As the temperatures plunge and we are faced with cyclone bombs, storms that arise in a way unprecedented for their ferocity and speed of formation, I think back to my piece about intelligence and why white and yellow people may be inherently better problem solvers in areas of technology than dark-skinned people.
One word, winter. Winter creates a unique challenge to inhabitants who have to survive long periods without heat or vegetative growth. Our skin changed to allow us to absorb more vitamin D and be less prone to rickets, but the really great change was in our brains. We had to plan for long periods without resources being abundant. We had to create places where we could remain protected from the elements, have warmth. Planning for the future, using innovative technology, being constantly on the lookout for any advantage, these are the legacy of winter survivors from the past.
Think of space travel as an extended winter. Think of sea living. Think of all vessels that protect us from hostile conditions as having developed from the first caves we ventured into to escape the cold. Think of fire as the first way of harnessing heat to our will. Think of a stone as being the first weapon. The first utensil being a stick to hold a piece of meat over a fire or a way to get termites. Think of winter as God's gift to humanity. Or maybe its greatest curse, depending on how we use our ingenuity.
