Well one difference would be that Old World Monkeys have more opposable thumbs than New World Monkeys (basically, it's the main difference). For more information, try clicking the related link. Hope this helped~
Apes are more closely related to Old World Monkeys.
Old World generally refers to monkeys of Africa and Asia; New World, to monkeys of the Americas. In Old World monkeys, the nostrils face downward and are narrow. New World monkeys have round nostrils facing to the side. The dental formula of the larger New World monkeys includes 3 premolars. Old World monkeys have 2.
Chimpanzees are not New World monkeys. New World monkeys are found in the Americas. Old World monkeys are found in Asia and Africa.
There are 2 major classifications of monkeys. There are Old World and New World Primates. Marmosets and squirrel monkeys are new world primates. Old world primates are roloway and mandrill monkeys.
New world monkeys would be more likely found
Old World monkeys live in Africa and Asia. When the Americas were discovered, people called the western hemisphere the New World. Europe and the rest of the known lands were called the Old World. That is why monkeys of the Americas are called New World monkeys and those from Africa and Asia are called Old World monkeys.
There are many, many different species and subspecies of monkeys. Each has its own unique markings. 264 species of monkeys are known. Monkeys are divided into two groups, old world (cercopithecoid) and new world (platyrrhine). They are quite distinct from each other. The old world monkeys are closely related to apes, while new world monkeys are very distant from apes and other monkeys.
Lemurs are NOT monkeys (so they cannot be New World nor Old World monkeys); they are prosimians. Prosimians are found in the Old World.
New World Monkeys. Many New World monkeys in the family Atelidae, which includes howler monkeys, spider monkeys and woolly monkeys, have grasping tails often with a bare tactile pad. This is in contrast with their distant Old World monkey cousins who do not have prehensile tails.
the answer is the 'DRILL' related to the baboon Mandrill.
The four major groups of primates are prosimians (such as lemurs and tarsiers), New World monkeys (such as spider monkeys and howler monkeys), Old World monkeys (such as baboons and macaques), and apes (such as gorillas and orangutans).
If you're really just talking about monkeys then you have to start with old world or new world monkey families such as Cebidae (new world capuchin type) or Callitrichidae (new world tamarans and marmosets) or Cercopithidae (old world monkeys) then they break down further from there.
