What animal did Catarrhines evolve from?

The earliest known catarrhine is Kamoyapithecus from uppermost Oligocene at Eragaleit in the northern Kenya Rift Valley, dated to 24 million years ago. Its ancestry is thought to be species related to Aegyptopithecus, Propliopithecus, and Parapithecus from the Faiyum depression, at around 35 million years ago.

Apes and humans differ from all of the other primates in that they lack external tails. ... In addition, the lower molar teeth of apes and humans have five cusps, or raised points, on their grinding surfaces. This is known as a Y-5 pattern because the area between the cusps roughly is in the shape of the letter Y.

What is the oldest primate group?

A new study published Feb. 24 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. A team of 10 researchers from across the U.S. analyzed several fossils of Purgatorius, the oldest genus in a group of the earliest-known primates called plesiadapiforms.

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

Monkeys are arranged into two main groups: Old World and New World. ... New World monkeys have broad noses with a wide septum separating outwardly directed nostrils, whereas Old World monkeys have narrow noses with a thin septum and downward-facing nostrils, as do apes and humans.

Are humans catarrhines?

Catarrhines include gibbons, orangutans, gorillas, chimpanzees, and humans. Two superfamilies that make up the parvorder Catarrhini are Cercopithecoidea (Old World monkeys) and Hominoidea (apes).

Are tarsiers catarrhines?

Haplorrhines are split into three groups: 1) the catarrhines, old world monkeys, apes, and humans; 2) the platyrrhines, new world (South American) monkeys, and 3) tarsiers. ... Catarrhines have narrow downward facing nostrils, while platyrrhines have broad, flat, sideways facing nostrils.

Most marmosets and tamarins have a head-and-body length of 7-12 in (17-30 cm), plus a tail about 3 in (7.5 cm) longer than that.

Did New World monkeys evolve from Old World monkeys?

The NWMs diverged from the Old World monkeys and apes (Catarrhini) around 40 million years ago (Perelman et al. 2011). Ancestral species are thought to have migrated to the Americas on rafts of vegetation or via island hopping (Fleagle 2013).

Are owl monkeys New World?

A New World monkey is any member of the primate clade Platyrrhini, comprised of four Central and South America families: Cebidae (marmosets, capuchins, squirrel monkeys, tamarins), Aotidae (night or owl monkeys), Pitheciidae (titis, sakis, uakaris), and Atelidae (howler, spider, and woolly monkeys).

They share their habitats with prosimians and apes, so there're a lot of niches lying around which aren't filled by the old world monkeys since some other primate filled it first.

Where did catarrhines originate?

Abstract. The catarrhines are a group of anthropoid primates comprising the Old World monkeys, apes, and humans. The earliest record of fossil catarrhines, the propliopithecoids, comes from the Early Oligocene of Egypt (29–32 million years ago (mya)).
