What is the dental pattern of Old World higher primates?
In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 18.104.22.168. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula. All Old World monkeys, apes, and humans share this 22.214.171.124 dental formula.

What is the Cladistic approach to Primate classification based on?
The cladistic approach to primate classification is: strepsirhines and haplorphines. The cladistic primate classification includes: evolutionary relationships that are based on shared characteristics including physical traits, genetics, and behavior.
Are humans Haplorhines?
GEOGRAPHICAL LINEAGES OF HAPLORHINES
Modern haplorhines are divided into three infraorders: the Platyrrhini, the New World Monkeys; the Catarrhini, the Old World Monkeys, apes and humans; the Tarsiiformes, the tarsiers. … While monkeys and apes are tropical or subtropical animals, humans live in all regions of the world.
Are Gibbons New World monkeys?
Ape, (superfamily Hominoidea), any tailless primate of the families Hylobatidae (gibbons) and Hominidae (chimpanzees, bonobos, orangutans, gorillas, and human beings). Apes are found in the tropical forests of western and central Africa and Southeast Asia.
Are monkeys territorial?
In some forest living primates, contact between groups of the same species is in the form of a specialized territorial defense behavior. Instead of avoiding each other, groups actively converge near their common territorial border and make hostile displays.
Why do primates have an enhanced sense of vision?
Primates’ enhanced vision stems from two developments in the order’s evolutionary history. First, very early in primate evolution, the eyes rotated forward to the front of the head. As a result, the two fields of vision overlap, providing the primate with depth perception. Second, color vision evolved.

Is a tarsier a Strepsirrhine?
Classification. The phylogenetic position of extant tarsiers within the order Primates has been debated for much of the 20th century, and tarsiers have alternately been classified with strepsirrhine primates in the suborder Prosimii, or as the sister group to the simians (Anthropoidea) in the infraorder Haplorrhini.
What are the smallest new world anthropoids?
Living New World monkeys are the smallest anthropoid primates, ranging across a span from less than 1 kg to approximately 10 kg.
Which of the following are prosimians?
Prosimians are a group of primates that includes all living and extinct strepsirrhines (lemurs, lorisoids, and adapiforms), as well as the haplorhine tarsiers and their extinct relatives, the omomyiforms, i.e. all primates excluding the simians.
