Dear Dick,

You are right. One unused gene will drift through mutation to junk, and its
presence can still be useful. But it is not a rule (of course, because we are
talking about science). I was just trying to say to David Thorton that 
not "all" of junk DNA can be coding.
Anyway, I thank you about the reference. I think it will be very useful. 
But our library hasn't receive this Journal(8) yet. I will have to wait 
one or two months to read it...   


Best,  Ro.
