I think the use of "natural" selection terminology is sometimes a bit
misleading (misdirecting?). Any kind of selection will do, regardless of
the label. I'm not sure that the selection process is unnatural just
because it is a human process and/or the criterion for selection has
some component other than just survival (e.g., has some intellectual or
esthetic or economic component aside from ...uh.... natural economics).
