Robert,Doesn't a lot of that discussion parallel the debate about Gould and Lewontin's spandrels <http://en.wikipedia.org/wiki/Spandrel_%28biology%29>?
Well, it might. I once thought I understood their arguments (most of which I read in the /NYRB/) but now I've forgotten them. I remember siding with Lewontin; but why I did, I couldn't now.say.
Thanks. Robert Paul
