Here's a "What if...?"

Earth's North Pole is tilted away from the Sun at perihelion (close solar approach), allowing the mostly-water Southern Hemisphere to be heated by the sun 'more efficiently' due to distance.

Earth's North Pole is tilted toward the sun at aphelion (distant solar approach), allowing the mostly-land Northern Hemisphere to be heated more gently.

This arrangement allows for agriculture without roasting the crops in the ground, and the 'recharging' of Earth's 'thermal battery', so to speak.

What might the scenario be if this tilting were reversed? If the North Pole would be toward the Sun at perihelion, would we have anything resembling an agricultural phase in our past? Would we have 'evolved' from hunter-gatherers to communal agrarian societies?

And what would the effects on our global weather be, if the oceans were not warmed as they are on a regular basis with the current intensity of heat energy?

The tilts at perihelion/aphelion have greater significance to our development as a species and a civilization than most people realize (IMNSHO)...
