Question 16

In class, your professor shows you the skulls of three mammals.In one, the eye would be fully enclosed by bone.In the second, there is a bony circle around where the eye goes, but it is open in the back.In the third, the place where the eye would be is not encircled by bone at all.This suggests to you that

Accepted Answer

A)   the third one is an anthropoid primate, because an organism with a highly developed sense of vision needs more room to move the eyes around.
B)   the second one, with the bony bar around the eye, is probably not a primate.
C)   the first one is an anthropoid primate; the fully enclosed orbit is probably beneficial in an organism that relies heavily on vision.
D)   all three species are probably nocturnal; otherwise, it would be impossible to find evidence of eyes given only the skull.

Question 17

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

Accepted Answer

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.
