In your primate anatomy lab you are shown the mandible (lower jawbone) of a species
of primate. While looking at the teeth you notice a large space between the canine and
first premolar. In your lab book you note that this:
a. is likely the lower jaw of a human, due to the potential presence of a canine-premolar
honing complex.
b. may be a species of Old World monkey or ape, as the space in the teeth of the
mandible suggests the presence of a canine-premolar honing complex.
c. is likely the lower jaw of a human, given the presence of a nonhoning chewing
complex.
d. may be a species of Old World monkey or ape, as the space in the teeth suggests the
presence of a nonhoning chewing complex.
Vocalizations enable primates to:
a. communicate as humans do.
b. solve distressing situations among primate groups.
c. name resources and monitor the social group.
d. communicate, but only between members of the same hierarchy.
