That the Earth is a spheroid (WGS84 ?) is a model and the *model* "obeys" 
certain mathematical laws 
- because the mathematical laws are just rules of a language we invented for 
talking about such 
things.  The Earth, understood as some not completely knowable object in 
reality, doesn't obey 
anything.  Same with gene frequencies.  Gene frequencies are part of the map 
(theory of natural 
selection) not the territory.  It's easy to fall into confusing the map and 
territory because we 
have only maps to refer to and describe the territory.  Positivists recognized 
this and decided we 
should stop assuming that there is any territory - but this doesn't work 
because a map is only a map 
if it's a map *of* something.
