Is a category that includes monkeys apes and other primates as well as our fossil ancestors?

Near-human is a category that includes monkeys, apes, and the other primates as well as our fossil ancestors. The primary interest of most biological anthropologists today is human evolution–they want to learn how our ancestors changed through time to become what we are today.

Are Old World monkeys related to apes?

Old World monkeys all belong to one family, Cercopithecidae, which is related to apes and humans, and together they are classified as catarrhines (meaning “downward-nosed” in Latin). The New World monkeys are the platyrrhines (“flat-nosed”), a group comprising five families.

Are Old World monkeys more closely related to New World monkeys or apes?

Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae /ˌsɜːrkoʊpɪˈθɛsɪdiː/. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago.

What is the difference between Old World monkeys and New World monkeys?

Another exception is the spider and howler monkeys— New World species with nails like Old World monkeys (2). New World monkeys are also flat-nosed (platyrrhine) with nostrils further apart, while Old World monkeys have nostrils closer together and a nose which faces down (catarrhine) (2).

Apes share a common ancestor with Old World Monkeys. But that Common Ancestor itself descended from an earlier shared common ancestor with New World Monkeys, which means that it too was a monkey. So it’s both. Apes evolved from monkeys, and share a monkey common ancestor with some living monkeys today.

How old are monkeys in the Old World?

Fossils Indicate Common Ancestor for Old World Monkeys and Apes. This dating places the discovery in the Oligocene epoch, which extends from about 34 million to 23 million years ago. “Before the discoveries from Rukwa, only three primate genera had been described from all of the late Oligocene, globally,” says Stevens.

Did monkeys and apes split from their common ancestor?

Molecular clocks suggest that Old World monkeys and apes split from their common ancestor 25 million to 30 million years ago. “It’s a confirmation that the molecular-clock studies are decent estimates for what’s going on in geological time,” says Michael Steiper, an anthropologist at Hunter College of the City University of New York.
