Implications of Enamel Prism Patterns for the Origin of the New World Monkeys
The Platyrrhini as well as the Catarrhini were independently derived from Laurasian Paleogene primates, presumably an omomyid lower primate. Therefore, the close resemblance of New and Old World monkeys can be interpreted or explained as a result of convergence and/or parallelism from a lower primate ancestor.
The Platyrrhini and the Catarrhini were derived from a common ancestral anthropoid stock probably African in origin with the dispersal of the platyrrhine ancestors occurring through direct faunal interchange (rafting) between the southern continents across the South Atlantic Ocean.
