pter -- *no* information? might be a little strong. regression analysis with results of expermental evolution studies ( like lenski) would prob show sig mutual information btwn variant functional category and value of s. likely also applicable to diploid though obviously empiricalvalues of s much more fraught.

Seems that it would be interesting to see to what extent these colonization patterns were rooted in genetics. 
 
Is it a coincidence that Europeans could not colonize the heart of Africa? Most attribute it to heat tolerance and disease resistance. 
 
The army has collected data which show substantial differences in cold/heat tolerance between whites and blacks, in the predictable directions. 
 
This surely influenced settling patterns and eventuaLly political outcomes 
 
even within ethniciities is it a coincidence that the Finns colonzed the northern peninsula of Michigan?
