Back
7

Back
9
C2-300-The answer is…

Back
10

Europe – mainly in the area of France
Back
11
C2-500-The answer is…
Why were the finger drawings in the
caves in Australia significant?
They demonstrated the ability to think
abstractly
Back
12
C3-100-The answer is…
The oldest hominid fossils dated to 4.5
million years ago are known as?
Ardipithecus Ramidus
Back
13
C3-200-The answer is…

Making tools
Back
14
C3-300-The answer is…
What does Prehensile mean?
The ability to grasp
Back
15
C3-400-The answer is…
What was the purpose of the sagittal
crest?
To attach big jaw muscles
Back
16
C3-500-The answer is…
What information can you get from
fossilized skull fragments?
Size of brain, whether they had a brow
ridge or sagittal crest.
Back
17
C4-100-The answer is…
What information can you get from
fossilized teeth?
Diet, wear patterns can tell you about
other activity (animal skins), what the
environment was like from their diet
Back
18
C4-200-The answer is…
What are three characteristics unique
to anthropoid primates?
Well developed collar bones
Rotating shoulder joints
Opposable thumb
Similar dental formula
Large brain to body size
Back
19
C4-300-The answer is…
Name anatomical features that support
bipedalism.
Cup shaped pelvis
S-shaped spine
Foramen magnum at bottom of skull
Short aligned toes
Stiff knee below body
Back
20
C4-400-The answer is…
What are the advantages of being a
biped?
Use of hands for carrying children and food, for
protection, for feeding, for play or gesture
Less heat loss
Able to travel farther – more efficient locomotion
Back
21
C4-500-The answer is…
How did bipedalism increase fitness?
Able to eat more efficiently with hands
Better able to take care of/protect young
Able to see farther for food or predators
Back
22
C5-100-The answer is…
Summarize the multiregional
hypothesis.
Modern humans evolved in parallel
worldwide from Homo erectus – must
have gene flow between populations
Back
23
C5-200-The answer is…
Explain the African origin hypothesis
Modern humans originated in Africa
100,000 – 200,000 years ago and then
migrated into the rest of the world.
Back
24
C5-300-The answer is…
When it comes to hominids, what is
the relationship between body size and
brain size?
Direct proportion – bigger body =
bigger brain
Back
25
C5-400-The answer is…
Compare the skull of a human with
that of a gorilla.
Gorilla: brow ridge, prognathic face, foramen magnum at
back of skull, sagittal crest, u-shaped jaw
Human: small face, no brow ridge, flat face under skull,
V-shaped jaw, foramen magnum at bottom, no sagittal
crest
*Both have similar dental formula
Back
26
C6-500-The answer is…
How were Neanderthals different from
Cro-Magnon’s?
Neanderthals had heavy bones, thick
brow ridges, large protruding teeth,
shorter but very heavily built
Back
27
Final Jeopardy
What was the final theory in the Neanderthal movie? What evidence
do scientists have to support it? What evidence disputes it?
1. Neanderthal and Cro-Magnon interbred
2.
Skeleton of 4 yr. old boy found that dates 3000 years after
Neanderthal. Skull similar to Cro-Magnon but skeleton similar to
Neanderthal
3.
Dispute: there is no DNA evidence of Neanderthal genes in our
sequences.
