JE:-
No ambiguity exists in the above quote which only
deals with what _Hamilton_ meant as a cost and has
nothing at all to do with what I mean as a cost. 

Please answer the question put to you: 
Do you agree or disagree with Dr 
O'Hara's answer in the quote (above)? 
A simple "yes" or "no" will suffice.

Also:
What is "a marginal fitness cost"?
Does it differ to BOTH a relative 
AND absolute fitness cost?
