What is one of the key indicators of primates’ adaptability? Haplorhines, monkeys and apes, are distinguished from strepsirhines by their facial features, the structure of their skulls and dentition and the placenta. 3. fingernails and claws. Haplorhines: 1. bigger brains. Divergence between strepsirrhines (lemurs and lorises) and haplorhines (tarsiers and anthropoids) is correlated with intense volcanic activity on the Lebombo Monocline in Africa about 180 million years ago. Collectively they are referred to as strepsirrhines. 2. fully enclosed eye orbits. 2. tooth comb. Haplorhini (the haplorhines or the "dry-nosed" primates, the Greek name means "simple-nosed") is a suborder of primates containing the tarsiers and the simians (Simiiformes or anthropoids), as sister of the Strepsirrhini ("moist-nosed"). True. The name is sometimes spelled Haplorrhini. There are three major surviving radiations – lemurs and lorises (strepsirhines) and Old World monkeys and apes (catarrhines) occur in Africa and Asia, and New World monkeys (platyrrhines) live in Central and South America – but many species are now threatened with extinction and the fourth radiation consists of only one genus, the tarsiers of eastern Asia. Soon after the initial split between the toothcombed strepsirrhines and the haplorhines, there was a divergence between the lemurs and the Afro …
Strepsirhines have moist noses; haplorhines have simple, dry noses.

ringtailed lemurs have undergone convergent social-cognitive evolution with haplorhines, possibly as an adaptation for living in the largest and most complex social groups among strepsirrhines. Lemurs are found in a wide range of ecologic niches in Madagascar, including the low to high altitude tropical rain forests on the east coast, the dry deciduous forests of the west, and the spiny deserts of the south. Ringtailed lemurs were again the only species that looked up more frequently when an experimenter gazed into space than when an experimenter gazed forward (although at relatively low frequencies). Order Primates Suborder Strepsirhini Haplorhini o Strepsirhini Lemurs Lorises o. Haplorhini (the haplorhines or the "dry-nosed" primates; the Greek name means "simple-nosed") is a suborder of primates containing the tarsiers and the simians (Simiiformes or anthropoids), as sister of the Strepsirrhini ("moist-nosed").

Primates have reduced reliance on smell, which is reflected in their smaller snouts, as compared with other mammals. Traditionally primates are divided into two groups- Prosimians which include lemurs, lorises, and tarsiers and Anthropoids which include monkeys, apes, and humans. Haplorhines show a trend towards flattened faces with forward facing eyes. Notes . Primate - Primate - Classification: Traditionally, the order Primates was divided into Prosimii (the primitive primates: lemurs, lorises, and tarsiers) and Anthropoidea (the bigger-brained monkeys and apes, including humans). The name haplorhine means simple nose.
2011 The Association for the Study of Animal Behaviour. The name is sometimes spelled Haplorrhini. However more recent classifications divides them this way – the suborder Strepsirhini includes lemurs, lorises, and bush babies and the suborder Haplorhini includes monkeys, apes, and tarsiers. Strepsirhines. This trend is linked to an increasing reliance on vision and a decreasing reliance on smell. They live in a wide range of habitats. Results are discussed in terms of lemur cognitive evolution as well as the social intelligence hypothesis. The lower primates or strepsirhines (suborder Strepsirhini) include lemurs, bush babies, lorises; the higher primates or haplorhines (suborder Haplorhini) include the tarsiers, Old and New World monkeys, apes and humans.

Strepsirrhini or Strepsirhini (/ ˌ s t r ɛ p s ə ˈ r aɪ n i / (); STREP-sə-RY-nee) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. 4. large olfactory bulb.
