Dear James,

     You say that you started this thread "as an example of the effects of
testosterone on human brain evolution."  Yes, I see......

     I am interested as to why you posted it to a women-in-bio newsgroup? 
I can't help but think you were hoping to start a stereotypical war
between the sexes kind of thread.  Given that this paper and all of the
findings similar to it are so inconclusive, and given that there seems to
be no reason to think that this particular newsgroup would have a focus
that would be able to shed any light on this paper in particular, I have
to wonder what your point IS, exactly?
