I separated these two as being my guiding stars for working with fuzzy species.

Contrasting the patterns in different types of data is truely invaluable.

And I have found that if one psychologically needs to live in an ordered universe, with a high degree of precision and control, that person may be very unhappy when confronted by the chaos of fuzzy species. For there is a truely is complex intereaction of genes, time, and environment that causes unclear, or fuzzy species boundaries, they are a real phenomena, not just a failure of the scientist. I hope you will never be suprised to find out that the organic world cannot be simply pigeon-holed into taxonomic classifications.
