Final Jeopardy
3
C1-100-The answer is…
What two characteristics are common to all primates?
Binocular vision and movable fingers and toes
Back
4
C1-200-The answer is…
Why was the discovery of Lucy so important?
Showed that bipedalism came before a large brain
Back
6
C1-400-The answer is…What one thing do scientists look at on a fossil to determine whether it is a hominid?
If the bones indicate bipedalism
Back
10
C2-300-The answer is…
Do modern humans belong to the same genus as the australopithecines?
No – modern humans belong to the genus homo
Back
12
C2-500-The answer is…
Why were the finger drawings in the caves in Australia significant?
They demonstrated the ability to think abstractly
Back
13
C3-100-The answer is…
The oldest hominid fossils dated to 4.5 million years ago are known as?
Ardipithecus Ramidus
Back
17
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
18
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 dietBack
19
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
20
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
21
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
22
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
23
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
24
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
25
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
26
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
27
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
28
Final JeopardyWhat 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.
