The seasons would occur as usual even without axial rotation -axial
rotation generates daylight and darkness and changing orbital
orientation to the central Sun generates seasonal daylight/darkness
variations,
Standing on the Earth's polar axis is equivalent to a non rotating
Earth,it stands to reasons that seasonal daylight/darkness variations
are at the extremes while the effect becomes less variable towards the
Equator (where no seasonal variations are seen).
Through this reasoning,there is a much better way to explain the
seasons but alas,geodynamics is in a poor state at the moment and
replacing the pseudo-dynamic of variable axial inclination with a new
orbital component which causes the daylight/darkness variations may
take a while.
Hope this helps.
