Northerners’ brains are bigger: study


Populations in the north have evolved to cope with dull, cloudy skies and short periods of daylight.

Good news for people who are from the north: you are likely to have a bigger brain than your southern counterparts. Unfortunately, that doesn’t necessarily mean you are more intelligent than people from the south – just that you have evolved to cope with the longer winters and greyer skies in northern climates.
