ANTH 102 Study Guide - Midterm Guide: Aegyptopithecus, Sivapithecus, Ape
Study guide question: Earliest primates 60-55 mya,
earliest Anthropoids in the Fayum 34 mya
(Aegyptopithecus), Miocene Hominoid radiation, natural
selection and the evolution and expansion of new species
(Proconsul and Sivapithecus), 10-8 mya gorillas split off,
8-5 mya humans and chimps split, etc.
3. Eocene timeline contribution to primate evolution? What is adaptive
radiation? Who was Aegyptopithecus? What is Preconsul?
- Earliest primates 60-55 mya at start of Eocene
- About 55 mya
- abrupt warming that caused mass extinction
- Opens up new niches in environment=
- Allows mammals to begin great adaptive radiation into a variety of species
including earliest primates..
- Over 50 prosimians fossil fond in Africa North America Europe and Asia
where the warm wet conditions sustained rainforests.
- Near end of Eocene temperature-drop, form ice cap over previously
forested Antactica
- Marked reduction in territory for primates
- Also = lower sea levels
- Allows for migration
- How primates got to N. America

(for hanging/ suspending in trees. ) Has some features of apes and some of old world monkeys.
