  New World monkey - Wikipedia, the free encyclopedia
The New World monkeys are the four families of primates that are found in Central and South America: the Cebidae, Aotidae, Pitheciidae and Atelidae.
The four families are ranked together as the Platyrrhini parvorder.
The scientific name for New world monkey, Platyrrhini, means "flat nosed", therefore the noses are flatter, with side facing nostrils, compared to the narrow noses of the Old World monkey.

This is a schematic survey of the occurrence of the LH receptor type II mRNA without exon 10 among the primate order.
While the suborder of the prosimians (Strepsirrhini) shows neither CG [24] nor LHR type II, in the second suborder of the anthropoid primates (Haplorrhini), both LHR types with and without exon 10 occur as well as the hormone CG.
The infraorders of the Old World monkeys (Catarrhini) and the great apes revealed LHR type I with exon 10, but exon 10 was absent in the infraorder of the New World monkeys (Platyrrhini), in which species from two out of the three recent families were demonstrated to exhibit LHR type II lacking exon 10 mRNA.

In this study, we analyzed mitochondrial genomes from Cebus (Platyrrhini), Homo, Hylobates, Pan, Pongo (Hominoids), Macaca, Papio (Cercopithecoids), and Tarsius (outgroup) to investigate this matter.
Two distinct methodologies were employed on mitochondrial genes to estimate divergence times: the traditional likelihood ratio test performed in ML analyses of individual and concatenated gene sequences and the recent multigene Bayesian approach.
Our estimate for the origin of New World monkeys is in agreement with the hypothesis of a transatlantic journey from Africa to South America, as suggested by the fossil record.

 New World Monkeys - Primates - Animal Planet
New World Monkeys, or Platyrrhini, differ from Old World Monkeys in their noses.
The scientific name Platyrrhini means "flat nosed" and such monkeys have noses that are flatter, with side-facing nostrils compared to the narrow noses of Old World Monkeys.
Unlike most Old World Monkeys, many of the Platyrrhini primates form monogamous pair bonds and show substantial paternal care of young.

They include many more species, are more widely distributed, and in most areas play a more important ecological role.
Haplorhines are further divided into two major groups, the Platyrrhini and the Catarrhini.
Platyrrhines have flat noses, outwardly directed nasal openings, 3 premolars in upper and lower jaws, anterior upper molars with 3 or 4 major cusps, and are found only in the New World (families Cebidae and Callitrichidae).

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.
The incompatibility between some paleontological and molecular estimates may reflect the incompleteness of the placental fossil record, and/or indicate that the variable IRBP evolutionary rates are not fully accommodated by local molecular clocks.

 Primate Genomics: The Search for Genic Changes that Shaped being Human
The anthropoideans of the middle Eocene epoch (at ~40 Ma) divided into the infraorders Platyrrhini and Catarrhini.
Additional information from the molecular phylogenetic trees produced in recent studies were used in recalculating the estimated ages for taxa within Platyrrhini (Meireles et al., 1999; Chaves et al., 1999) and within Cercopithecidae (Page et al., 1999).
Subgeneric names are used here for any collection of species with an estimated LCA age of 6 Ma or less and with at least some species in the collection having different full generic names in Groves (1993), also in Rowe (1996) who follows Groves in his use of generic names.

Chromosome rearrangements are considered as “rare genomic changes'' and can provide useful markers and even landmarks for reconstructing phylogenies complementary to DNA sequence data and bio-morphological comparisons.
Here, we applied multi-directional chromosome painting to reconstruct the chromosome phylogeny and evolutionary relationships among the New World monkey (Platyrrhini) species Callithrix argentata, Cebuella pygmaea, Saguinus oedipus, Callithrix jacchus and Callimico goeldii.
Various derived chromosomal syntenies are shared by all five species and cytogenetically define Callitrichidae - including Callimico goeldii - as a distinctive group within the Platyrrhini.
