They are also outside the tropical regions of Africa and Asia (Jardine 45). There is a belief that about forty million years ago, there was a significant division among the monkey species. The Old monkeys and the apes were living in the tropics of Africa and Asia, and the New World Monkeys were living in America. Although monkeys appear to have same external appearances, a closer look reveals distinctive and unique differences between the Old World monkeys in the New World (American) monkeys. This paper aims to compare the New World and Old World monkeys.On one hand, the Old World Monkeys are generally larger in size. They have flat fingernails in instead of sharp.
