lorises, and thus Primates is divided into Prosimii [lorises, lemurs, and tarsiers] and Anthropoidea [Platyrrhini and Catarrhini, i.e., monkeys, apes, and humans].
Two additional alternatives are that Tarsius is a sister group to the clade embracing lorises + lemurs and Anthropoidea and that in which all three lineages (Tarsius, lorises + lemurs, and Anthropoidea) form a polychotomy.
In another hypothesis, tarsiers are closely related to anthropoids, giving these two branches: Strepsirhini [lemurs, lorises] and Haplorhini [tarsiers and Anthropoidea (Platyrrhini, the New World monkeys, and Catarrhini, Old World monkeys and Hominoidea)].

Because of the potentially destructive effects of radicals, nearly all animals evolved to manufacture large amounts endogenous ascorbate (vitamin C), a powerful scavenger of hydroxyl radicals.
The role of radicals in fostering the evolution of Anthropoidea and H. sapiens is supported by their role in creating mutations in general.
Thus, although antioxidants have a beneficial effect in the protection against aging, care should be taken to test each specific antioxidant in its potential protective effect against age-associated impairment in molecular, metabolic, and physiological functions.

Phylogenetic analyses using maximum likelihood on nucleotides and amino acids robustly support the monophyly of primates, Strepsirrhini, Lemuriformes, Lorisiformes, Anthropoidea, Catarrhini, and Platyrrhini.
It is interesting to note that 1) Tarsiidae grouped with Anthropoidea, and the support for this node depends on the molecular characters considered; 2) Cheirogaleidae grouped within Lemuriformes; and 3) Daubentonia was the sister group of all other Lemuriformes.
