Accepted Answer

A)   Modern humans out-competed and replaced other populations as they migrated around the world.
B)   Extensive gene flow between human populations led to a blending of traits that resulted in the evolution of modern humans.

Question 10

Which of the following is true?

Accepted Answer

A) True 
 B)False

Question 12

Which of the following is not true about archaic Homo sapiens species?

Accepted Answer

A)   They have been found in Africa.
B)   They developed ways of making tools.
C)   Neandertal was an advanced type of archaic H. sapiens.
D)   They were more primitive than H. habilis.

Question 13

By about a half million years ago, our human ancestors were probably hunting large game and using fire.

Accepted Answer

A) True 
 B)False

Question 14

What potential effect might the current amount of gene flow among human populations have on these populations?

Accepted Answer

A)   It could cause different populations to become increasingly more different until they are reproductively isolated.
B)   It could significantly reduce the amount of variation between different human populations.
C)   None, because isolated groups of humans are actually separate species.
D)   Gene flow does not occur between human populations.

Question 15

If the Neandertals are not the direct ancestors of humans, is it still possible for humans and Neandertals to be related?

Accepted Answer

A)   Yes, because we share a common ancestor.
B)   Yes, but only if humans and Neandertals could have interbred.
C)   No, because the human evolutionary tree is strictly linear and without branches.
D)   No, because this means that Neandertals evolved from an entirely different branch of organisms than humans did.
