Dear Gijs and Paul;-
        I understand the problem I have proposed. If it were not a significant
problem, someone would have solved it a long time ago. All I am saying
is that science has taught us that there ARE trends, solutions, etc. And
electronics has taught us that solutions can be quantified.
        Simplification of questions:
        1. How many points of difference and of what quality are needed to
diferentiate Species?
        2. How many points of difference and of what quality are needed to
diferentiate Genera?
        3. How many points of difference and of what quality anr needed to
diferentiate Families?
        We (a very collective WE) should be able to come up with some sort of
formula.
        As for me: I can tell the difference between a Tulip and an Elephant.
---but it took some study.
