It would seem that camouflage would be more significant, as in the desert reptiles, though why Baltic grain farmers would benefit more than hunters and gatherers is not clear, unless the grain there differed from others (winter wheat?).

I thought I knew a little bit about how mutations work - clearly I have much to learn. Great example – good pick up!
