Episode 1: Hadar
 Please plug-in your head-phones.
1. Why is Hadar so important for those studying human origins?
 Under the ‘Contents’ section (located on the left hand side of the screen), navigate your mouse and single
click on “Becoming Human: the documentary. Wait for the program to load and then single-click on “Begin
the Program”. Then, please answer the following questions.
2a) In what year did Donald Johanson make his first fossil hominid discovery?
1.
b) What human fossil did he find?
Who we are as a species and where we come from make up a fantastic story spanning how many years?
.
c) How old was the specimen he found?
2a) What is the name of the host of this web-documentary.
b) What is his occupation?
.
d) How did Johanson determine the age of this fossil?
3. The story of human origins begins (state location)
when our ancestors first did what?
?
e) What did detailed analysis of the fossil reveal about the physical characteristics of the human ancestor he
found?
4. Over millions of years, what happened to our ancestors?
Where did they go?
.
.
?
Episode 2: Lucy
5. What happened to the various species of our human ancestors?

afarensis mean?

Episode 3: Reconstructing Environments
1. What does Kaye Reed do as a “Paleo-ecologist”
 Scroll your mouse to the top of the screen and single click on the ANATOMY MODULE. Play the
documentary.
Episode 1: The Common Ancestor
1.
2.
What was Hadar’s environment like 3 million years ago?
In which year?
2.
3.
Why was Lucy vulnerable in her environment?
4.
What physical traits allowed Lucy to preserve herself in her environment?
 Scroll your mouse to the “RELATED EXHIBITS” section at the bottom of your screen. Single click on
option #5: “The Dating Game” and answer the following questions:
Due to a variety of anatomical and molecular studies, which primate is considered to be the closest living
relative of modern humans? What % genetic similarity exists between humans and this primate?
.
3.
.
Who proposed that humans and African apes must have shared a common ancestor?
What does this close genetic similarity NOT mean? ( 2 ideas)
a)
b)
c) What, however, DOES this close genetic relation mean?
RELATED EXHIBIT: “The Dating Game”
1. What is dated when the age of fossils is determined?
2. Why does this section say that 20,000 years is not a very big margin of error?
4. What sort of variety of ape life existed in African forests 8 million years ago?
5. As we travel back in time, our ancestors look less like
6.
.
and more like
What anatomical features allowed our ancestors 8 million years ago to be successful in the lush African
forests? (2 things)
3
5. What areas of primate life would bipedalism improve?
7. When did the world climate change after this? How did the climate change?
5.
8.
How did the change in world climate affect the lush African forest the early Apes lived in? ( 2 things)
So, Paleoanthropologists have concluded that the central anatomical feature that separates Australopithicus
from Apes is:
.
Episode 3: Turkana Boy
9. What happened to most ape species?
Note: Australopithicus is the first hominid genus (=set) of our early ancestors. The second genus (family) of
hominids is called Homo. A Hominid is a specific family of primates. Primates make up one order of
Mammals.
9.
1.
When did the genus Homo first appear?
2.
What can’t experts agree on, regarding the genus of Homo?
What happened to the other ape species?
10. So—who/what is the common ancestor between apes and humans?
3. By 1.8 million years ago we encountered a hominid called:
who stands in contrast to all earlier human ancestors.

6.
What did Alan Walker discover about what Homo Erectus ate?
3.
