Richard Lewontin Quotes
The general public doesn't know and probably doesn't care about punctuated equilibria nor indeed should they, or the greenhouse effect on some other planet - they barely have the ability to cope with the greenhouse effect on their own planet. So I think you have to distinguish between the broad visibility of a scientist when he or she is speaking to a general public and trying to address general issues and the continued position that a scientist may have into the history of a particular subject.
