Document Summary
The strepsirhines: = prosimians w/ the exception of one prosimian primate, the tarsier- it is a haplorhine. Reliance on olfaction, nocturnality, lack of complex social patterns, incisor teeth that form tooth comb for grooming, specialized claw toes for grooming. Lemurs- found only on madagascar; includes true lemurs, dwarf lemurs, sifakas and indri, and the aye-aye. As madagascar drifted slowly away from africa, the primitive primates stranded there began to evolve w/out gene flow from other primates. Many extinct forms which we know about due to subfossils- found as bones rather than fossils due to recent date of animals" disappearance. Dwarf lemurs- small, dull-colored insect- and fruit-eaters; nocturnal; solitary. True lemurs- diurnal and social, living in groups; among many, females are dominant to males, ex: ring-tailed lemur. Indri noted for its monogamous social system; its loud, hanting call; and its diet of leaves. Aye-aye- nocturnal and largely solitary; feeds on bird eggs, fruit, insect larvae.
