Question 1

1 / 1 pts

Which of the following bones provides evidence that a fossil animal was bipedal?

Correct!  

the pelvis and the foot

the pelvis

the hand

the foot

Question 2

1 / 1 pts

Derived characters are traits:

that characterize the last common ancestor of a particular collection of species

that are less well suited to the environment than ancestral characters

that are more complicated than ancestral characters

 Correct!  

that have evolved after the last common ancestor of a particular collection of species

Question 3

1 / 1 pts

Sahelanthropus chadensis is considered a hominin due to

its larger brain size

its bipedally adapted femur

 Correct!  

the placement of its foramen magnum

its lack of a tail

Question 4

1 / 1 pts

Characteristics that make a hominioid into a hominid include

reduced canine size

 Correct!  

all of these

larger brains in relation to body size

bipedalism

Question 5

0 / 1 pts

The earliest potential hominins (Sahelanthropus, Orrorin, Ardipithecus)

You Answered  

date to between 10-14 million years ago in African strata

all of these

 Correct answer  

each looked like what you might expect in a species close in time to the last common ancestor of Pan and Homo: mostly primitive, but with a few derived characteristics

each have numerous synapomorphies with later hominins that prove each of these genera belong in our tribe, Hominini

Question 6

0 / 1 pts

Correct answer  

Australopithecus anamensis

 You Answered  

Sahelanthropus tchadensis

Orrorin tugenensis

Question 7

0 / 1 pts

You Answered  

Savannah (open) habitats

Mountain (high altitude) habitats

Jungle (closed) habitats

 Correct answer  

Mosaic (mixed closed and open) habitats

Question 8

1 / 1 pts

Correct!  

True

Question 9

1 / 1 pts

Correct!  

True

False

Question 10

1 / 1 pts
