Its common ancestor with the platyrrhine monkeys would also be considered a monkey.
2.
Post-cranially, pliopithecoids had an interesting mix of platyrrhine and catarrhine traits.
3.
Note that the RBP3 intron 1 has also been used to investigate the platyrrhine primates phylogenetics.
4.
:: Yes, the platyrrhine monkeys originated in South America 40 million y / a.
5.
The technical distinction between the New World platyrrhines and Old World catarrhines is the shape of their noses.
6.
In contrast, platyrrhines have only a single, polymorphic X chromosome M / L opsin gene locus.
7.
This taxon was traditionally thought to be a primitive lineage, from which all the larger-bodied platyrrhines evolved.
8.
The premaxilla is short, giving the appearance of a small, not especially prognathic face relative to other platyrrhines.
9.
This hypothesis proposes that this crossing-over event occurred in a heterozygous catarrhine female sometime after the platyrrhine / catarrhine divergence.
10.
Like catarrhines, howler monkeys ( a family of platyrrhines ) show routine trichromatism that has been traced to an evolutionarily recent gene duplication.
