You are reading a scientific paper regarding the relationships of the anatomical and behavioral characteristics of chimpanzees and their implications for early hominid evolution. You note that the authors refer to human ancestors as hominids. This implies that the researchers are relying on:
a.
cladistic classifications of chimpanzees and humans, as this is most appropriate for their research.
b.
anatomical classifications of chimpanzees and humans, as this is most appropriate when looking at adaptation and anatomy.
c.
genetic classification of chimpanzees and humans, hence their use of the term hominidto describe human ancestors.
d.
both b. and c.
b.
anatomical classifications of chimpanzees and humans, as this is most appropriate when looking at adaptation and anatomy.
In class your professor shows you an MRI scan of a primate brain. The professor points out the relatively large size of the olfactory bulb beneath the frontal lobe. This suggests to you that this: a.
primate exhibits a derived trait for an enhanced sense of smell, since this trait is not commonly observed in mammal species.
b.
is a species of anthropoid because it has an increased reliance on vision.
c.
primate must be a species of prosimian, as that suborder of primates relies heavily on the sense of smell for many aspects of daily life.
d.
species is nocturnal.
c.
primate must be a species of prosimian, as that suborder of primates relies heavily on the sense of smell for many aspects of daily life.
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.
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.
While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to grasp branches while moving throughout the trees in its enclosure. This is most likely a(n):
a.
Old World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet.
b.
lesser ape, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet.
c.
New World monkey, because these are the only monkeys that live in trees.
d.
New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet.
d.
New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet.
A skull with a foramen magnum positioned at the back of the skull belongs to:
a.
an individual that is fully bipedal, such as a human.
b.
an individual that is fully quadrupedal, such as a dog.
c.
an individual that is fully quadrupedal, such as a human.
d.
none of the above (this trait is observed only in prosimians).
b.
an individual that is fully quadrupedal, such as a dog.
