In my field (fish systematics/taxonomy) we have lumpers and splitters 
also - lumpers want to put a wide variety of critters under the same 
name, and splitters want to create zillions of new names for everything.  
Simlilar concept.

Exactly! In mathematics it's called Chaos  - there are so many interactig 
factors that a tiny deviance in one variable can lead to a profound 
difference in ultimate manifestations.
