New World monkeys evolved from South and Middle America.

Explanation:

Evidence of Evolution
The evolution of New World monkeys is supported by various lines of evidence, including fossil records and genetic studies.

Fossil Records
Fossil records provide important evidence for the evolutionary history of New World monkeys. Fossils of early primates resembling New World monkeys have been found in South America, suggesting that this is their place of origin. These fossils date back to approximately 25 million years ago, indicating that New World monkeys have a long evolutionary history in South America.

Geographical Distribution
The current geographical distribution of New World monkeys also supports the idea that they evolved in South and Middle America. These monkeys are found in Central and South America, including countries such as Brazil, Peru, and Mexico. Their absence in Africa, Asia, and other parts of the world suggests that their evolutionary origin is specific to the Americas.

Genetic Studies
Genetic studies have further confirmed the evolutionary relationship between New World monkeys and their origin in South and Middle America. By comparing the DNA of different primate species, scientists have been able to trace the evolutionary relationships and divergence times. These studies have consistently shown that New World monkeys are more closely related to each other than they are to Old World monkeys or apes, further supporting their independent evolution in the Americas.

Conclusion
In conclusion, the evidence from fossil records, geographical distribution, and genetic studies all point to the fact that New World monkeys evolved from South and Middle America. The presence of early primate fossils in South America, the exclusive distribution of New World monkeys in the Americas, and the genetic similarities among New World monkey species all support this conclusion.
