Your sister calls you crying because she just hit an animal with her car, and she thinks it was a ring-tailed lemur. You calm her down by saying that:
lemurs exist in the wild only in Madagascar, so she probably hit a raccoon

none of those monkeys have prehensile tails

in the superfamily Hominoidea

close together and face downward

their forward facing eyes and color vision
Modern primates are characterized by arboreal adaptations, including:
Arboreal adaptation is:
adaptation to life in the trees

an individual that is fully quadrupedal, such as a dog

-They have large, bulbous eyes
-They have only two lower incisors
-They have elongated tarsals to leap
-They are classified as haplorhines
What is one of the key indicators of primates' adaptability?
They live in a wide range of habitats
Humans have ______ canine teeth, whereas monkeys and apes have ______ canines.
Which features belong to primates over other mammals?
-Relatively longer periods of maternal investment
-Longer period of time between births
-Longer growth and development periods
-Tend to give birth to only 1 offspring at a time
Which part of the dentition is the "honing complex"?
The canines and the lower third premolar
Anthropologists study primates because:
Primates and humans share a common ancestry
Which of the following statements are INCORRECT?
-There are more than 200 primate species living today
-Tarsiers present some classification problems, but are grouped with the haplorhines
-The haplorhines are considered the lesser, or lower, primates
-Apes and humans are considered higher primates
(Tarsiers present some classification problems, but are grouped with the haplorhines) WRONG)
Visual differences between primates and other animals include:
Overlapping vision fields
Orangutans, Chimpanzees, Gorillas
The teeth of Old World monkeys and apes differ in that:
apes have a Y-5 pattern of cusps, whereas Old World monkeys have a bilophodont pattern
One of your friends is originally from Ecuador. When he was a kid, he would sneak into the forest and watch howler monkeys. On one of these trips, though, he insists that he and his friends found a human skull. As he describes it, you realize it was not human because:
the foramen magnum was not llocated at the bottom of the skull
On a visit to the zoo, you overhear a teacher telling a young student that the chimpanzees climb and swing on branches because their:
good sense of touch lets them grip trees
Among all primates humans have:
the most elaborate connections between different regions of the brain
Primates have long growth and development periods because:
