Biologists have considered two different
explanations to the rate of evolution: gradualism
and punctuated equilibrium. Which of the
following would indicate that an organism had
evolved via punctuated equilibrium?
a. The fossil record would show a slow, steady rate of change from a
common ancestor.
b. The fossil record would be incomplete, and numerous holes would
exist within the ancestral record.
c. The fossil record would show rapid change over an extended period of
time, with occasional periods of little change.
d. The fossil record would show little change over long periods of time,
followed by a sudden, brief period of rapid change.

The fossil record indicates that some organisms have become
extinct. However, some of these extinct organisms closely
resemble organisms that are still alive today.
Which of the following best describes why some extinct species in
the fossil record are similar to living organisms?
a.
b.
c.
d.
All organisms have identical genetic codes and therefore
produce similar features.
Organisms are related by a common ancestor that evolved
over a very long period of time.
Organisms adapted the same way to their environments in
order to produce beneficial traits.
Following mass extinctions, new organisms followed the
genetic path of the previous extinct organisms.

Circle Map
• For defining in context
• What does Hominid Evolution mean?
• Write Hominid Evolution on your paper and
draw a small circle around it
Hominid Evolution
Hominid Evolution Video
• Watching (10 - 15 minutes)
– the Prologue
– Evidence
• During the video Record any important facts/
information on your paper (circle map).
• What did we learn?
Circle Map
• After you wrote your details down draw a
larger circle around the information
• Then draw a large box around that for a “frame
of reference.”
Hominid Evolution
Circle Map
• Then draw a large box around that for a “frame
of reference.”
• This is for…
– How do you know what you know…?
– What could be influencing how you are thinking?
– Where did you get your information?
Hominid Evolution
Hominid Evolution Discussion
• Open your text books
– Page 380
– Look at figure 12.18
• What do you see?
• What do these organisms have in common?
• How are they different?
Hominid Evolution Vocabulary
• Each group will be assigned 1-2 vocabulary
words.
• As a group
– The word assigned should be defined using only 23 words
– 2 minutes to figure out definition
• Lets discuss as a class and fill in the definitions
for all the vocab. words on our handouts
Tree Map
• For Classifying
• We are going to classify the following groups
– Prosimians
– Anthropoids
– Hominoids
– hominids
Primate Classification
Comprehension Check
• Monday- List a trait that

which term?
a.
b.
c.
d.
adaptive radiation

Scientists theorize that it took a billion years or more for
oxygen in the atmosphere to reach the levels of today.
Based on this idea, the first cells could be classified as
which of the following?
a.
b.
c.
d.
aerobic and photosynthetic
anaerobic and heterotrophic
photosynthetic and unicellular
heterotrophic and eukaryotic
In the 1950s, Stanley Miller and Harold Urey conducted
experiments in which they fired electrical sparks in the
presence of a mixture of different gases. How did these
experiments contribute to the theory of the origins of life
on Earth?
a. They proved that organic molecules formed from the accumulation of
debris from space.
b. They showed that organic molecules could be formed from materials
available in the Earth's early atmosphere.
c. They determined that the age of organic molecules can be measured by
the half-life of isotopes.
d. They discovered that organic molecules would not have formed without
the presence of oxygen in the atmosphere.

Why does the fossil hominid known as "Lucy" get
mentioned so often in textbooks and lectures on
hominid evolution?
•
a. She's the oldest known hominid ever found
b. She lived millions of years before modern hominids
and yet looked very much like moderns in terms of her
skull size and shape
c. She's the most complete pre-modern hominid
skeleton ever found
d. At the time she was found, anthropologists thought
humans had evolved only about 1.75 million years ago.
But Lucy was at least twice that age and she was
definitely a hominid.
e. Because her species gave rise to all later hominid
species
