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:
a. this primate exhibits a derived trait for an enhanced sense of smell, since this trait is
not commonly observed in mammal species.
b. this is a species of anthropoid because it has an increased reliance on vision.
c. this primate must be a species of prosimian, as that suborder of primates still relies
heavily on the sense of smell for many aspects of daily life.

The forces of evolution include:
a. gene flow, mutations, chromosomes, and genes.

The Multiregional Continuity hypothesis supposes that:

replacing archaic Homo sapiens populations.

Two types of australopithecines were using two different types of locomotion in East
Africa:
a. one was a quadruped and the other a leaper.
b. one was a clinger and the other a climber.
c. one was a knuckle walker and the other a quadruped.
d. one was a climber and the other a biped.
Polygynous:
a. means "many marriages."
b. means "many offspring."
c. refers to a social group that includes one female and several males.
d. refers to a social group that includes one adult male, several adult females, and their
offspring.
Most of the fossils discovered in Africa come from the eastern and western parts of the
continent. Why is this?
a. More populations of species lived in these areas and nowhere else.
b. Only these areas were conducive to sustaining life.
c. These areas provided better preservation.

primate order; the global warming that is taking place today will likely have negative
impacts for humans, such as:
a. changes in crop production as a result of decreased precipitation.
b. extinction of certain species unrelated to habitat loss.
c. lower sea levels, resulting in the addition of coastal lands on multiple continents.
d. none of the above

c. bonding between individuals of the same rank only, picking through the skin and hair
of another individual.
d. bonding between two members of a social group, calming or appeasing the primate
being groomed if he or she has a higher dominance.
