A)tend to swing from branch to branch
B)travel by vertical clinging and leaping
C)move mostly on the ground
D)run and leap along branches

Accepted Answer

D

Question 2

Most living nonhuman primate species are under threat of extinction.

Accepted Answer

According to the International Union for Conservation of Nature (IUCN), more than 60% of primate species are threatened with extinction due to habitat loss, hunting, and other human activities.

Question 3

The strepsirhine infraorder includes __________.
A)lemurs
B)tarsiers
C)monkeys
D)none of these

Accepted Answer

The strepsirhine infraorder includes lemurs.

Question 4

All primates have a fully opposable thumb and hallux.

Accepted Answer

Not all primates have a fully opposable thumb and hallux (big toe); the degree of opposability varies among species. For example, humans have a fully opposable thumb but not a fully opposable hallux, while some primates may lack opposable thumbs entirely.

Question 5

Members of the haplorhine infraorder closely resemble the earliest primates.

Accepted Answer

Members of the haplorhine infraorder, which includes monkeys, apes, and humans, have evolved significantly from the earliest primates and possess more advanced characteristics, such as larger brains and more complex behaviors, distinguishing them from the more primitive features of the earliest primates.

Question 6

Mammals in the __________ group reproduce without a placenta.
A)prototheria
B)eutheria
C)metatheria
D)all of these

Accepted Answer

Metatheria includes marsupials, which reproduce without a placenta. Prototheria (monotremes) and Eutheria (placental mammals) both have different methods of reproduction.

Question 7

About __________ mammal species exist today.
A)400
B)2,000
C)4,000
D)200

Accepted Answer

According to the International Union for Conservation of Nature (IUCN), there are currently around 4,000 species of mammals in the world.

Question 8

There are a total of more than __________ primate taxa.
A)350
B)1,000
C)1,700
D)2 million

Accepted Answer

The answer of There are a total of more than...

Question 9

A mammal from the eutheria group __________.
A)will carry young in an abdominal pouch
B)lays eggs
C)does not produce milk
D)nourishes the embryo via a placenta

Accepted Answer

Mammals from the eutheria group are placental mammals, which means they nourish the embryo via a placenta. This is the defining characteristic of this group, and none of the other choices are correct. They do not carry young in an abdominal pouch like marsupials (choice A), do not lay eggs like monotremes (choice B), and produce milk like all other mammals (eliminating choice C).

Question 10

Primates are members of the __________ group.
A)prokaryotic
B)eutheria
C)prototheria
D)metatheria

Accepted Answer

Primates are mammals and therefore belong to the group Eutheria, which includes all placental mammals. The other answer choices (A, C, and D) are not correct since they refer to different groups of animals - prokaryotes (A) are unicellular organisms and prototheria (C) and metatheria (D) are both subgroups of mammals, but they refer specifically to monotremes (egg-laying mammals) and marsupials (pouched mammals), respectively.

Question 11

The primate order can be broken down into two suborders including the suborder __________.
A)strepsirhines Strepsirhini
B)prosimians Prosimii
C)haplorhines Haplorhini
D)all of these

Accepted Answer

The primate order is indeed divided into two suborders: Strepsirhini (or strepsirhines) and Haplorhini (or haplorhines). The term "prosimians" is an older classification that includes the strepsirhines and some early forms of haplorhines, but in modern taxonomy, primates are specifically divided into Strepsirhini and Haplorhini. Therefore, all the options provided are correct in the context of describing the suborders of primates.

Question 12

Biological anthropologists are interested in nonhuman primates because __________.
A)we share a common ancestry
B)studying their evolutionary history can teach us about evolutionary processes in general
C)because they are intrinsically interesting
D)all of these

Accepted Answer

Biological anthropologists are interested in nonhuman primates because they share a common ancestry with humans, studying their evolutionary history can teach us about evolutionary processes in general, and they are intrinsically interesting.

Question 13

Nonhuman primates exhibit a surprising lack of diversity of size and form.

Accepted Answer

Nonhuman primates actually exhibit a great diversity of size and form, ranging from the tiny mouse lemur to the large gorilla, and displaying various adaptations to different ecological niches.

Question 14

The primate body plan is highly specialized.

Accepted Answer

The answer of The primate body plan is highly specialized....

Question 15

The Australian platypus is a member of the prototheria group.Therefore,it __________.
A)gives birth to live young and feeds them from a nipple in an abdominal pouch
B)lays eggs
C)has a placenta
D)does not produce milk

Accepted Answer

Members of the prototheria group, which includes the platypus, lay eggs instead of giving birth to live young.

Question 16

All nonhuman primates are quadrupeds.

Accepted Answer

The answer of All nonhuman primates are quadrupeds....

Question 17

Primates achieve stereoscopic vision by having __________.
A)forward-facing eyes
B)large eyes
C)eyes that see well at night
D)round eyes

Accepted Answer

Stereoscopic vision requires forward-facing eyes, which allows for overlapping fields of vision from each eye and leads to depth perception. None of the other options are necessary for stereoscopic vision.

Question 18

Humans and apes are members of the __________ infraorder.
A)prosimian
B)anthropoid
C)haplorhine
D)strepsirhine

Accepted Answer

The answer of Humans and apes are members of the...

Question 19

Many strepsirhines move __________.
A)with bipedal walking
B)by arm swinging
C)by vertical clinging and leaping
D)by mostly swimming

Accepted Answer

Strepsirhines are primates that have a specialized form of movement called vertical clinging and leaping (VCL). They use their powerful hind legs to jump vertically and then cling onto trees using their grasping hands and feet. Arm-swinging is a form of locomotion used by some primates, but it is more commonly seen in other groups like gibbons and siamangs. Bipedal walking is a form of movement used by humans and some apes, and swimming is not a common form of movement for primates.

Question 20

In general,primates are typified by __________.
A)large brains
B)a high degree of learned behavior
C)grasping hands
D)all of these

Accepted Answer

All of these options are traits typical of primates. They have large brains relative to their body size, exhibit a high degree of learned behavior, and have grasping hands with opposable thumbs.
