Document Summary
Strepsirrhines (lemuriformes and lorisiformes) are a monophyletic suborder of primates. Tarsiers are grouped with platyrrhines (new world monkeys) and catarrhines (old world monkeys, apes and humans) ==== haplorrhines. Streps and tarsiers make up a third of living primates. Lemurs are biggest group of streps, endemic to madagascar. Very diverse species, expected to have come from africa and then diverged. 2 primary clades are distinguished from lemurs at family level. Bush babies or galagos are most diverse members of the group. Sexual differences in lorsiforms and tarsiers are modest, males slightly heavier. Streps and tarsiers almost completely arboreal, except some lemurs. Brain size is also 1/3 of any anthropoid. Small brain size may reflect adaptations of reduced demands of their less complex social lives. Tarsiers are faunivorous- eat arthropods and small vertebrates. But some lemurs eat only tree gum and sap or leaves buds, bamboo and flowers. Basal metabolic rate scales to body weight in mammals.
