"All of the links available on brain evolution have mainly to do with size. There is not enough data to even speculate much on intraspecies differences........."
Then how could you make a statement that a theory regarding northern climate and democracy(a function of thinking) has NO bases.

"The moths did not change color because of coal soot. Coal soot helped them survive after a mutation, because it made it harder for birds to eat them."
The coal soot came first, the few dark color moths survived and thus passed on their genes, after a while all(or most) of the moths where now dark colors, environment played a big role in the evolution of that species

The environmental change, coal soot in the air made it more likely that moths with darker wings (gene for darker wings) would survive in that environment. That changed the gene pool, right?
