Wheel

Symbol of mass transportation, crucial as a pair of wings; wonder where we'd be without it in the broader scheme of things? It's hard to say just how we'd cope, indeed, how we'd get around. I must confess a nagging fear that we'd stay right on the ground; not much further than Cro-Magnons dragging women by the hair, as they forage in the jungle lugging trophies to their lair! Our trips would be restricted to the tribe across the marsh; we'd just better hope they're friendly, not belligerent or harsh! The prospects weren't too sanguine that we'd subjugate the land until the wheel's invention guaranteed our upper hand!
