carbohydrates in tail; eat resins, gums, insects; related to Galagidae and Lorisidae on basis of carotid circulation (having an ascending pharyngeal artery) Galagidae: bushbabies; sub-saharan Africa; nocturnal; elongate ankle, leaping; at resins, gums, insects; derived in having pneumaticized mastoid region. Lorisidae: lorises; 2 genera in sub-saharan Africa, 2 in southeast Asia; nocturnal; lack tail; reduced second digit on hand; cautious climbers; eat noxious insects.

2 Tarsius : islands of southeast Asia; nocturnal; only totally proteinivous primate (will eat vertebrates larger than itself, including neurotoxic snakes); only mammal whose eyeball is larger than its brain; center of debate about being more closely related to other prosimians (it has a grooming claw and reduced toothcomb) or anthropoids (it lacks a tapetum and rhinarium); only primate with (primitive) bicornuate uterus to develop hemorchorial placentation. Fossil Prosimians: Adapidae: middle-late Eocene, Europe; traditionally thought of as "fossil lemurs"; probably related to only some Malagasy prosimians Notharctidae: early-middle Eocene, N. America; traditionally thought of as "fossil lemurs"; probably sister taxon of extant prosimians Tarsiiformes: three groups traditionally recognized, Microchoerine (middle-late Eocene, Europe), Omomyidae and Anaptomorphidae (early Eocene-late Miocene?, N. America and Europe); probably not closely related to Tarsius ; look like bushbabies in skull and bushbabies and mouse lemurs in ankel bones. Extant Anthropoids: derived in having early fusion of metopic (frontal) suture and mandibular symphysis; nails on all digits; reduction to 3 premolars in each quadrant of the jaw; partial postorbital closure; hemochorial placentation; simplex uterus; partial fusion of upper lip; lack of rhinarium. Platyrrhini: broad-nosed primates; New World monkeys Catarrhini: narrow-nosed primates: Old World monkeys and hominoids

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
