 *::::Okay, apology accepted. What I am saying (and this is very important for a beginning graduate student) is that none of us are really that familiar with all that is going on in a given field unless we are the guy asked to write a review article for the Annual Review of Ecology, Evolution, and Systematics. Anyway, I was told a few things about carnivorous plants, including the almost fact that they make poor model organisms, and that they are under selection for obtaining and utilizing nitrogen efficiently. It may be that I heard the genome size thing in seminar, so I will have to find more written sources. Rest assured that the idea has been bubbling around for quite a while now.
