Question 5

Please describe two hypotheses that scientists have offered to explain the origin of Homo floresiensis.

Accepted Answer

The first hypothesis suggests that Homo

Question 6

You are interested in the historical pattern of colonization of a hypothetical primate species that evolved in South Asia and then spread to other parts of Asia, then to Europe, the Middle East, and finally to Africa. You hypothesize that a small number of individuals initially left SouthAsia, but you are unsure whether (1) this population rapidly and continuously expanded, spreading to the other regions of the world, or whether (2) colonization of each new region involved small groups of individuals breaking off and migrating to new locations. How could you use data on population genetic diversity to test these hypotheses?

Accepted Answer

To test these hypotheses, you could use

B)  cut marks on the fossil bones of large mammals 
C)  There is no evidence than non-Homo hominins used tools to gather meat. 
D)  a and b 
A)  blood stains on tools 
B)  cut marks on the fossil bones of large mammals 
C)  There is no evidence than non-Homo hominins used tools to gather meat. 
D)  a and b

Question 8

C)  Homo habilis originated in Asia. 
D)  Homo erectus originated in Asia. 
A)  Homo expanded out of Africa once.
