Back 4

diastema

Front 5

The evolution of apes began in Africa and continued into:

France

Front 7

Like that of Dryopithecus, a modern gorilla mandible has:

Back 7

a Y-5 molar pattern, low rounded cusps, large canines, and a diastema.

Front 8

The shift from the Miocene, which had greater diversity of ape species and fewer monkey species, to a living assemblage with greater diversity of monkey species and fewer ape species may be the result of:

Back 8

differences in ability to exploit the habitats that resulted after a change in global climate.

Front 9

Apes went extinct in southern Europe (including France, Spain, Italy, and Greece) during the late Miocene, probably as a result of:

Back 9

climate change.

Front 10

Plesiadapiforms are also called:

Back 10

proprimates

Front 11

Which two genera may be the ancestor to the orangutan?

Back 11

Gigantopithecus and Sivapithecus

Front 12

Chororapithecus is considered the:

Back 12

common ancestor of African apes and hominins.

Front 13

Gigantopithecus:

Back 13

stood ten feet tall and weighed 660 pounds.

Front 14

Which of the following apes has been proposed as the last common ancestor of living African apes and humans?

Back 14

Ouranopithecus

Front 15

Comparisons of tooth wear in living apes and extinct Miocene apes suggest that some extinct species of apes ate:

Back 15

leaves, nuts, and fruits.

Front 16

Monkeys underwent massive__________in the Pliocene and Pleistocene.

Back 16

adaptive radiation

Front 17

Which species of early primates had the most biological diversity?

Back 17

Proconsul

Front 18

The best-accepted hypothesis for the dispersal of African monkeys to the New World is:

Back 18

platyrrhines evolved from anthropoids in Africa that migrated across the Atlantic to South America.

Front 19

The angiosperm radiation hypothesis proposes that:

Back 19

certain primate traits were responses to the acquisition of fruit during the Cenozoic.

Front 20

A difference between Miocene apes and modern apes is:

Back 20

the size of the hands.

Front 21

A rapid temperature increase about 55 mya created tropical conditions around the world, resulting in the

Back 21

adaptive radiation of Euprimates.

Front 22

During the Miocene epoch of the Cenozoic era, there was an adaptive radiation of which kind of primate?

Back 22

apes

Front 23

Which Eocene organisms had clear primate characteristics like a postorbital bar, opposable thumbs, nails, and a large brain?

Back 23

adapids and omomyids

Front 24

Canadian primate paleontologist David Begun proposes that climate changes in Europe prompted late Miocene apes to

Back 24

move from Europe back to Africa following food sources.

Front 25

Paleocene organisms that may have been the first primates were:

Back 25

plesiadapiforms

Front 26

Euprimates represent the:

Back 26

first true primates
