Using what you’ve learned about relative limb proportions and primate locomotion, what kind
of locomotion does the macaque have vs. the chimpanzee
in the trees
? Do the limb
more closely resemble the macaque or the chimpanzee?
Is this what you would expect in a hominoid ancestor based on the style of arboreal
locomotion in modern hominoids? Why?
Station 5: The Miocene through Pleistocene – Fossil Apes in Asia (1 pt.)
During the Miocene, a dispersal of larger-bodied, thick-enameled apes from Africa into Eurasia
formed the basis of a radiation thought to produce both the ancestor to modern orangutans and
the largest primate to ever live:
. Use the fossil material and handouts at this
station to answer the following questions about members of this radiation.
(15-9 mya) is an ape fossil found in Pakistan and northwestern India that is
thought to be an early relative of orangutans. Describe
