Prologue

1.Where did our ancestors first “stand up?

2.Some species adaptedto the changing world while others went extinct.

3.What is the single species of humans that has survived?

4.What is a hominid?

5.What does bipedal mean?

Evidence

1.  Hadar, Ethiopia is an area rich in animal fossils dating to about.

2.  What year did Donald Johanson (the narrator) make his 1st fossil discovery?

3.  What year was the fossil dated to (how old is it)?

4.  What part of the body was it?

5.  Lucy, the “ape that stood up” was discovered in 1974.  Why was she named “Lucy?”

6.  What species is Lucy?

7.  How old is Lucy?

8.  Why is Lucy significant in evolution?

9.  What is the job of a Paleo ecologist?

10.  Why is this important?

11.  How does Hadar today compare to Hadar 3 mya?

12.  Why is it important to work closely with the local people, like Kaye Reed works with the Afar people?

13.  List three physical characteristics of Lucy (based on her skeleton).

Anatomy

1.  In 1871, what did Charles Darwin propose about modern humans and apes?

2.  What is the closest living relative to humans?

3.  True or False: We evolved from chimps.

4.  What are the Laetoli Footprints

5.  How did they form? 

6.  What species is thought to have produced the hominid Laetoli footprints?

7.  How does the structure of the human foot differ from chimps?

8.  Bipedalism is thought to have evolved because of the positive effects it had on evolving species.  List four things mentioned that bipedalism allows.

9.  What is the initial feature to set us apart from apes?

11.  How do the skeletons of Homo erectus compare to earlier ancestors?

12.  The easiest way to get a big brain is to get a big

14.  1 ½ million yearsHomo erectus left Africa and began to.

Lineages

1.            How is Homo neanderthalensis structurally different from modern humans?

2.  How long did Neanderthals exist?

3.  Are Neanderthals our direct ancestors?

4.  Why is it thought Neanderthals became extinct?

5. What does modern DNA technology suggest about the Neanderthal genome?
