Was there a common ancestor for both Old and New World monkeys? Of course!
The common ancestor between the two was a Trichromatic primate. Evolution occurred during the split of the continents. This was about seventy-eight billion years ago. The split between the continents is a reasonable hypothesis because it changed where some primates lived and moved them to different environments. Basically, it was the survival of the fittest when the continents split (Evo-Ed: Integrative Cases in Evolution Education. (n.d.).
Some primates that are here today are Capuchin monkeys. They live in Central and South America and have Dichromatic vision. Another example of a present species of a primate is the Howler Monkey. They too, live in Central
