Question 1

Very few primates are adaptive rule-breakers

Answer 1

False

Question 2

None of the anthropoids weigh less than 500 grams.

Answer 2

false

Question 3

Like lemuroids, platyrrhines evolved in isolation from all other primates.

Answer 3

True

Question 4

The primates of the Semiorder Haplorhini, Suborder Anthropoidea, and Infraorder Platyrrhini include the Superfamily_______ (with odd-faced New World monkeys) and the Superfamily______ which includes the rest of the New World monkeys.

Answer 4

Ceboidea and pithecoidea

Question 5

The Subfamily Callicebinae is represented by one genus with 30 species.

Answer 5

True

Question 6

The Subfamily Pitheciinae includes 3 genera of aptly named “odd-faced” monkeys!

Answer 6

True

Question 7

The Family Atelidae holds the only fully prehensile-tailed primates. These monkeys happen to be the largest platyrrhines in body mass.

Answer 7

True

Question 8

Spider monkeys, squirrel monkeys, and howling monkeys have fully prehensile tails.

Answer 8

False

Question 9

Both howling monkeys and wooly monkeys have schizodactyl hand but spider monkeys and muriqui monkeys lack thumbs!

Answer 9

true

Question 10

The Superfamily Ceboidea has two Families – the Atelidae which includes the only fully prehensile-tailed monkeys and the Cebidae which include one subfamily of semiprehensile-tailed monkeys, one subfamily with the only nocturnal anthropoid, and one family of highly-specialized monkeys with the smallest body weights of all platyrrhines and anthropoids.

Answer 10

True

Question 11

Including all of the capuchin genera together – these monkeys are known for allogrooming, tool-use, and general busy-bodied brainiest. This has helped to make the “organ grinder” monkey a favorite of casting directors for Hollywood films.

Answer 11

true

Question 12

Squirrel monkeys, like owl monkeys, live in small family groups.

Answer 12

false

Question 13

Owl monkey nocturnality is particularly unusual because they are descended from a diurnal ancestor and retain its retinal fovea. An additional interest fact is that they only have one type of visual sensory cell and are, as a result, color blind!

Answer 13

True

Question 14

Marmoset and tamarin dietary adaptations include tegulae (claw-like nails) that enable vertical climbing on tree trunks. Some taxa engage in “crop-rotation” and one species is the smallest-bodied modern primate.

Answer 14

true

Question 15

The Superfamily Cercopithecoidea has one Family – the Cercopithecidae. Cercopithecids are represented by cheek pouch monkeys in the Subfamily Colobinae and complex stomach monkeys in the Subfamily Cercopithecinae.

Answer 15

false

Question 16

Cercopithecines are primarily found in Africa and the nearby Arabian Peninsula; the rule-breakers in the group are the macaques. Colobones are primarily Asian but include red, olive, and black colobus monkeys in Africa.

Answer 16

true

Question 17

There are 22 macaque species that can be sorted into seven groupings. The success of this monkey is due to its generalized “do it all” adaptive flexibility.

Answer 17

true

Question 18

Mangabey look like and behave like macaques

Answer 18

false

Question 19

Baboons are obligate omnivores. Under the right circumstances, they would feast on fruit. However, these large-bodied and hungry primates live in huge groups and are constantly on the move in a search for calories to feed their large troops.

Answer 19

true

Question 20

Mandrills are the largest-bodied African Old World monkeys and are dedicated to fruit-procurement in western and central Africa.

Answer 20

true

Question 21

Sexual dimorphism is much more pronounced in catarrhines than it is in non-catarrhine primates.

Answer 21

true

Question 22

The guenon relatives include the smallest catarrhine (talopoin monkey) which, like another member of this group (Allen’s swamp monkey) is rare. The fastest primate in the world (vervet monkey) and the clever-generalist (patas monkey) that is very much like a New World monkey capuchin.

Answer 22

false

Question 23

The numerous species of guenon monkeys are distinct in pelage and facial patterns and coloration but are strikingly similar in relative body proportion dimensions (they simply scale up and down with body mass).

Answer 23

true

Question 24

All catarrhines love to groom but colobines engage in “aunting” behaviors that take allogrooming to a new level.

Answer 24

ture

Question 25

Cercopithecines are principally frugivorous to omnivorous and colobines are primarily folivorous.

Answer 25

true

Question 26

Cercopithecines include more terrestrial taxa than colobines.

Answer 26

true

Question 27

Despite dietary specializations and a preference for arboreal-living, the colobine sacred langur has successfully adapted to urban habitats.

Answer 27

true

Question 28

Most langur and leaf monkeys live in unimale-multifemale societies.

Answer 28

true

Question 29

The surprising odd-nosed colobines include the largest-bodied members of the group – as well as the best leapers and the most terrestrial taxa.

Answer 29

ture

Question 30

Lesser apes are more primitive than great apes.

Answer 30

false

Question 31

Hominoids include the largest living primates – up to 390 lbs. The largest hominoids are also extremely sexually dimorphic; the most extreme example may be the chimpanzee.

Answer 31

false

Question 32

Hominoids include every dietary adaptation except insectivory and all are crazy about fruit. They express every locomotor category except leaping and traditional quadrupedalism. They are equally diverse in social structure and have the longest interbirth intervals and juvenescence length of all primates.

Answer 32

true
