Re: New DNA Tests done on the Hemings-Jefferson Controversy

by "reatty" <reatty@[EMAIL PROTECTED] > May 19, 2007 at 09:39 AM

Dear Sam- as a stupid person, I eagerly await your analysis (no irony or 
sarcasm intended). Aside from the Hemings/Jefferson controversy, this
whole 
DNA ancestry thing is interesting. I have one off topic question. What's
the 
purpose of this type of testing of individuals? It's interesting to know
the 
answer, but does it advance knowledge of human evolution or what?

Stupidly yours, Stultus Americanus
