  15. Primate Taxonomy

  16. Strepsirhini vs. Haplorhini

  17. Strepsirhini (Prosimians) • Strepsirhini • Most primitive of all primates • Note: Primitive = “least derived”, most similar to earlier mammalian ancestors • Ancestral Characteristics • ___________________________________ • ____________________________________ • Geographical Locations – Madagascar, Africa, Asia

  18. Haplorhini (Anthropoids) • In comparison to stepsirhinis, anthropoids share: • _________________________________

  19. Haplorhini (Anthropoids) • In comparison to stepsirhinis, anthropoids share: • ____________________________________

  20. Haplorhini (Anthropoids) • In comparison to stepsirhinis, anthropoids share: • ___________________________________

  21. Haplorhini (Anthropoids) • In comparison to stepsirhinis, anthropoids share: • reproductive/gestational/childrearing differences • ___________________of a grooming claw

  22. Haplorhini (Anthropoids) • Who are the haplorhines? • New World Monkeys • Old World Monkeys • Hominoids (apes and humans) Differences exist between the haplorhines

  23. New World Monkeys - Platyrrhines • Wide range in diet • All are arboreal • ________________ • Some with prehensile tails, some without prehensile tails • What do you think a prehensile tail is?

  24. Old World Monkeys – Catarrhines • Tails (not prehensile) • _________= Ischial Callosities • Rest in a ___________ • Some species have ______________ • What do you these are?
