Question 3

Based on recent DNA evidence,it is clear that Homo sapiens did not evolve in Africa.

Accepted Answer

Recent DNA evidence actually confirms that Homo sapiens did in fact evolve in Africa. Studies of human genetic diversity have shown that the greatest amount of genetic variation is found in African populations, indicating that this is where our species originated. Additionally, analyses of ancient DNA from early human fossils also supports the African origin hypothesis.

Question 5

Archaeomagnetic (or,"paleomagnetic")dating is based on the constantly changing magnetic field of the earth.

Accepted Answer

Archaeomagnetic (or "paleomagnetic") dating is based on the fact that the earth's magnetic field has changed in the past and continues to change in the present. By studying the magnetic properties of archaeological materials, scientists can determine when those materials were last heated and use that information to date them.

Question 6

Discuss the basic method of tree-ring dating (dendrochronology).Include in your discussion the techniques used by dendrochronologists to obtain tree rings,and how the formation of these rings is affected by environmental conditions.Be certain to include in your discussion 1)how tree rings are used to create long master sequences and allow the calibration of radiocarbon dating,and 2),how tree rings are used for direct dating.Finally,what are the limitations of the method?
